Is There a Certain Age when Starting Retin A Would No Longer Be Helpful?

As long as your skin is alive and metabolically active, Retin-A can have beneficial effects on skin metabolism, exfoliation, softness, line or wrinkle reduction, and stimulation of collagen and elastic fiber growth. At advanced age, we all have cumulative sun damage, loss of collagen and elasticity, and reduced vascularity in our skin (especially sun-exposed skin), and Retin-A helps all of these things!

Retin-A will have beneficial effects on your skin regardless of your age.  It will result in smoother skin, reduction in fine lines, and help to build collagen.  

A maitainance program of Retin A is always helpfull.

Once you reach the desired results then you can go on a maitainance program of applying Retin A every other day, or every twice a week..

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.
