I'm a newbie on this site.
I'm sixteen, and my Keratosis Pilaris developed when I turned fifteen. I have KP on the back of my arms only, and my case is considerably minor. I've heard from sources that KP goes away in one's twenties. I'm hoping this is all just a normal thing for puberty/whatever considering a lot of people have it. Because I developed this just last year, do you guys think it'll go away?

To help lessen the redness I apply baby oil in the shower and I rub a lavender soap on top. It greatly improves the appearance.
