and quite frustrated. Since I was about 9 I have had Keratosis pilaris alba that affects my upper arms and cheeks. Both my parents had good skin as children, so I do not know where I would have obtained iot since it is genetic. It has been frustrating since I have no idea how to treat it, but I have found that shaving my upper arms sometimes makes the bumps less "bumpy". I have tried a lotion called Lac-Hydrin, but it doesn't seem to help. My brother who is 19 had it at my age, but his has calmed down quiet a bit. I just want to know what I can do to treat it.
