Jen and Tonic 0 Share Posted November 5, 2007 I don't know whether this has been posted before, but there is a list online that rates many common ingredients in terms of comedogenicity and irritancy. Many of these chemicals are used in products that claim to treat acne, and could in fact be causing acne and irritation. So grab all your products and check the ingedients against this list! If your acne is mild but persistent, all those OTC treatments, or even more likely a "non-comedogenic" make-up, could very well be the cause.[post=http://zerozits.com/Articles/acnedetect.htm]Check it out!
