Red marks won't go away
I got a spot on my forehead over a year ago, seemed like just a normal spot like the ones I normally get. My spots always disappear completely within a week, but for some reason I still have a red mark from this spot. It's not a spot any more from what I can tell, just a red mark. Then two weeks ago I got another spot next to it and the same thing seems to have happened, there is a red mark and I don't think it will go away.
Why is this and what can I do to get rid of them?
