As of August, I'm allergic to benzoyl peroxide, as evidenced by extreme redness and irritation with the smallest amount and crusting and flaking that refuses to go away, no matter what kind of oils or how much moisturizer (CeraVe) I use or if I seal it with vitamin e oil or if I use a cleanser for extremely dry skin (the SkinMedica one that's for after medical skin treatments). I accidentally used a teensy bit too much more than two weeks ago and I'm still dealing with the crusting and flaking. Any suggestions?
