Skin Care FAQ - Knowledge Base

Skin Care Knowledge Base (FAQs)

Clear answers to the skincare questions we hear most, from layering serums to why pH matters. This skincare FAQ is written for everyone who cares for skin, from estheticians and skin professionals to anyone building a simple daily routine, and backed by the expertise of esthetician Shunri MacQuarrie, founder of Shunly®.

General Skincare Questions

Seasonal changes affect your skin — but the core skincare steps remain the same:

Exfoliate • Hydrate • Protect

1. Exfoliate — All Year for Clarity & Absorption

Dry winter air and summer oiliness can both lead to buildup of dead skin cells. Without exfoliation, your skin may appear dull, and even the best serums can’t absorb as well.

Why it matters:

  • Preps skin to absorb active ingredients.
  • Smooths dry patches and keeps pores looking clear.
  • Keeps skin smooth and glowing.

Shunri recommends:

Pro tip: AHAs (like glycolic and lactic acids) are a gentler everyday choice than gritty scrubs. They smooth the surface without scratching it.

2. Hydrate – It’s About Water, Not Oil

Both dry and oily skin can suffer from dehydration (lack of water). In summer, sweat and sun exposure dehydrate the skin. In winter, heaters and low humidity strip away moisture.

Why it matters:

  • Supports elasticity and skin function.
  • Helps prevent flaking, tightness, and oil imbalance.
  • Prepares skin to better absorb treatments.

Step 1: Add Antioxidants First

These antioxidant serums help defend skin against environmental stressors, brighten, and soften the look of aging.

Step 2: Layer Hydration Based on Skin Type

Normal to dry skin:

Oily or blemish-prone skin:

Tip: Well-hydrated skin looks more balanced, feels more comfortable, and absorbs treatments better.

3. Protect — From UV, Year-Round

Many people think sunscreen is only needed in summer, but UVA rays — the ones that age skin — are present 365 days a year, even indoors or on cloudy days.

Why year-round SPF matters:

  • UVA rays contribute to visible aging: wrinkles, loss of firmness, and dark spots.
  • UVB rays cause sunburn and are strongest in summer, but they also reflect off snow and water.
  • Both contribute to premature skin aging.

Shunri recommends:

  • Use a Shunly mineral sunscreen with zinc oxide protection.
  • Wear it daily, rain or shine.
  • Reapply at least every 2 hours outdoors, and after swimming or sweating.

Tip: Consistency beats intensity. The same simple routine, lightly adjusted for the season, keeps skin looking its best all year.

Yes — toner plays a vital role in a healthy skincare routine.

Toners are often misunderstood or considered optional, but a well-formulated toner is essential for maintaining your skin’s balance and enhancing the effectiveness of your routine.

After cleansing, your skin’s pH can shift toward alkaline, leaving it off-balance. This can lead to:

  • Reduced product absorption
  • Dryness or buildup
  • A tight or sensitive feel

The right toner brings skin back to its natural, slightly acidic balance and preps it to absorb what comes next — like a sponge that’s perfectly primed to soak in hydration.

Why not all toners are equal:

Heavily astringent toners can leave skin feeling tight and stripped.

Instead, choose a toner that:

  • Leaves skin feeling calm and refreshed
  • Balances pH
  • Preps skin to absorb your serums

Shunly pH-Balancing Toner, powered by FUSION FORMULA®

Shunly’s FUSION FORMULA® pH-balanced toner brings skin back into balance after cleansing, so every next step absorbs better. Our CoQ10 + A-Oxy Toner is packed with antioxidants and energizing CoQ10 to prep skin for hydration and a visibly refreshed glow.

The delicate skin around the eyes needs special care

The skin around the eyes is thinner and more sensitive than the rest of the face. It’s more prone to dryness, fine lines, puffiness, dark circles, and signs of fatigue. Regular facial products may be too heavy or not targeted enough for this area.

That’s why Shunly offers targeted formulas for the eye area, each designed for a different concern.

  1. L-AA + Instant Eye Gel: Brightening + Antioxidant Protection
  • Powered by L-Ascorbic Acid (Vitamin C), Glutathione, and Alpha-Arbutin, this gel targets the look of dullness, uneven tone, and early signs of aging.
  • Helps the delicate eye area look brighter and firmer while hydrating with Aloe Vera, Bioflavonoids, and Hyaluronic Acid.

Best for: Tired-looking eyes, dullness, and the look of dark circles.

2. Luminous Face Lift 01 Serum: Firming + Instant Lift Effect

  • Infused with Algae Extract, Wheat Protein, and Kaolin, this serum delivers an instant tightening feel and a visibly lifted look.
  • Minerals and hydrators help skin look smoother and more toned.

Best for: A lifted look around the eyes and softer-looking fine lines.

