Alexandrite laser hair removal machine is a type of laser hair removal device that uses an alexandrite crystal to produce a specific wavelength of light. This wavelength is absorbed by the melanin in the hair follicle, which damages the follicle and inhibits future hair growth. Alexandrite laser hair removal machines are considered effective for removing unwanted hair on various parts of the body, including the legs, arms, underarms, bikini area, and face. They are also known for their speed, accuracy, and relatively low level of discomfort compared to other types of laser hair removal devices.
