Deliver precise 1927nm laser energy to the skin’s surface and superficial dermis, creating controlled micro-peeling while stimulating collagen regeneration for improved tone, texture, and clarity.1927nm laser has a high absorption rate for water. Since the water content in the human body is 50%-70%,1927nm can be well absorbed by the human body, thereby achieving micro-peeling and thermal effects on the surface of the skin and the superficial dermis, thereby promoting skin renewal and collagen regeneration
