Which are the main vitamins which support beautiful skin ? dr perricone?

Skin vitamins: Healthy skin requires a variety of vitamins to keep it resilient; specifically, vitamins a, vitamin e, vitamin c, and vitamin d. Furthermore, vitamins e and c (found in citrus fruits and vegetables) are the simplest form of antioxidant. Antioxidants may help prevent skin damage from free radicals, a dangerously mutant form of oxygen that can cause wrinkles and other damage.

Healthy diet: A healthy diet supports beautiful skin. Eat healthy and you won't need any vitamin supplements at all - certainly not the exhorbitantly expensive ones sold by dr. Perricone and his ilk.
