Oxidation process and free radicals in the skin.
My experiment shows the soft insides of apple which was exposure to the oxygen in the air for half an hour. One half become oxidized causing them break down and turned them brown and the another is no changed because was applied with lemon juice full of Vitamin C.
Very similar process shows our skin. To prevent such as major process we suggest using antioxidants to help to fight with the oxidation.
Antioxidants are frequently added to cosmetic products. Common antioxidants:
Vitamin C, Vit E, Vit A, folic acid, and beta-carotene.
The top Antioxidant creams recommended by dermatologist David McDaniel:
Elizabeth Arden Prevage Face Advanced Anti-Aging Serum
Neutrogena Ageless Intensives Anti-Wrinkle Serum
Revaléskin Night Cream
Vivité Daily Antioxidant Facial Serum
Skinceuticals Phloretin Cf Gel
Dr. Brandt Lineless Cream
All of them are well designed formulation for both preventing damage and softening fine lines, he says.