3. Luminous Face Lift 02 Lotion: Hydration + Peptide Care

  • Contains Ginseng, Chamomile, and a blend of powerful peptides like Palmitoyl Tripeptide-1 and Acetyl Hexapeptide-3 to hydrate and leave skin looking plumper and smoother.
  • Lightweight and soothing, it helps ease dryness and the look of fatigue around the eyes.

Best for: Hydration, a plumper look, and visible signs of aging.

Every Shunly eye-area formula follows our 3 SkinCareActs™ philosophy: Prevention, Protection, and Correction in every bottle.

Your skin thrives on consistency — with mindful adjustments.

The skin is highly responsive to internal and external changes — including diet, hormones, stress, weather, and environmental conditions. Sudden or frequent changes to your skincare routine can disrupt your skin’s natural barrier, leaving it feeling irritated or out of balance.

Should you ever change your skincare?

Yes — but thoughtfully. It’s best to maintain a core skincare routine year-round that supports your skin’s baseline health and keeps it balanced. This core routine should include products that:

  • You know are compatible with your skin.
  • Keep your skin feeling comfortable.
  • Address your general skin type and concerns.

Once this stable foundation is in place, you can introduce one new product at a time — such as a seasonal booster, eye serum, or treatment — depending on your skin’s changing needs (e.g. dehydration in winter, more oil in summer).

Pro Tip: Give each new product at least 2–4 weeks before assessing its effectiveness. Introducing too many products at once can make it difficult to determine what’s helping or what might be causing a reaction.

Shunri recommends: Build a reliable 3 SkinCareActs™ routine as your foundation, and adjust only when needed. Shunly formulas are designed to work together, so your routine can evolve without starting over.

Yes — daily sun protection is essential, even indoors.

UVA rays are present year-round, regardless of season or weather. Unlike UVB rays, which cause sunburn, UVA rays pass through windows and glass, reaching your skin while you drive, sit by a window, or walk short distances outside — to the car, for coffee, or to pick up lunch. These rays contribute to premature aging, loss of firmness, and dark spots.

Daily SPF = Daily Skin Defense

Even if you’re indoors most of the day, your skin still sees daylight through windows. Daily sunscreen is one of the simplest ways to help prevent sunburn and early signs of skin aging caused by the sun.

Shunri recommends:

A daily Shunly mineral sunscreen: zinc oxide protection with a lightweight feel, never heavy or greasy. Suitable for all skin types, including sensitive and redness-prone skin.

No. Shunly products are paraben-free, by choice.

We formulate with purposeful, well-researched ingredients chosen for both performance and skin comfort. That includes leaving out parabens, a common cosmetic preservative many people prefer to avoid.

Instead, we use modern preservative systems that keep every formula fresh and stable.

What does this mean for your skin?

  • No parabens.
  • Formulas kept fresh and stable.
  • Designed for all skin types, including sensitive skin.
Our goal: visible results through purposeful, intelligent skincare, grounded in our 3 SkinCareActs™ philosophy.

No. Shunly is cruelty-free.

We do not test our products on animals, and we do not ask others to test on our behalf. We believe skincare should never come at the expense of animal welfare.

Hydration comes from water, not oil.

Most skin that feels dry is actually dehydrated: short on water, not oil. Heavy creams can sit on the surface and leave skin feeling coated while it still lacks hydration underneath.

Shunly’s approach is Hydration Without Moisturizer:

The result: skin that feels hydrated, soft, and balanced, never greasy.

Shunri recommends: Give it 2–4 weeks before deciding. Most clients are surprised how comfortable their skin feels.

How To Use Our Products

Daily SPF is not optional — it’s your skin’s best defense.

Your face, neck, and eye area are the most exposed parts of your skin — and the most vulnerable to sun damage that leads to:

  • Premature aging (fine lines, sagging, discoloration)
  • Uneven tone and texture
  • Loss of firmness over time

Even if you don’t “tan,” daily UV exposure still causes invisible photodamage — especially UVA rays that penetrate windows and clouds.

Why Shunly FUSION FORMULA® SPF is different:

Our mineral SPF formulas pair broad-spectrum zinc oxide protection with skin-caring ingredients — our FUSION FORMULA® approach. Your skin gets protection plus:

  • Antioxidants to help defend against environmental stressors
  • Hydrators for a comfortable, moisturized feel
  • Calming ingredients suited to sensitive, redness-prone, or post-facial skin

Gentle enough for:

  • Daily wear on all skin types
  • Application around the delicate eye area
  • Use after professional facials and treatments

The result:

Your skin stays protected, calm, and radiant — without a greasy or chalky feel.

For best results, use a two-step cleansing method — even if you don’t wear makeup.

Throughout the day, your skin accumulates:

  • Makeup
  • Sunscreen
  • Environmental pollutants
  • Sweat and oil

A single cleanse mainly lifts the surface layer. A second cleanse deep-cleans pores and leaves skin looking clear and fresh.

