Picture showing the laser hair removal procedure Laser hair removal procedure

A doctor or trained nurse presses a hand-held laser instrument to your skin. Depending on the type of laser, a cooling device on the tip or a cool gel is used to protect the skin.

When the doctor activates the laser, the laser light passes through your skin's surface to tiny sacs (hair follicles) where hair growth originates. The intense heat damages the hair follicle, which inhibits hair growth. It takes several treatments to provide an extended hair-free period.

During the procedure
You wear goggles to prevent accidental exposure of your eyes to laser light. When the laser is activated, you feel a stinging sensation. Oftentimes a topical local anesthetic is applied before the procedure to reduce discomfort. The procedure causes a slight charring of stubble. You may notice a strong odor of singed hair, which is normal.

How long the procedure takes depends on the area of the body involved. A small area such as the upper lip may take several minutes. A larger area such as the back may require several hours.

After the procedure
After laser hair removal, no medications or bandages are necessary. You may notice some redness and swelling for the first few hours. Also, stinging may occur for the first 24 to 48 hours. Some people experience a slight crusting of the skin. If crusting occurs, keep the area moist with petroleum jelly (Vaseline).

After treatment:

  • Avoid exercise and exertion for the first 24 hours. Perspiration from exertion may increase irritation caused by the laser.
  • Avoid exposure to the sun for several weeks after treatment. After this period, make certain you apply sunscreen whenever you're in the sun. Avoid tanning booths — the ultraviolet light damages the skin.
  • Don't wax or pluck hairs for three weeks before treatments.
  • Don't pick at or manipulate the skin in treated areas.
  • Don't rub or scrub the treated area. You may gently wash the area with soap and water.
