Problems With Laser Hair Removal

Laser hair removal consists of beaming a laser into the skin to kill the hair follicle. This slows or eliminates hair growth. The dark pigment in the hair absorbs the laser beam, which is why the procedure works best on black or brown hair. Laser hair removal is typically used on legs, underarms, bikini areas, facial hair and backs, although it can be used wherever hair is not wanted. Always use a certified medical professional; getting the procedure done by an unqualified technician increases the risk of tissue burns, lesions and scarring.

Hair and Skin Color

Because the laser beam targets dark pigment in the skin, laser hair removal is significantly less effective on light hair colors, such as blonde, red, light brown, gray or white. The ideal combination for this type of removal is dark hair and light skin so that the beam can target the hair without harming the skin. Although technological developments have been made, the feasibility of using the laser on dark skin is still uncertain, since dark skin is at risk of absorbing too much of the laser energy.

Regrowth

Laser hair removal cannot guarantee permanent hair loss. Percentages and rates of hair regrowth have not been established, but the amount of regrowth will vary depending on the person. It is possible that certain sections of your hair won't be affected by the treatment, or may grow back faster than you would like.

Hyperpigmentation

In some cases, especially in patients with darker skin tones, the laser treatment may result in increased melanin production, known as hyperpigmentation. This means that the treated skin will darken, as though you're getting a tan. The darkening is usually temporary, however, and can be reversed.

Hypopigmentation

Dark-skinned patients are also at an increased risk for hypopigmentation, or lightened skin. Sometimes, the laser energy will stop or slow melanin production in the skin. Unlike hyperpigmentation, lightened skin is not reversible.

Discomfort

As the laser hits the hair follicle, you may experience a stinging sensation, like a rubber band being snapped against your skin. Taking an over-the-counter pain medication before the procedure can help, and if you're really sensitive to pain, your doctor can use a topical local anesthetic to numb the treated area.

After-effects

There are several potential after-effects to laser hair removal, including redness, swelling, blistering and crusting. These effects are usually temporary, but can be uncomfortable. Treat your sensitive skin very carefully: keep it cool for the first 24 hours and avoid scrubbing for several weeks following the treatment.

Expense

The average cost for one session of laser hair removal is in the hundreds of dollars, according to the American Society of Plastic Surgeons. Keep in mind that you may need more than one session, depending on the amount of hair you have and the results you want. Most insurance companies will not cover laser hair removal, so the procedure may end up being too costly for some people.
