I have had a small beauty mark mole on my face atleast since I was a toddler. It s not much bigger than the tip of a pen. The other day it seemed to have developed a pimple under it. I used a astringent on it and the swelling went down. However the area dried up and began to peel. The brown layer peeled off. Now there s just the same raised area with no color to it. I plan on getting it looked at, but what could this be?
