Laser Hair Removal

About laser hair removal

Lasers remove hair through a process of selective photothermolysis in which energy in the form of optical wavelengths is delivered into the hair shaft and pigmented follicular epithelium. The light is primarily absorbed by the endogenous chromophore melanin and results in a rapid rise in temperature and subsequent heat transfer to adjacent tissue, causing 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.
