Retin-A

Retin-A (Tretinoin) skin preparations are a family of drugs all similar to Vitamin A. In general, tretinoin gels are stronger than tretinoin creams because the medicine penetrates better when in a gel form. Tretinoin is used to treat acne and aged, sun damaged skin. Tretinoin works best when used in combination with alpha hydroxyacid preparations. If used over a period of years, tretinoin will continue to reverse aging of the skin and can continue improving the skins appearance even ten years after starting treatment.
