I've always had pretty bad acne, but one of my friends recommended this mask for me. (Freeman feeling beautiful avocado and oatmeal clay mask.) I've been using it since May, and my skin has never looked better!
I have fairly sensitive skin (my skin is so red and usually burns after being exposed to too much chlorine-and of course, I swim in a not-saltwater-pool. Benzoyl peroxide is not my friend either), but this has never caused me any problems. If your skin is extremely sensitive, I probably would not recommend it simply because it is a mask, and it may irritate your skin more than a cleanser would, but other than that, it's one of my favorite beauty products.
