Laser - Laser Hair Removal
Laser hair removal is a popular cosmetic procedure that uses targeted laser energy to safely and effectively remove unwanted hair without damaging the surrounding skin. Common treatment areas include the chin, upper lip, chest, underarms, back, bikini line, and legs.
While temporary hair removal methods like tweezing, shaving, depilatory creams, and waxing are available, many people prefer the more permanent and less irritating/painful option of laser hair removal. This safe and generally comfortable procedure can remove hair from almost any area of the body (with the notable exception of the eye area, due to the risk of serious eye injury).
Candidates for Laser Hair Removal
Laser hair removal works by targeting the melanin (pigment) in hair follicles. Historically, the most effective results were achieved on individuals with light skin and dark hair. Those with blond, red, gray, or white hair, as well as those with dark skin, were often less suitable candidates. However, advancements in laser technology have improved the effectiveness of laser hair removal for individuals with darker skin tones. Research is also ongoing to develop effective methods for removing lighter-colored hair.
Benefits of Laser Hair Removal
Laser hair removal offers numerous advantages for those looking to eliminate unwanted hair:
Precision: The laser precisely targets hair follicles, leaving surrounding skin untouched.
Speed: The procedure is relatively quick.
Long-lasting Results: For the majority of patients (around 90%), results are permanent or very long-lasting.
Comfort: While some patients may experience mild discomfort (often described as similar to a rubber band snap against the skin), many find laser hair removal to be virtually painless.
Laser Hair Removal Procedure
During laser hair removal, a topical anesthetic is often applied to numb the treatment area. A handheld device emitting intense laser pulses is then passed over the target region, focusing on individual hair follicles. Various laser hair removal methods exist, some incorporating radiofrequency energy in addition to laser pulses. The most suitable treatment approach for each patient is determined in consultation with their physician.
Hair growth occurs in three cyclical phases. Laser hair removal is most effective during the anagen (active growth) phase, as hair follicles are most receptive to laser energy at this stage. However, since not all hairs are in the same growth phase simultaneously, multiple laser treatments are required. Typically, patients need between three and five sessions, spaced 4 to 8 weeks apart. The precise number of treatments can vary depending on hair texture and the treatment area.
Recovery from Laser Hair Removal
Following laser hair removal, some redness, soreness, or swelling may be experienced. These effects are typically temporary and subside within a few days. Discomfort can be minimized with cold compresses, ice packs, moisturizers, and anti-inflammatory creams. It's crucial to avoid sun exposure for a period of time after treatment.
Complications of Laser Hair Removal
While laser hair removal is generally safe and effective, some potential complications can occur. The most common is regrowth of some hair, though this regrowth is often finer and lighter than the original hair. Additional treatment sessions can usually address this. Other possible side effects include skin irritation (such as blistering and crusting), changes in skin pigmentation or texture, and, in rare cases, scarring at the treatment site.
