The theoretical basis of the photorejuvenation machine for the treatment of skin diseases is the principle of selective photothermal action. The fractional laser uses a wide spectrum, which can cover a variety of color bases, such as melanin, oxidized hemoglobin, etc.

When the fractional laser acts on the skin, the skin will generate a lot of heat by absorbing light, so that the subcutaneous temperature reaches 45-60 degrees, thereby promoting collagen regeneration, collagen regeneration, collagen fiber tightening, and also can promote blood circulation, Improve dull complexion, shrink pores and firm skin.

For hair removal and pigmented diseases, melanin selectively absorbs the spectrum of IPL to produce an implosion effect, or selective thermal decomposition, melanocytes can be destroyed, and melanosomes can be crushed.

For vascular diseases, the light energy of IPL is preferentially and selectively absorbed by oxyhemoglobin in the blood vessels, and converted into heat energy to heat up in the tissue. When the blood vessel heats up and damages the blood vessels, it can coagulate and destroy the blood vessels, so as to achieve the purpose of treatment.
