As we get older, time and cumulative sun exposure lead to the signs of skin aging, which include fine lines, color change, and rougher texture. Retin-A is a synthetic Vitamin A cream that can help (slowly) with all of these signs over time. Adults of any age can potentially use Retin-A for aging (although it should be avoided in women who are or might be pregnant). As we get older, we often get deeper lines and wrinkles, which Retin-A will not help very much. Even so, it can still help with skin coloration and texture. There is no upper limit to the age at which Retin-A can be useful. Consult a board-certified dermatologist to discuss Retin-A alone or in conjunction with other treatments for the signs of aging.
