Laser hair removal is the process in which unwanted body or facial hair is removed using direct beams of targeted light. Because they are so precise, lasers can target dark areas of the skin to remove hair without damaging the surrounding tissue. Lasers have been used in hair removal and permanent hair reduction for more than a decade, and the process has become popular with millions of patients due to its speed and efficiency.
Laser Hair Removal Treatment
Laser hiar removal works by targeting melanin, or dark matter, in the skin. Melanin is what gives hair and skin their color. Because of their high temperature and precision, lasers are able to target this matter and cause localized damage to the hair follicle that removes the hair and helps to prevent future growth. While intended to slow hair growth, laser hair removal does not guarantee permanent results. In most cases, patients need to undergo several treatments and occasional maintenance treatments in order to remain hair-free.
During a laser hair removal treatment, patients are given special goggles to protect their eyes from the laser. The procedure is performed on an outpatient basis, most often in a doctor’s office or cosmetic surgery center. Topical anesthetic may be applied to the skin to reduce pain or discomfort. The doctor will treat the desired area or areas using a hand-held laser device. When in use, the device creates a laser beam that passes through the skin to target hair follicles. Many patients experience a burning or stinging sensation, but it usually is not severe, Sessions can take anywhere from a few minutes to several hours depending on the size of the area being treated. For best results, many patients need multiple sessions.
Recovery From a Laser Hair Removal Treatment
Immediately following the procedure, the skin may be red and swollen. Patients also may feel a stinging sensation for the first few days. During the healing process, the skin should be kept clean using soap and water. It should be not scrubbed vigorously, and any scabs that form should not be picked. Avoiding sunlight is also important while the skin heals.
Results vary from person to person, but most patients experience hair loss and delayed regrowth after the first treatment. Extended period of delayed hair regrowth typically only occurs following multiple treatments. The potential side effects of laser hair removal are limited and include temporary skin irritation, pigment changes, scars, blisters, or changes in skin texture.
