The depilator is based on the principle of selective photothermal decomposition. When light strikes tissue, the pigment in the hair follicle selectively absorbs most of the light, leaving the surrounding tissue unheated. The melanin in the hair follicles absorbs light waves and produces heat, which ultimately stops hair follicle growth. As a result, hair follicles with more melanin (i.e., darker hair follicles) are better at absorbing light waves and shedding hair. DPL function skin beautifying technology uses intense pulse light to irradiate the skin. Intense pulse light can change and rearrange the internal structure of collagen fiber and elastic fiber of dermis, so as to restore the original elasticity of the skin. The photothermal effect produced by photon can penetrate deep skin, selectively act on subcutaneous pigment or blood vessels, decompose color spots, close abnormal red blood silk, solve all kinds of defects on skin! Therefore, it achieves the effect of whitening and tender skin!
