Hi, I have a small red dot in my hairline. I ve had this once or twice before, and it s gone away. This one has been there for about 3 weeks now. First thought would be acne/ pimples , but it is a lot brighter of a red than any other pimples I get. It is right next to an old one that is now brown, almost like a small mole/ freckle . I do not have bad acne, and when I do it s not in my hairline like this. What could this be?
