Unwanted facial and body hair is a common problem that can be a source of distress for men.
Many treatment options for managing unwanted hair have been available over the years, such as shaving and waxing, but these methods are temporary and offer varying degrees of success.
Laser devices send specific concentrated beams of light through the skin that are absorbed by the melanin (dark) pigment present in the hair follicle shafts. The light gets converted to heat and affects the hair growing stem cells, which in turn reduces the hair growth Because hair grows in cycles, repeated treatments are necessary to destroy the hair follicles.
Treatments should be performed by or under the direct supervision of a dermatologist or other physician who has appropriate training and expertise. Darker hair responds best to laser hair removal.
The most common side effects include discomfort, swelling, and redness that last one to three days.
The percentage of hairs removed per session varies by location on the body, with thinner-skinned areas (e.g., armpits and bikini area) generally responding better than thick-skinned areas (e.g., back and chin).
About 10 percent to 25 percent reduction in hair growth can be expected with each treatment. Treatments are repeated every four to eight weeks. The hair that regrows following treatment tends to be lighter and finer in texture. Patients are instructed to avoid sun exposure and to use a broad-spectrum sunscreen with a Sun Protection Factor (SPF) of 30 or higher following the procedure.
