I'm on my peeling week. My new peel hero is the Alpha H Beauty Sleep Power Peel. It contains 15% glycolic acid and 0.5% retinol. The suggestion is to use it twice weekly. I've tried that. But I see more result using it one full week straight monthly. Like how I used the Sunday Riley Good Genes. The problem is, after using it for one full week my skin is very dry, so I always layer it with a nice serum oil and balm to give my skin hydration.
