Laser hair removal targets the entire hair structure, from the hair shaft, down to the follicle,meeting the principle of selective photothermolysis. Light energy with a specific wavelength is primarily absorbed by the endogenous chromophore melanin resulting in rapid heating which is required for local thermal necrosis of the follicles’regenerative structures.
To achieve permanent hair removal, the laser system must be able to effectively treat the different hair types and colors as well as the various skin types while providing maximum skin protection. The laser's wavelength, pulse duration and spot size determine the effectiveness of the treatment (on all skin types) and also influence the depth of penetration and treatment speed.
