Description More Choices for Treatment on Different Body Parts. 4 Different Spot Sizes Treatment Heads Changeable on One Handle •Gold Standard Working Energy - 10J+5ms. •Super Short,Pulse Duration •Super Long Life Span •Super High Power Treatment Principle This means that the 1800W 808nm Diode Laser works by emitting energy in the form of a laser beam, which is absorbed by the melanin present in the hair follicle and surrounding tissue. As a result, the temperature of the targeted area rises rapidly, causing thermal damage to the hair follicle and its shaft. Due to this damage, the hair loses its connection with its primary environment and effectively disappears from the area, resulting in long-lasting hair removal. Application: In conclusion, this hair removal device offers numerous benefits and features to ensure a safe, comfortable and effective hair removal experience for patients. Some of these benefits include: 1. Multiple Spot Sizes - With four different interchangeable treatment tips, the device offers versatility to treat different body parts and different hair types.
