Question: reaction to benzoyl peroxide


 rain - Mon Mar 03, 2008 5:35 pm

I used proactive 2x on thursday and had a reaction. My entire afce and neck broke out in a rash , red slight swollen with a million tiny bumps everywhere. Benedryl didn't help. Now it has improved a bit the swelling and reddness are gone but the bumps are still there. My face feels like sandpaper. What can i do? with it get better? how long?

User avatar Hello,
You will probably have to just wait it out. The antihistamines are the best thing to do (adults can take 50 mg. Benedryl at a time). You may respond with some cortisone too but it will probably resolve in a few days.

In the future you should avoid benzoyl peroxide. You might want to see a dermatologist for a prescription to fight the acne. Salicylic acid is also used in acne treatments but if you try it, do a test on a small patch of skin first.

Good luck.
