While they can turn up anywhere, skin tags tend to appear where there is frequent friction, such as the neck, breasts, groin, and underarms. Ultimately, there is no evidence that skin tags will lead to any serious skin condition: They’re mostly an aesthetic annoyance. Regardless, most dermatologists encourage you to have them checked out—and removed, if you want. The only link to danger is from one study from the Indian Journal of Dermatology, which suggested that skin tags may be a sign of underlying heart issues. You could get your heart checked out, but the one research connection shouldn’t concern anyone too much.
As noted above, it is possible to remove a mole by "shaving" it off. Shaving a mole offers the advantage of not having sutures, but has the clear disadvantage that if the mole extends beneath the surface of the skin, as most do, it will predictably grow back, usually within weeks of being shaved off. It is for this reason that Dr. Rapaport usually does not recommend shaving off moles. Many patients who go to a dermatologist complaining of moles will end up having the moles shaved, because many dermatologists are not comfortable with performing excisions and fine suture closure. Many dermatologists deal with these moles by performing what is called a “deep shave.” This means that the lesion is essentially “scooped out,” with the shave extending lower than the surface of the skin. While this is more likely than a flat shave to remove the entire mole, the resulting scar is generally quite unfavorable, appearing as an indentation in the skin, much like a chicken pox scar. Dr. Rapaport does not perform deep shaves for the reasons noted above.
