The laser of a hair removal device emits a certain amount of radiation, but this radiation typically falls within a safe range and does not pose significant health risks to users. Laser hair removal works on the principle of selective photothermolysis, whereby the melanin in hair follicles absorbs heat and becomes damaged, thereby destroying the follicular structure to achieve permanent hair removal.
During this process, the laser hair removal device emits light beams that are primarily absorbed by the hair shafts and follicles. The generated thermal energy is also mainly absorbed and dissipated by these tissues, resulting in relatively low radiation exposure. However, during use, one should follow the manufacturer's operational instructions and avoid directly shining the laser into the eyes to prevent ocular injury.
It is recommended to choose reputable brands and purchase hair removal devices through authorized channels to ensure product safety and effectiveness. During use, protective eyewear should be worn to prevent eye irritation from the light. After hair removal, proper skincare should be performed, spicy and irritating foods should be avoided, and the skin should be kept clean and dry.
