I'm 36 & always looked young for my age, but recently noticed fine lines under the surface of my whole face so.. I started using Tretinoin - Retino A 0.025%. The skin around my eyes hasn't tolerated it well. Swelled up, dried, flaked and new deep, crepey wrinkles appeared (see pic) They seem to be on a top layer of skin but I now look older than my gran! In addition, my skin is now sagging too. Is this temporary? If I stop using the Retin A will my skin go back to how it was before I used it?