Step-by-Step Cleansing Guide:

Remove surface impurities (makeup, sunscreen, buildup)

Use 3-in-1 Makeup Remover in one of two ways:

Without water:

  • Make sure your hands and face are dry
  • Apply a small amount and massage gently to dissolve makeup and residue
  • Wipe away with a soft cotton pad or tissue

With water:

  • Apply the remover to dry skin, massage, then emulsify with a small amount of water
  • Rinse thoroughly

This flexible formula is ideal for travel, sensitive skin, and professional use.

Step 1. First cleanse: Remove surface buildup.

  • Wash your hands: Start with clean hands so you don’t transfer oil or dirt to your face.
  • Dispense a moderate amount of the Shunly cleanser that suits your skin type (all, dry, or oily/blemish-prone).
  • Lather with a small amount of water
  • Massage gently
  • Rinse with lukewarm water

Step 2. Second cleanse: Purify the skin.

  • Dispense a moderate amount of cleanser, lather with a small amount of water, and massage over the skin in circular motions.
  • Rinse thoroughly with lukewarm water.

Step 3. Restore balance: Follow with the Shunly pH-balancing toner.

Pro Tip:  Wash your hair before cleansing your face, so shampoo and conditioner residue don’t stay on your skin.

Toners are not just a refresh — they are an essential step in every routine.

Healthy-looking skin depends on the right pH balance. Cleansing, tap water, and the environment can throw it off, leaving skin feeling dry or tight and less ready to absorb treatments.

That’s why the Shunly pH-balancing toner is formulated to rebalance skin after cleansing and prep it to absorb serums and antioxidants.

How to Use:

  • Spray directly onto the skin: Mist over the face, neck, and décolleté. Avoid using cotton pads, as they absorb product and prevent your skin from receiving the full benefit.
  • Tap to activate absorption: Use clean fingertips to gently press or tap the toner into the skin until fully absorbed. Tapping helps the toner absorb fully.
  • Follow with your treatment serum

Suitable for all skin types, including sensitive skin. Shunly toner hydrates and rebalances, helping every step that follows perform at its best.

Pro Tip: During colder months or when skin feels dry, double-mist your toner. After the first layer is absorbed, spray again for an extra boost of hydration before applying your serums.

Retinol should always be used at night — never during the day.

Vitamin A (the retinoid family, including retinol) is one of the most well-researched skincare ingredients for smoother-looking skin, softer-looking fine lines, and refined texture. Because it can make skin more sensitive to the sun, use it only at night, even if you wear SPF.

Using retinol in the morning may lead to:

  • Increased sun sensitivity.
  • Irritation or uneven-looking tone
  • Reduced effectiveness of the ingredient

When and how to use it

Use Only In Evening:

  1. Cleanse your face
  2. Mist on your Shunly pH-balancing toner to rebalance
  3. Apply the Shunly vitamin A treatment for your skin type:

Vita A, E + Ceramides Treatment: Ideal for normal to dry skin. Hydrates while refining texture and softening visible signs of aging.

Vita A + C Treatment: Ideal for normal to oily or blemish-prone skin. Pairs vitamin A with vitamin C to brighten and refine the look of pores.

4. Finish with a hydrating serum if needed. Avoid layering with other exfoliants (AHA, BHA, or strong brighteners) on the same night unless recommended by a professional.

Morning care is just as important:

Even if retinol is only used at night, it is essential to:

  • Use a broad-spectrum SPF every morning.
  • Apply antioxidant serums to help protect your skin and maintain the results.

Important Notes:

  • Start by using 2–3 nights per week. If your skin tolerates it well, you may increase to every other night, and eventually nightly use as recommended.
  • Mild dryness, flaking, or a few temporary breakouts may happen while your skin adjusts. This usually settles within a few weeks; if irritation continues, stop use and check with your esthetician or dermatologist. Avoid exfoliants on the same night.
  • Avoid applying retinol to the eyelids, lips, or corners of the nose where the skin is thinner. If skin feels sensitive, apply SE + Apple Skin Stem Cells before or after your vitamin A treatment.

Avoid retinol use if:

  • You are pregnant or breastfeeding.
  • Your skin is sunburned, irritated, or broken.
  • You are undergoing certain clinical treatments (consult your esthetician or dermatologist).

Serums are concentrated formulas that deliver active ingredients where your skin needs them.

Unlike heavy moisturizers that mostly sit on the surface, serums are lightweight and concentrated, with antioxidants, vitamins, peptides, and exfoliating ingredients that target specific concerns like:

  • Visible sun damage
  • Uneven tone
  • Fine lines and wrinkles
  • Dryness or congestion
  • Loss of firmness and radiance

Morning: Start with antioxidant protection

Think of your morning serum like a daily multivitamin for your skin. Antioxidants such as vitamins C and E and ferulic acid help defend skin against environmental stressors for a brighter, healthier-looking complexion. Always pair them with SPF.

