The 808nm wavelength laser can accurately locate the hair follicle, and its penetration depth can match the position of the hair follicle, and can be efficiently absorbed by the melanin in the hair follicle, directly destroying the hair follicle stem cells and blocking the hair regeneration path. 808nm freezing point hair removal technology During the hair removal process, the device will simultaneously release cooling substances to keep the skin feeling cold, greatly reducing the burning and pain during hair removal, and making the entire hair removal process more comfortable. The 808nm wavelength is highly adaptable to different skin types and hair colors. Whether you have light or dark skin, as well as coarse or fine hair, you can achieve safe and effective hair removal by adjusting the appropriate energy density. This wavelength avoids the absorption peaks of hemoglobin and water in the skin, reducing energy waste and damage to the skin. It effectively reduces the risk of thermal damage to the skin and reduces the occurrence of adverse reactions such as redness and swelling of the skin after hair removal. It has CE/ROHS safety certification and provides 1 year free warranty service for non-human damage. Support language customization..syi
