Epilation performed by laser was performed experimentally for about 20 years before it became commercially available in the mid 1990s. Intense Pulsed Light (IPL) epilators, though technically not a laser, use xenon flash lamps that emit full spectrum light. Hair color and skin type are the key factors that influence the success of laser hair removal. It’s most successful on people with dark hair (brown or black) and light skin.
Hair removal lasers have been in use since 1997 and the Food and Drug Administration approved it for permanent hair reduction. Laser hair removal has become extremely popular because of its speed and efficacy, although some of the efficacy is dependent upon the skill and experience of the laser operator, and the choice and availability of different laser technology at the clinic which is performing the procedure. Some will need touch-up treatments, especially on large areas, after the initial set of 3-8 treatments
Laser Hair removal can be performed on any area of the face or body and is faster and easier than other methods of hair removal. Laser hair removal is effective only on short, apparentable hair. Two to three days before the procedure, you shave the area to be treated, and allow it to grow to a stubble. Avoid waxing or plucking the hair and electrolysis three weeks before treatment. Laser hair removal is not for everyone. The absolute requirement is that one’s hair must be darker than the surrounding skin. Several wavelengths of laser energy have been used for hair removal, from visible light to near-infrared radiation. Hair removal lasers are effective treatment for pseudofolliculitis barbae. Treatment cost varies with the size of the area treated.
How does laser hair removal work?
During the procedure, your doctor 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 health care providers operate the laser, then laser light inserts into the surface of the skin to tiny sacs wherever hair development originates.
How long will the procedure take?
This varies depending on the area of the body. Treatments can take anything from 10 minutes to 1 hour.
Are the results permanent?
Results vary depending on skin and hair type. Studies have shown that many patients can achieve permanent hair loss of up to 85-90% and remaining hair returns lighter and softer.
