Tretinoin: Vitamin a acid (tretinoin [retin a, renova]): this ingredient, available by prescription, has the longest track record of success in treating aging skin and fine lines. Creams containing tretinoin must be used on an ongoing basis. They may produce redness and peeling at first, but discomfort can be minimized by lowering the cream's concentration or applying it less often until the skin gets use to.
