I am 24 years old this year. Every time summer approaches, I need to take care of my underarms, but the depilatory cream never removes all the hair. I would like to know if laser hair removal is available for underarms.

In general, the underarms can be treated with laser hair removal, a physical treatment method that uses light energy to penetrate deep into the skin and destroy hair follicles, thereby achieving hair removal. This method not only provides noticeable results, but also has minimal side effects and a low probability of recurrence after treatment. Laser hair removal can be applied to multiple body areas, including the underarms, legs, arms, and chin. For underarm hair removal, the laser can reach deeply into the hair follicles, inhibit hair growth, and thus achieve permanent hair removal.

Underarm hair growth cycles are divided into the anagen (growth) phase, catagen (regression) phase, and telogen (resting) phase. Laser treatment is only effective on hair follicles in the anagen phase; therefore, multiple treatments are necessary to cover all hair growth cycles and achieve optimal results. Treatment plans should be adjusted according to individual hair density, color, and skin response to ensure effectiveness.

However, it is important to keep the underarms clean before treatment, avoiding residual oils and sweat. Laser hair removal should be avoided during menstruation, pregnancy, or lactation. To ensure safety and effectiveness, treatment should be performed at a reputable facility, and pre-treatment preparation and post-treatment care should follow the physician's instructions.
