The pulse time of Ipl hair removal by semiconductor pulse light is from 5 seconds to 100 milliseconds, which can obtain ideal hair removal effect and effectively protect the epidermis from thermal damage.
Zhengzhou Huashan Plastic Surgery Hospital is very good. The 3D ipl hair removal in Zhengzhou Huashan Plastic Surgery Hospital uses the principle of light selectivity to directly destroy hair follicles. By adjusting the wavelength, pulse time and energy density of light, the operation can achieve the effect of selective photolysis. The instrument uses melanin in hair and hair balls to absorb light energy and convert it into heat energy, which is transmitted to hair follicles. When heated to 70℃ over 1ms, hair follicles will be destroyed, eliminating the environment where hair can regrow, thus achieving the purpose of one-time hair removal. However, because hair and hair balls need to absorb light energy and conduct heat to hair follicles, they can only treat growing hair, so ipl hair removal takes several courses.
