Hello, I have Keratosis pilaris on the backs of my arms, thighs and butt. It's pretty bad...a lot of red, inflamed follicles (sp?). I went online and saw products were available to help the appearance but they were so expensive, and the products do not cure, they just treat as you use them. I was just wondering if there was something less expensive I could used, or do, like exfoliation? It's a little embarrassing, people tend to confused it with acne....
