Not sure if this is where I should post this. I'm a22 year old guy, 3 years ago I noticed I had 7 ''suspicious marks'' around my body. I figured they were all calm marks. 4/7 of them are of size and 6/7 of them are very very faint, all of which are atypical. I went to a derm and she has now checked me twice, she thinks 1-2 of them could be post-inflammatory pigmentation or damaged skin - yet I've never heard of that before. My eyes and all have been checked thoroughly, I have no other symptoms at all. Why do I have these birthmarks - should I let this go or could this be related to something else. thankyou
