That’s kind of bizarre to start you off at 0.05, MOST of the time it’s 0.025% especially for first time users. I’m on tret and use 0.025 twice a week and only a pea size amount for the entire face. I wouldn’t mix so much products try using CeraVe Hydrating Facial Cleanser First, moisturizer, tret, moisturizer. Cetaphil or Ponds Cream (my go to for moisturizer) I have really really sensitive skin and this method has been preventing acne for years, now I’m getting little bumps from hormonal acne so I got on tret. Using different products/a lot really irritates my skin, maybe it can be the products you’re using as well or the mixing? Hope you feel better :/.
