Underarm laser hair removal is a cosmetic treatment that eliminates hair from the underarm area by emitting laser light energy deep into the skin to destroy the hair follicle. This method is effective only when the hair is in its growth stage.

How Underarm Laser Hair Removal Works

Underarm laser hair removal works by targeting the pigment in the hair follicles with concentrated beams of light. The melanin in the hair absorbs the light energy, which then converts to heat, damaging the follicle and inhibiting future hair growth. This process effectively removes unwanted hair while leaving the surrounding skin undamaged. Multiple sessions are typically required to achieve long-lasting results, as hair grows in different stages and the treatment is most effective during the active growth phase.
