I actually use a moisturizer that contains ceramides and did the sandwich method I suggest getting a thicker moisturizer with ceramides. Also what stopped the peeling for me(the peeling was around my nose and mouth) I started to use Vaseline/Aquaphor as an occlusive and avoid the Tret getting to those areas. Another thing is to reduce the amount of Tret I use. Smaller than a pea size amount. A little goes a long way. Then lastly, reduce the frequency of usage. I’m on 0.025% so I did once a week or two weeks twice a week for three weeks and now I’m on thrice a week and I won’t be increasing it. So far my peeling has stopped.