If your skin feels balanced and hydrated, you may follow your serum directly with Shunly SPF. No extra serum is needed in the morning.

Evening: Rotate your serums, the way a professional would

Each Shunly serum has a specific purpose. Instead of using the same one every night, Shunri recommends a weekly rotation that covers every need, just as estheticians target different concerns on different days in the treatment room.

Weekly Serum Rotation Plan (Example):

Day: Focus - Recommended Serum

Mon: Exfoliate – AHA + Rapid Exfoliator (smooth + renew)

Tue: Hydrate + Firm – B3, B5 + Peptides Hydra Gel (hydrate + firmer look)

Wed: Brighten – KA + Bio Lightening Treatment (tone + clarity)

Thu: Revitalize – SE + Apple Skin Stem Cells (hydrate + revitalize)

Fri: Vitamin A – Vita A + C Treatment or Vita A, E + Ceramides Treatment (smooth + refine)

Sat: Exfoliate – repeat Monday

Sun: Hydrate + Firm – repeat Tuesday, and so on.

Why this rotation works:

  • Each serum targets different skin functions (exfoliation, hydration, brightening, firming, revitalizing).
  • Rotating serums gives skin a full range of benefits without overdoing any one active.
  • Over time, skin looks smoother, more radiant, and more resilient. See the full routine in Hydration Without Moisturizer.

Thin to thick, and always finish with SPF in the morning.

Morning

  1. Cleanse
  2. Mist pH-balancing toner, then tap it in
  3. Antioxidant serum: B,C,E + Ferulic Treatment or CE + Asiatic Treatment
  4. Eye gel: L-AA + Instant Eye Gel
  5. Hydrating serum, if needed
  6. Shunly mineral SPF

Evening

  1. Remove makeup and SPF with 3-in-1 Makeup Remover, then cleanse
  2. Mist pH-balancing toner
  3. Tonight’s treatment serum from your weekly rotation
  4. Eye gel
  5. Hydrating serum, if needed
Pro Tip: Let each layer absorb for 30–60 seconds before applying the next.

It depends on your skin, and on what it’s been carrying.

Every skin is different. If you’ve used heavy creams or moisturizers for years, a layer of buildup can sit on the skin’s surface. Your skin may need a few extra weeks to adjust as that buildup clears.

Once it does, your serums reach clean, receptive skin with nothing heavy in the way, so the ingredients can focus on your skin concern, and many clients notice results come faster from there.

What to expect:

  • Right away: skin feels hydrated, smooth, and refreshed.
  • The first few weeks: an adjustment period as skin finds its natural balance, often longer if you’re coming off heavy creams.
  • With consistent use: a brighter, more even-looking glow and smoother-looking texture.
Shunri recommends: Take a photo in natural light on day one, then compare at week 4 and week 8. Consistency matters more than adding more products.

Fresh formulas work best.

  • Keep products away from heat, direct sun, and steamy bathrooms.
  • Close bottles tightly after each use.
  • Vitamin C formulas (B,C,E + Ferulic Treatment, CE + Asiatic Treatment, and L-AA + Instant Eye Gel): store in the refrigerator (35–40°F) to keep every drop fresh and potent.
  • Brief warm temperatures during shipping are normal.
  • Use within 12 months of opening.
B,C,E + Ferulic Treatment, Shunly vitamin C serum

B,C,E + Ferulic Treatment

Your morning antioxidant serum, and the first step of daily defense.

Shunly B, C, E + Ferulic Treatment is a vitamin C antioxidant serum that helps defend skin against environmental stressors, brightens tone, and leaves skin looking clearer and more radiant. It combines vitamin C (L-ascorbic acid), vitamin E, and ferulic acid, a well-researched antioxidant trio.

How to use it in your morning routine: Shunri recommends this layering method:

  1. Cleanse your skin: Use a Shunly cleanser appropriate for your skin type.
  2. Restore pH balance: Mist on the Shunly pH-balancing toner to prep the skin. Vitamin C serums absorb best on pH-balanced skin.
  3. Apply B, C, E + Ferulic Treatment: Dispense 5–7 drops (or one full dropper) into your palm and apply evenly to the face, neck, and décolleté.
  4. Add hydration if needed: If your skin feels dry or tight, follow with a hydrating serum like SE + Apple Skin Stem Cells or B3, B5 + Peptides Hydra Gel.
  5. Finish with SPF: Apply Shunly mineral SPF to protect your skin and your results.

These three antioxidants work together to help defend skin against the environmental stressors behind visible aging.

The B, C, E + Ferulic Treatment is formulated with:

  • Vitamin C (L-Ascorbic Acid) – a potent antioxidant that helps brighten the complexion and defend against environmental stressors.
  • Vitamin E – a skin-conditioning antioxidant that works alongside vitamin C and helps skin feel soft and comfortable.
  • Ferulic Acid – a plant-based antioxidant that helps stabilize vitamins C and E so they stay effective.

