Consumer Advice: Laser Hair Removal
Dermatologists have been using lasers to remove dark spots, tattoos, acne scars, and other blemishes for over a decade. Laser hair removal to remove unwanted hair has increased in popularity in recent years. This procedure works by the laser passing through the skin to an individual hair follicle. The heat of the laser damages the hair follicle and inhibits future growth. The Mayo Clinic says that hair color and skin type will influence the success of laser hair removal and is most effective for people who have light skin and dark hair because the laser targets the pigment in the hair.
If you are interested in laser hair removal, it is recommended that you schedule a consultation with a doctor who is board certified in dermatology or cosmetic surgery and has experience with laser hair removal. To prepare for the procedure, stay out of the sun. A tan may increase the risk of side effects. Also, avoid plucking, waxing, and electrolysis as this may disturb the hair follicle and interfere with the removal. However, shaving is okay because it preserves the hair shaft and follicle. After the procedure, you may notice redness, swelling, and experience a stinging sensation. While you are healing, wash your skin gently with soap and water and avoid sun exposure for at least a week. The most common side effects of laser hair removal include skin irritation and pigment changes. In rare cases, laser hair removal may cause blistering or scaring.
Laser hair removal does not guarantee permanent hair removal. Results vary from person to person. Some hair may be resistant to the treatment or hair re-growth is still possible. Multiple treatments may be necessary to achieve your desired results. For more information contact the FDA Consumer Health Information.
