As I've said on my previous post, everybody have different skin reaction on every beauty products. That only proves when my two identical twin daughter have different reaction on Proactiv.
So it doesn't matter how expensive or famous the skin care products that you are using, it is about trying to find a skin care product that works for you. I know that it can be expensive to keep trying new product until you find the right one. But once you find the right skin care products, try to stick with it and don't be persuaded buy the advertsing strategy of other new expensive products.
