Treatment Principle：

The system utilizes an optimal 808nm diode laser wavelength to penetrate deeply into the dermis where the hair follicles reside. During treatment, a series of low-fluence, high-repetition pulses gradually raises the temperature of both the hair follicle and its surrounding nourishing tissue to 45°C. This gradual heat delivery effectively uses the chromophores in the surrounding tissue as reservoirs to pre-heat the hair follicle. Combined with the thermal energy absorbed directly by the follicle itself, this process damages the follicle structure and prevents hair regrowth.

The 808nm diode laser is highly selective, targeting melanin within the hair shaft and follicles without injuring the surrounding tissue. As the melanin absorbs the laser light, it converts the energy into heat, rapidly increasing the follicle's internal temperature. Once the temperature rises high enough to cause irreversible structural damage, the follicle naturally degenerates through physiological processes, achieving permanent hair reduction.
