I have just finished 2 bottles, and this is my third bottle. Its special feature is to help. The skin is healthy and helps to heal scars effectively. It states that it is lightweight, and it is easy to penetrate the skin. Some time ago I used an American Vitamin C brand, but it is not good because my face is sensitive, do not use a serum with a high concentration of vitamin C, it is not good, it causes my face very acne until I find The reason for this is seen, and I really recommend that you all use this serum because it has a mild concentration, sensitive face.
