RisksBy Mayo Clinic staff
Laser hair removal doesn't guarantee permanent hair removal. Some hair could be resistant to the laser treatment or grow again after treatment — although the new hair growth might be finer and lighter in color.
The most common side effects of laser hair removal include:
- Skin irritation. Temporary discomfort, redness and swelling are possible after laser hair removal. Any signs and symptoms typically disappear within several hours.
- Pigment changes. Laser hair removal might darken or lighten the affected skin, usually temporarily. Skin lightening primarily affects those who have darker skin, especially if an incorrect laser is used at an incorrect setting.
Rarely, laser hair removal can cause blistering, crusting, scarring or other changes in skin texture.
Laser hair removal isn't recommended for the eyelid or surrounding area, due to the possibility of severe eye injury.
