What is organic benzoyl peroxide?

I checked the page, to see what is new in it, after switching to all natural cosmetics for 2 months, I had enough of the acne, after few uses of Proactive, it is really under control, but I don't really like ingradients in it, all chemicals. So I see this and makes me wonder if I would be really switching to something better. Also I was using Burt's Bees Tinted facial Moisturizer as a foundation, and it is just too oily and waxy, I actually think it was worsening my acne. So went back to comercial stuff. Anyone out there with any luck with foundations. Also Aubrey Organics Translucent base doesn't work for me as foundation, doesn't cover all imperfections, and wears off after 3 hours. Tweet
