Any peel-off masks good 4 oily, coarse, ruddy, shiny, flaky skin w very visible pores&occasional mild acne? What about niacinamide? Tretinoin? What makeup??

Glycolic, tretinoin. Glycolic acid face masks can be helpful in situations like yours for the acne, blackhead exenteration and exfoliation, but only has short term results. Tretinoin , if your skin is not too sensitive for it, is an effective option for reversal and prevention of acne as well as the uv damage reversal and reducing wrinkle progression, but takes a few months. Niacinamide has mixed results.
