With age, many people’s skin will become very poor, dark yellow, wrinkles and large pores. These problems need to be faced by many people, so many people will use photorejuvenation to solve this problem. Is the effect of photorejuvenation good?
Photorejuvenation is a kind of noninvasive photoelectric therapy. Its principle is to produce a continuous strong pulse substance – photon, which acts on skin tissue to produce photothermal and photochemical effects: the principle of selective photothermal action
Intense pulsed light can penetrate the skin and be preferentially absorbed by the pigment in the skin and heme in the blood. Without damaging the normal skin, it can coagulate the blood vessels, destroy and decompose the pigment groups, so as to achieve the effect of treating telangiectasia and pigment spots.

Intense pulsed light acts on the skin tissue to produce photothermal and photochemical effects, rearrange the collagen and elastic fibers of the skin, restore the elasticity of the skin, and help eliminate or reduce wrinkles and narrow pores.
The skin care principle of “photon rejuvenation” mainly uses the “selective photothermal effect of light” to improve the condition of skin. The tissue of human body has different ability to absorb light of different wavelengths. Pulsed light with a specific wavelength can penetrate the skin and be preferentially absorbed by melanin in the skin and hemoglobin in blood vessels.
After the pigment cells absorb the energy of light, they convert the light energy into heat energy. When the temperature rises to a certain extent, the pigment tissue will degenerate and the pigment tissue will necrosis, so as to achieve the purpose of removing color spots.
After the hemoglobin in the capillaries absorbs the light energy of a specific wavelength, the hemoglobin explodes, causing the dilated capillaries to rupture and the capillaries on the skin surface to close, which has the effect of improving the red blood filaments.
Intense pulsed light can cause photothermal effect and photochemical reaction in the skin. Stimulated by the thermal effect of pulsed light, fibroblasts can be transformed into fibroblasts, promote the secretion of collagen by fibroblasts, shorten the length of collagen, increase skin elasticity, reduce relaxation, remove small wrinkles and narrow pores.