Better Together

Combined, they form an antioxidant network that helps:

  • Defend against environmental stressors
  • Soften the look of premature aging (fine lines, dark spots, loss of firmness)
  • Keep skin looking healthy and resilient

Ferulic acid is well known for helping stabilize vitamins C and E, which is why this trio is a favorite in professional skincare. Antioxidants support your sunscreen; they never replace it.

Used every morning, it is your Prevention step, helping skin stay ahead of visible damage.

Suitable for all skin types, especially sensitive or sun-stressed skin.

Shunly B, C, E + Ferulic Treatment is formulated for all skin types, and it’s especially ideal for:

  • Normal to dry skin
  • Sensitive or redness-prone skin
  • Skin showing visible sun damage
  • Skin with uneven-looking tone
  • Skin prone to dark spots

Its antioxidant-rich formula helps to:

  • Keep skin feeling comfortable
  • Reduce visible signs of environmental damage
  • Improve radiance and calm the look of redness

Pro Tip: Professionals often use it before and after facials and peels to keep skin looking clear and calm. Use it every morning; its Primary SkinCareAct™ is PREVENTION.

A high-performance antioxidant concentration for visible results.

Shunly B, C, E + Ferulic Treatment features 20% L-Ascorbic Acid (vitamin C), a high-strength concentration chosen for strong antioxidant defense and visible improvement in tone, clarity, and texture.

Why 20% matters:

  • A 20% concentration offers strong antioxidant defense against environmental stressors that contribute to visible aging.
  • It works with vitamin E and ferulic acid as a powerful antioxidant trio.
  • It helps even out the look of skin tone for a brighter, more resilient-looking complexion.

Balanced for sensitive skin

High-strength vitamin C can feel intense on sensitive skin, so this formula is balanced with:

  • Soothing antioxidants
  • A pH-optimized base
  • And supportive ingredients like Ferulic Acid and Vitamin E

This makes it a comfortable option for skin prone to sensitivity or redness, with full antioxidant benefits.

Ideal for anyone who wants daily antioxidant defense against visible environmental aging. Always follow with SPF.
KA + Bio Lightening Treatment, Shunly brightening serum

KA + Bio Lightening Treatment

Hyaluronic acid is a moisture-binding ingredient that keeps skin hydrated and comfortable.

In Shunly KA + Bio Lightening Treatment, Hyaluronic Acid plays a key role in enhancing hydration and maintaining smooth, plump skin. This antioxidant gel serum absorbs quickly and hydrates while it works on the look of uneven tone, so skin stays soft, not dry.

How it works:

  • Hyaluronic acid is known for holding many times its own weight in water, acting like a magnet for moisture.
  • It draws water into the skin’s surface layers for a smoother, more supple feel.
  • Once applied, it forms a lightweight, invisible moisture veil that helps soften texture, reduce flakiness, and boost skin smoothness — without heaviness or residue.

For even better results: To lock in hydration and amplify the benefits of hyaluronic acid, follow with:

This pairing keeps skin balanced and hydrated while your brightening routine works.

A botanical brightening treatment suitable for all skin types — especially those with visible discoloration or sensitivity.

Shunly KA + Bio Lightening Treatment is a lightweight antioxidant-rich gel formulated for all skin types, including:

  • Normal, dry, oily, or combination skin
  • Sensitive or blemish-prone skin, including skin that shows: the look of redness / uneven skin tone / dark spots or post-blemish marks

Its botanically powered FUSION FORMULA® includes soothing, antioxidant, and clarifying ingredients that support:

  • A brighter, more even-toned appearance
  • Calming of visibly stressed or reactive skin
  • Gentle hydration and antioxidant protection

Pro Tip: Professionals also use it before and after facials and peels to help skin look calm, balanced, and more even-toned.

Ideal as part of a nighttime rotation for those managing visible pigmentation, redness, or dull skin.

Both products contain the same concentration of hyaluronic acid — designed to hydrate while each serves a different purpose.

While both the KA + Bio Lightening Treatment and the B3, B5 + Peptides Hydra Gel contain equal levels of hyaluronic acid, their textures and skin feel may differ slightly due to the other active ingredients included in each formula.

  • The viscosity (thickness or flow of the formula) is balanced in both products to ensure optimal absorption without heaviness.
  • KA + Bio Lightening Treatment offers added brightening and soothing benefits, while B3, B5 + Peptides Hydra Gel focuses on hydration, comfort, and peptides for a firmer look.

For best results:

To take brightening further, alternate nights with a vitamin A treatment: Vita A + C Treatment (normal to oily skin) or Vita A, E + Ceramides Treatment (normal to dry skin).

KA + Bio Lightening and B3, B5 + Peptides Hydra Gel can be layered or alternated in your nighttime rotation, depending on your skin’s needs.

