Are you wearing dark pants? Are you darker complected? Maybe a good exfoliator would help.

i think it might be some form of pigmentation you probly do wash and it dosent come off right i dont think exfoliation would work if thats the case you mite need to see a dermatoligist i think thats the one anyway good luck.
Yes a skin specialist might be able to tell you, truthfully most people dont look like magazine models do down there. That is all air brushed in to look nice. Notice how no one has a flaw!
