This problem is usually hereditary and can be fixed
Your dermatologist can give you a cream to get rid of them. The generic name for it is "Clobetasol." Strydex or any other pimple cream will NOT work.
Clobetasol will take some time to work. You will notive that the area will no longer be bumoy after about 1 week. But the red dots will remain for sometime. One noticable side effect is that the area where you apply the cream will whiten considerably.
I had the same problem and got rid of it. Go to your dermatologist and get a prescirption. It is definetely worth it.
