How much would it cost to remove 3 protruding moles on my face. any estimate will do. thanks in advance?

It depends: Most dermatologists & facial surgeons will estimate the cost for you in the office depending on whether insurance will cover part or all of the procedure. For benign dermal nevi, a shave removal may suffice, but often we confirm with pathology reading. In my area, the first removal costs ~$300 all in including pathology (more if stitches are used), and subsequent removals are a bit discounted.
