I have these on my upper arms,thighs,and calves.
Research has led me to it possibly being keratosis pilaris, except,the problem is,isn't that usually raised? These seem to be under the skin. They don't really feel like bumps.
._. I did a little more research and it indeed is KP.
A hereditary skin disorder.
T_T There is no cure. Just buy one of those scrubby shower brushes,and everyday scrub the **** out of it then use a good lotion. It will come and go your whole life,but treating it like that usually lessens its appearance for me.
As does tanning. And if you don't want the damage,buy one of those gradual tanning lotions by Vaseline or Olay. ^^ A lot of people have this problem.
