How can i get rid of dark marks from mosiquito bite i cant get rid of ?

TakeAPeekForAWeek: Some people get dark marks from small traumas to the skin, like small punctures or insect bites. It's a bummer 'cause it looks like you're a popper or something. You'll have to wait for the healing (actually, over-healing) to subside and make sure there's no active infection. Then apply a mild topical steroid (hydrocortisone 1%) three to four times a day. If that fails, best to see a dermatologist
