The action principle of photon is to destroy pigment, contract blood vessels, diminish inflammation and sterilize, control oil and balance oil, and increase the thickness of epidermis, which is beneficial to the thickness of dermis. In the plastic surgery industry, these are used to remove spots and treat blood vessels. Photons can also improve wrinkles on the skin, fade fine lines and improve some deep wrinkles. Photon has a therapeutic effect on red blood silk, which can stimulate the skin well, make the skin more and more elastic, and make the skin smoother and better looking. At the same time, it can improve the condition of large pores and make the skin more and more delicate. The above is an introduction to the principle of photon action. When photochemistry is used in the skin, the skin tissue will change and the tissue arrangement will be dense, which can promote the synthesis of collagen and improve the blood circulation of the skin, thus enhancing the skin resistance.
