Do I really need to use tretinoin to delay fine lines? It is making my skin extremely sensitive, and it makes flushing worse. My skin has been flaking off, and I now have so much acne. I am able to control my acne with benzoyl peroxide. Would regular radiolfrequency microneedling treatments help delay fine lines and wrinkles? I also have a few old acne scars on my face. Will microneedling clear up the scars?
