had it removed 6 months ago, im 31 now, noticed it ( i think) about a year before but thought it was a blemish. go to a dermotologist. i did go in the sun and tanning bed a lot...no more tanning bed and sun screen when outside. i had it on my face so i got M.O.S.E. method, more expensive but less scar and more likely to get it on first operation.
