Although touted by infomercials as “pain free,” electrolysis can produce anywhere from mild irritation to sharp pain since pain-sensitive nerve endings are right next to hair follicles. Furthermore, since electrolysis only destroys one follicle at a time, it can be a slow process. Electrolysizing an upper lip, for instance, can take anywhere from four to ten hours. For many, the discomfort and wait are well worth the removal of unsightly hairs. But in the wrong hands an electrolysis needle can permanently damage skin around the follicles. So, despite the abundance of home products, it’s best to visit a professional electrologist.
