The principle of color light rejuvenation and whitening is mainly to use selective light absorption, because different tissues will absorb light with different wavelengths, and intense pulsed light with a specific wavelength will penetrate the epidermis, be selectively absorbed by chromophore and hemoglobin and be converted into heat energy, thus stimulating the rearrangement of collagen fibers and elastic fibers in the deep skin, restoring the elasticity of the skin, improving the metabolic environment of the skin, and then having the effect of rejuvenation and whitening.

The above was introduced by experts from Qingdao Huahan Plastic Surgery Hospital.
