    This is one of my favorite products. I use it in the morning and my skin feels soft and not overly dry or oily though out the day.

    This 20% vitamin C serum are my favorite product in the morning. I no longer need additional antioxidant face cream and eye cream. With this serum, my skin does not feel dry or oily during the day like I did when I used the face cream before. It clear my skin by lightening my hyper pigmentation as we as fine lines and wrinkles around my forehead and under my eyes area. I don`t have to spend additional cost to buy face cream or eye cream but Zn20+spf40 light moisturizer sunscreen. Simple steps but yet give my skin stay healthier than ever.

    For years I had dry skin combined with acne. I went back and forth trying cleansers/moisturizers for oily skin in an attempt to clear up the acne and cleansers/moisturizers for dry skin in an attempt to hydrate – nothing worked and most products only made things worse. After spending hundreds if not thousands of dollars on drug store, department store and special order products I finally gave Shunly product a try because one of my friend told me about this brand name that I never heard about it before – IT WORKED!!!! My skin is now acne free, moisturized and healthy! Plus Shunly product doesn’t have paraben and no tested in animals as well as all the acne products are free from oil. It was little difficult to pick which product to use since I had dry skin with acne. I sent email to betterskin@shunlyskincare.com asked for help and they were so nice and sent me all the samples that will help my dry as well as my acne. All the samples lasted about a week and after two days of used, my skin felt different right away. I never thought I will find any product line in the market that will help my skin condition with dry and acne the same time. I ordered the whole skin system after a week and my skin felt beautiful ever. I just love it. Thanks to my friend.
