If your 13 year old dislikes the mole and would like it removed, it can be done quite easily in the office within 10 minutes. A local anesthetic is required, the mole is excised and sent to the lab, and it takes about 10 to 14 days to heal. The cosmetic result is usually excellent. Avoid sun on the fresh skin to prevent pigmentation.
It is very easy to remove moles from the eyebrow area on a young individual. Cosmetically speaking, the results are excellent. The procedure itself is not very involved and can be done in an office with local anesthesia. I recommend you consult a board-certified dermatologist or facial plastic surgeon and make sure that whoever removes it (if you choose to), he or she then sends the mole to the pathologist to be checked.
