In high school, I had a major breakout one day. I left a heavy layer of oxy on my skin and it gave me a chemical burn. I have sensitive skin, so I don't leave any gels or creams on it for more then a few hours at at time. Just be careful.What will happen if i leave 10% benzoyl peroxide wash on my face?
