Tretinoin 1%

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 skin’s appearance even ten years after starting treatment. A study in the Archives of Dermatology, May 1996, shows that 0.1% tretinoin significantly improves the appearance of early stretch marks. Tretinoin works best on stretch marks that are new or enlarging.
