Stop using benzoyl peroxide now since it seems like you could be allergic to it (some people are!) Feel free to put on hydrocortisone cream on your face for a couple of days so that you get rid of the burn like situation (the BP has burned your skin and now it's peeling just like from a sunburn, hydrocortisone is a good emergency remedy for this)If you ever want to use benzoyl peroxide again, I would suggest a much milder product. Acne.Org has a good 2,5% benzoyl peroxide gel. It works just as good without so severe side effects. Personally, I'm sensitive to even it, and I need to start with very thin layers every other night, and then ramp it up slowly. This way your skin can get used to it, unless your very allergic to it. So be carefull! You can go to a doctor and ask for some clindamycin lotion (such as dalacin T). It's an antibiotic lotion that rarely causes bad reactions while it's still effective against inflammatory acne. Best skin care wishes.
