Why is my face burning, peeling, tight, and glossy when using Retin A (Tretinoin) .1% every evening?

Tretinoin is an excellent topical, however it can be very irritating. I always start my patients with the .04% to avoid such irritation. My first suggestion would be to get a lower percentage. If that is not possible then you can apply your .01% Tretinoin every other night or every two nights and gradually work your way to every night once your skin has become accustomed to it. You can also apply a moisturizer on top of the Tretinoin to help with the dry tight feeling. The peeling is a good thing; the Tretinoin is exfoliating the top dead layer of skin, this will eventually subside. As far as the burning sensation after sunblock application this does sometimes happen when the skin is peeling, try applying a moisturizer before your sunscreen to see if that helps.
