Laser hair removal is a process that uses a concentrated beam of light from a special laser hair removal device to remove the dark unwanted hair.
There are various devices that aid in the process of unwanted hair removal. During laser hair removal, a laser emits a light that is absorbed by the pigment (melanin) in the hair. The hair pigment has to be dark for the laser to be effective. The light energy is converted to heat, which damages the tube-shaped sacs within the skin (hair follicles) that produce hairs. This damage inhibits or delays future hair growth.
Laser hair removal effectively delays hair growth and resets thick dark hair to finer lighter hair, but it does not always result in permanent hair removal. In order to reduce hair multiple laser hair removal treatments are needed for initial hair removal, and maintenance treatments might be needed as well. Laser hair removal is most effective for people who have light skin and dark hair.
Risks of Laser Hair Removal
A few common risks of laser hair removal depends on skin type, hair color, and treatment plan. The treatment plan includes pre-treatment and post-treatment care.
Two major laser hair removal risks:
- 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 don't avoid sun exposure before or after treatment and those who have darker skin.
