Risks

Risks of side effects vary with skin type, hair color, treatment plan and adherence to pre-treatment and post-treatment care. 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. These changes might be temporary or permanent. Skin lightening primarily affects those who don't avoid sun exposure before or after treatment and those who have darker skin.

Rarely, laser hair removal can cause blistering, crusting, scarring or other changes in skin texture. Other rare side effects include graying of treated hair or excessive hair growth around treated areas, particularly on darker skin.

Laser hair removal isn't recommended for eyelids, eyebrows or surrounding areas, due to the possibility of severe eye injury.
