H.F.
It could be the benzl peroxide (sp?) I used to use products containing it all the time (I've had acne for 20 years, very depressing) but then I developed an allergy to it and it made my eyes itchy and puffy, plus it caused a rash on my face (delightful) so now I can only use products without benzl peroxide in them. In my experience Proactive is much better at marekting thier product than acctually curing acne. But then again I've never found a cure (OTC or prescription) so it's probably my stupid skin :(
