With Alexandrite laser hair removal, pulses of light are directed at the melanin—i.e., the pigments in body hair—at varying depths. These pulses target the hair follicle, causing the hair to fall out and, in the medium to long term, reducing its growth or even inhibiting it completely.

Alexandrite laser hair removal is suitable for any part of the body. Therefore, it is appropriate for laser hair removal on the underarms, face, bikini line, arms, buttocks, and legs, among many other areas. Optimal results are seen in patients with dark skin and hair, who fall within Fitzpatrick skin types I to III, and occasionally up to type IV.
