I am loving cosdna right now. It's a website that tells you if a product contains comedogenic ingredients. My skin was so clogged, and using cosdna I discovered that a ton of the products I was putting on my skin had potentially pore clogging ingredients. I stopped using everything on my skin except my cleanser and my clogs are so much better! I seriously thought my clogs were hormonal in nature, but now I think they are a reaction to all the products I've been using. I hope someone else finds this helpful
