Retin-A .1 Every Day Still Has No Effect, What Can I Do?

Peeling is not a sign that a topical retinoid is working, rather it indicates that the skin is experiencing an irritant dermatitis.  In my patients that experience peeling while on a topical retinoid, I recommend either reducing the quantity of cream/gel applied or using the retinoid every other night until their skin develops more tolerability to the product.

Your Retin-A is still working for you even though you are not peeling.  Continue using it and sunscreen.

You could consider in-office treatments that would boost the effects of your creams.  Chemical peels, microdermabrasion, IPL, Thermage and laser treatments stimulate more collagen and may give you the effect you desire.

Consult a board certified dermatologist or plastic surgeon to see which treatments might be suitable for you.

What strength of Retin-A are you currently using? And how many days a week do you use it and how is it applied?  That is great that you are not experiencing any irritation or peeling, Retin-A will still work without those side effects, but make sure to wear SPF and hydrate on a daily basis to avoid any complications.
