1.All the laser hair removal system are with the same principal with a process of selective photothermolysis in which energy in the form of optical wavelengths is delivered into the hair shaft and pigmented follicular epithelium.
2. Then the light is primarily absorbed by the endogenous chromospheres melanin and results in a repaid rise in temperature and subsequent heat transfer to adjacent tissue, causing local thermal necrosis of follicles' regenerative structures.
3. To achieve Permanent Hair Removal, the Laser Hair Removal Machine must be able to effectively treat the different hair type 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 treatment and also influence the depth of penetration and treatment speed.
