Benzoyl peroxide / clindamycin
"I've used it for a week and first three days were ok  besides the peeling off the skin, it was moderate and not ichy a lot;  so I gave it a chance. After a week or so one morning woke up with competely irritated skin, red, it was like  I had laser procedure.  Didn't use it the following night hoping redness and itchiness would go for good but following day was even worse. Puffy red, itchy and irritated skin, dry like a raisin..so and as it's weekend have to stay calm till tomorrow's doctor's appointment hoping it will all get cured.
Really seems like allergy or chemical burnt. I really hope it will be healed.  I really advise it to use on small parts of the acne affected places just to give it a try."
