808nm is considered the ideal wavelength for hair removal because it effectively targets melanin (pigment) in hair follicles while minimizing damage to surrounding tissue. In the case of hair removal, the 808nm diode laser emits light of a specific wavelength to target and heat the melanin in the hair follicle, ultimately destroying its growth.

The 808nm diode laser hair removal machine is popular in the beauty and dermatology industries due to its effectiveness, relatively little discomfort compared to other hair removal methods, and ability to treat a variety of skin and hair types.