IMPORTANT: Brightening and exfoliating ingredients can make skin more sensitive to the sun. Always apply Shunly SPF the next morning to protect your results and help prevent new dark spots.
AHA + Rapid Exfoliator, Shunly exfoliating serum

AHA + Rapid Exfoliator

Suitable for all skin types — especially those in need of resurfacing and renewal.

Shunly AHA + Rapid Exfoliator is formulated to deliver effective exfoliation using alpha hydroxy acids (AHAs), helping to smooth, clarify, and refresh the skin without harsh scrubbing. It’s ideal for:

  • Normal, dry, oily, or combination skin
  • Skin that appears dull, rough, or uneven in tone
  • Those experiencing buildup of dead skin cells or congestion
  • Prepping skin before professional facials and treatments

How it works:

This treatment gently lifts dead skin cells from the surface to:

  • Enhance absorption of serums and treatments
  • Refine skin texture and support a brighter appearance
  • Promote a smoother, more radiant complexion

Regular use keeps skin looking smooth and fresh and helps the rest of your routine work better.

IMPORTANT: Brightening and exfoliating ingredients can make skin more sensitive to the sun. Always apply Shunly SPF the next morning to protect your results and help prevent new dark spots.

Exfoliation and hydration — working in synergy for radiant skin.

While AHA + Rapid Exfoliator gently lifts dead skin cells to reveal fresher-looking skin, hyaluronic acid ensures that your skin doesn’t feel dry or stripped after exfoliation.

As AHAs help resurface the outermost layer, hyaluronic acid helps:

  • Replenish moisture in the freshly exfoliated skin.
  • Keep skin feeling comfortable.
  • Leave the skin feeling soft, plump, and hydrated.

This combination smooths texture and hydrates at the same time, for a brighter, smoother, healthier-looking complexion.

Ideal for those seeking both exfoliation and hydration in one step — especially for dull or dehydrated skin.

Best used at night. Its Primary SkinCareAct™ is CORRECTION.

The AHA + Rapid Exfoliator lifts dead skin cells to smooth texture and help your other products absorb better. Use it in your evening routine, alternating with other serums, just as a professional would.

How to apply:

  1. Cleanse with your Shunly cleanser
  2. Balance pH with the Shunly pH-balancing toner
  3. Apply AHA + Rapid Exfoliator on designated nights
  4. On alternate evenings, use other targeted treatments such as KA + Bio Lightening, SE + Apple Skin Stem Cells, or B3, B5 + Peptides Hydra Gel

Sample Weekly Nighttime Rotation:

Day / Treatment Focus / Recommended Products

  • Monday: Exfoliate – AHA + Rapid Exfoliator
  • Tuesday: Hydrate + firm – B3, B5 + Peptides Hydra Gel
  • Wednesday: Brighten – KA + Bio Lightening Treatment
  • Thursday: Revitalize – SE + Apple Skin Stem Cells
  • Friday: Vitamin A – Vita A + C or Vita A, E + Ceramides Treatment
  • Saturday: Exfoliate – AHA + Rapid Exfoliator
  • Sunday: Hydrate + firm – B3, B5 + Peptides Hydra Gel, and so on.

Always apply SPF the following morning — exfoliated skin is more sensitive to UV exposure. Adjust frequency based on your skin’s sensitivity or professional advice.

Alternating high-performance serums throughout the week gives your skin full-spectrum care: exfoliate, brighten, hydrate, and protect.

No — this is a leave-on exfoliating treatment.

Unlike traditional scrubs or wash-off exfoliants, Shunly AHA + Rapid Exfoliator is a concentrated leave-on serum designed to work while remaining on the skin. It works by:

  • Gently exfoliating dead skin cells.
  • Revealing smoother, fresher-looking skin.
  • Enhancing hydration with hyaluronic acid and soothing actives
  • Preparing the skin to better absorb follow-up treatments.

There is no need to rinse off the product — doing so would remove the actives before they’ve had a chance to deliver full benefits.

For best results, use 2–3 times per week, alternating with other Shunly serums as part of your nighttime rotation.

B3, B5 + Peptides Hydra Gel, Shunly hydrating serum

B3, B5 + Peptides Hydra Gel

Lasting hydration with a calm, plump finish.

In the B3, B5 + Peptides Hydra Gel, Hyaluronic Acid delivers long-lasting hydration by drawing water into the skin’s surface layers. This gel hydrates, calms, and leaves skin looking plumper, with niacinamide (B3), panthenol (B5), and peptides.

What Hyaluronic Acid does in this formula:

  • Acts like a moisture magnet, helping your skin retain water where it needs it most.
  • Supports a visibly smoother, dewier texture.
  • Helps reduce the appearance of fine lines caused by dehydration.
  • Works alongside the gel’s vitamins and peptides

For best results:

Follow with Shunly Botanical-C + Peptides Gel Lotion for extra hydration and peptides, especially if your skin feels dry or you’ve just had a professional treatment.

