Cosmetic mole removal can cost you quite a bit if you are having it done by a doctor. This is not usually covered by insurances because it is cosmetic. That leaves you footing the entire bill.
Some of these treatments may also have side-effects. Redness, swelling, crusts, and bruising (especially with laser treatment) is always possible. These can leave people even more frustrated because they are trying to improve their appearance not make it look worse.
