I can proudly say that I never had any skin problems while I was in high school, or in college. But I wish I can say that right now ... since after I gave birth my face started acting up! I have heard reviews about skin id, but haven't actually used it. Yet. There are conflicting reviews about the product, but I guess that's just because everyone of us is different and so would also react differently to the product (even if it does say that it is a 'personalized acne treatment').
But who knows? I just might try it, one of these days. ;P