Ideal for all skin types, including sensitive or post-treatment skin, when hydration, comfort, and a calm, clear look are the goal.

A versatile hydrating and soothing gel for all skin types — especially sensitive, blemish-prone, or post-facial skin.

B3, B5 + Peptides Hydra Gel is designed for all skin types, but it is particularly well-suited for:

  • Oily or blemish-prone skin.
  • Dehydrated or stressed skin.
  • Skin after professional facials or treatments.
  • Skin that needs lasting, lightweight hydration.

Why it works:

  • Vitamin B3 (Niacinamide) helps skin look clearer and calms the look of redness.
  • Vitamin B5 (Panthenol) soothes and conditions the skin.
  • Peptides support a firmer, smoother look.
  • Hyaluronic Acid helps hold moisture in, so skin stays hydrated.

Together, these ingredients make this gel ideal for anyone needing hydration, calming, and post-procedure support with a light, non-greasy finish.

Use daily, especially after exfoliation, brightening, or corrective treatments to promote a balanced, smooth, and radiant complexion.

Yes. This gel is formulated with a high-performance level of hyaluronic acid for lasting hydration.

B3, B5 + Peptides Hydra Gel uses a level of hyaluronic acid chosen to:

  • Attract and retain moisture in the skin.
  • Create a smooth, viscous texture that glides easily without heaviness
  • Work with vitamin B5 (panthenol) for soft, comfortable, hydrated skin.

This optimal blend helps improve hydration, softness, and skin resilience while making the gel fast-absorbing and suitable for all skin types — including oily, sensitive, and blemish-prone skin.

Ideal as a daily hydration step or post-treatment support serum.
Vita A + C Treatment, Shunly vitamin A serum

Vita A + C Treatment

Vitamin A (the retinoid family) is one of the most well-researched skincare ingredients for smoother, renewed-looking skin.

Adding vitamin A to your evening routine helps soften the look of environmental damage and keeps your complexion smooth and youthful-looking.

Why vitamin A matters:

  • Helps fade the look of dark spots and smooth uneven texture.
  • Reduces the appearance of fine lines, wrinkles, and enlarged pores.
  • Helps skin look firmer, clearer, and more radiant over time.
  • Softens visible signs of sun-related aging.
  • Enhances absorption of other corrective or hydrating products.

Shunly FUSION FORMULA® vitamin A treatments are designed for visible results with a comfortable feel:

How to use:

  • Apply only at night, after your pH-balancing toner.
  • Start 2–3 nights per week, then increase as tolerated.
  • Always follow with Shunly SPF the next morning.
  • Avoid combining with exfoliants or brightening actives on the same night
Vitamin A is not just for correction: it’s a long-term investment in smoother, healthier-looking skin.

Vita A + C Treatment is best for normal to oily, uneven, or blemish-prone skin. It pairs vitamin A with vitamin C to refine texture, fade the look of dark spots, and add antioxidant support.

Vita A, E + Ceramides Treatment is ideal for dry, sensitive, or mature skin. It pairs vitamin A with vitamin E and ceramides to help skin hold moisture, soften the look of wrinkles, and feel comfortable.

Both are nighttime treatments whose Primary SkinCareAct™ is CORRECTION.

Start by using 2–3 times per week in the evening. Once your skin builds tolerance, you can increase to every other night or nightly, depending on how your skin responds.

If you experience dryness or irritation, reduce frequency and pair with hydrating treatments like SE + Apple Skin Stem Cells or B3, B5 + Peptides Hydra Gel.

When using a vitamin A product like Vita A + C Treatment or Vita A, E + Ceramides Treatment, avoid the following:

Facial waxing and retinol don’t mix. Vitamin A makes the skin’s surface more delicate, so wax can lift the skin itself, not just the hair, especially around the brow, upper lip, or cheek area.

How long before facial waxing should you stop?

  1. Retinol and vitamin A products, including Shunly vitamin A treatments: stop at least 3 weeks before any facial waxing.
  2. Prescription-strength retinoids (e.g., tretinoin, Retin-A, adapalene, tazarotene): stop at least 3–4 weeks before waxing (or as directed by your provider).
  3. Oral isotretinoin (Accutane): no facial waxing during treatment or for at least 6 months after your last dose.

Tanning beds or too much sun: Vitamin A can increase sun sensitivity. Always use Shunly SPF daily.

Always inform your skincare or waxing provider of any retinol or prescription treatments to ensure safe services.
Zn20 + SPF40 Light Moisturizer, Shunly mineral sunscreen

Zn20 + SPF40 Light Moisturizer

Zn20 + SPF40 Light Moisturizer is a mineral sunscreen made with 20% zinc oxide for broad-spectrum UVA and UVB protection, with a lightweight feel suited to sensitive skin.

