I am 42 started a Retin A (Tretinoin) .1% every night. It's leaving my face very tight, my forehead and nose have a glossy look, and peeling a lot. When I apply Aveeno 70% uva/uvb sunblock my face feels like it's on fire. What should I do differently? I don't want to stop using it because it is getting rid of wrinkles and sun/age spots.
