Laser hair removal is a procedure used to remove unwanted hair. It is faster and less painful than other methods of hair removal, as well as longer lasting and more permanent.

The procedure uses laser light energy, which passes through the skin to destroy hair follicles. Hair in the treated area may be permanently reduced and hair that does grow back tends to be slow-growing, as well as thinner and lighter. Multiple treatments are typically necessary, and people with light skin and dark hair tend to have the best results. Any area of hair can be treated, with the exception of the area around the eyes.

Laser hair removal is typically performed by a technician, who is supervised by a dermatologist. The patient’s skin type and hair are evaluated and a spot test is usually done to assess response. If the patient has a tan, the treatment must be postponed until the tan completely fades.

During the procedure, the patient may feel mild discomfort or pain. The treatment may take a few minutes to several hours, depending on the size of the area treated.

Redness and swelling will occur in the area following treatment and usually goes away in several days. The patient can return to normal activities immediately, but avoiding direct sun exposure is generally recommended for at least a week.

Adverse effects are rare if the procedure is performed properly by an experienced laser technician. The most common side effect is lightening or darkening of the skin. Other possible reactions include burning, blistering and scarring.
