Im 16 years old and im not sexually active nor have i ever engaged in intercourse. For a while now I've noticed a red rash like mark by corner of my lower lip. Im fairly certain it isnt a rash because it does not itch, but it is very slightly bumpy similar to acne. I have been using face cleasning products and acne clearing products to get rid of at least some of my acne and I'm not sure if this would be the problem? Or what the mark is.