Mineral protection: Zinc oxide is one of only two sunscreen actives the FDA has proposed as generally recognized as safe and effective (GRASE). It covers both UVA and UVB and is well suited to sensitive skin.

Comfortable for sensitive skin: Zinc oxide is known for being gentle, which makes this formula a favorite for sensitive, redness-prone, and blemish-prone skin.

Thoughtful formula: Made without chemical sunscreen filters, parabens, PABA, synthetic fragrance, or dyes. Vegan, cruelty-free, and suitable for all skin types, including post-facial skin.

Creamy, wearable texture: The smooth, lightweight cream blends easily with minimal white cast, making it ideal for daily wear, even under makeup.

For the whole family: Gentle enough for mature skin and teens. For children under 6 months, ask a doctor.

Zn20 + SPF40 Light Moisturizer: daily mineral protection with a comfortable, lightweight feel.

Ultraviolet (UV) light is a form of invisible radiation energy emitted by the sun and artificial sources like tanning lamps. It exists just beyond the violet end of the visible light spectrum and is classified into three main types:

UVA (long-wave) – Penetrates deeply into the skin and contributes to skin aging and wrinkling.

UVB (short-wave) – Affects the outer skin layers and is responsible for sunburn and direct DNA damage.

UVC – The most dangerous form, but fortunately blocked by the Earth’s ozone layer and doesn’t reach the ground.

Both UVA and UVB rays reach the earth’s surface and contribute to sunburn, premature skin aging, dark spots, and skin cancer risk.

Artificial sources like tanning beds emit UVA and/or UVB rays, and they impact the skin in the same way as natural sunlight, making protection essential even indoors or during non-sunlight exposure.

Consistent use of physical sun protection, such as Zn20 + SPF40 Light Moisturizer, helps protect skin from UV damage.

Both UVA and UVB rays are ultraviolet radiation from the sun, but they affect the skin in different ways:

UVA (Aging Rays)

  • Penetrates deep into the dermis (the skin’s thickest layer).
  •  Causes long-term skin damage, including premature aging, wrinkles, and loss of elasticity.
  • Can penetrate through windows and clouds.
  • Contributes to skin cancer risk.
  •  Present year-round and throughout the day, even in winter

UVB (Burning Rays)

  • Affects the epidermis, the outermost skin layer.
  • Main cause of sunburn and redness.
  • Directly damages DNA, increasing the risk of skin cancer.
  • Intensity varies by season, location, and time of day.
  • Most harmful between 10 AM and 2 PM
Protection from both UVA and UVB is essential for skin health. Zn20 + SPF40 Light Moisturizer offers broad-spectrum protection with 20% zinc oxide to help protect against both.

Sunscreen filters work in different ways and feel different on the skin.

Physical (Mineral) Sunscreens – Zinc Oxide & Titanium Dioxide

  • Sit on the skin’s surface and help block UVA and UVB rays.
  • Less likely to irritate sensitive skin.
  • More stable in sunlight (do not degrade easily).
  • Offer broad-spectrum protection against both aging (UVA) and burning (UVB) rays.
  • A favorite for sensitive, redness-prone, and post-facial skin.

Chemical Sunscreens – Avobenzone, Oxybenzone, Octinoxate, etc.

  • Absorb UV rays and convert them to heat.
  • Some filters may degrade in sunlight unless stabilized.
  • May irritate some sensitive skin types.
Shunly Zn20 + SPF40 Light Moisturizer is formulated with 20% zinc oxide for broad-spectrum mineral protection with a comfortable, lightweight feel.

No sunscreen can block 100% of the sun’s rays, but a well-formulated broad-spectrum sunscreen—like those containing Zinc Oxide—can greatly reduce the effects of both UVA and UVB rays.

Understanding Sun Rays:

  • UVB rays are primarily responsible for sunburn and surface-level skin damage.
  • UVA rays penetrate deeper into the skin, accelerating photoaging and contributing to skin cancer.
  • Infrared rays (IR) and visible light (HEV/blue light) can also affect the skin, especially in individuals prone to hyperpigmentation or melasma.

What Broad-Spectrum Sunscreen Does:

  • Blocks or absorbs UVA & UVB rays to help prevent sunburn and early skin aging caused by the sun.
  • Mineral filters like Zinc Oxide provide mineral protection from the surface of the skin.
  • Chemical filters absorb UV rays, but may not cover the full spectrum unless properly formulated.

Even with a high SPF, no sunscreen is a complete shield.

Pro Tip: For broad-spectrum protection, check that the label specifies UVA and UVB coverage. Not all sunscreens do. Look for active mineral ingredients like Zinc Oxide and Titanium Dioxide, which work from the skin’s surface.

Shunly FUSION FORMULA® Zn20 + SPF40 Light Moisturizer is formulated with 20% zinc oxide for broad-spectrum protection. This lightweight mineral sunscreen suits all skin types, including sensitive and redness-prone skin.
