What to do if i have a small birthmark, 1/4 of an eraser tip. how can i get rid of it?

Depends on variables: Depending on the type of mark, one this size is often removed surgically, with the material sent for analysis if there were any features that suggested problem. Depending on the location you might see your pcp, a surgeon, a dermatologist or plastic surgeon.Sometimes a call to the office can find out.A dermatologist might remove it at an initial visit.
