I see this every day. Some parents and kids are really freaked out by it. Most of the population has it. It may have an inherited component, and run in families. Many are unaware they are walking around with it. By and large, this is a painless phenomena, but causes a fair amount of consternation. It has a horrible, bad diagnosis-sounding name, and it is no big deal. I am talking about hyperkeratosis pilaris, of course.
