Skin Rejuvenation

What is "Photorejuvenation" "Photorejuvenation is the use of light energy to rejuvenate and whiten the skin. The biggest difference between "photorejuvenation" and "fractional laser" is that the "light" used is different.

 

Working Principle 

"Photorejuvenation works mainly by using the selective photothermal action of light to improve the condition of the skin. The body's tissues have different absorption capacities for different wavelengths of light. Specific wavelengths of pulsed light penetrate the skin and are preferentially absorbed by melanin in the skin and hemoglobin in the blood vessels.

 

After the pigment cells absorb the energy of light, the light energy is converted into heat energy, and the temperature rises to a certain degree, the tissue of pigment produces denaturation and the pigment tissue necrosis to achieve the purpose of removing pigmentation.

 

After the hemoglobin in capillaries absorbs the light energy of specific wavelength, the hemoglobin explodes, triggering the rupture of dilated capillaries and the closure of capillaries on the surface of the skin, which has the effect of improving redness.

 

Intense pulsed light can trigger photothermal effects and photochemical reactions within the skin. Fibroblasts stimulated by the thermal effect of pulsed light can be transformed into fibroblasts, promoting fibroblasts to secrete collagen, shortening the length of collagen, increasing skin elasticity, reducing sagging, removing fine wrinkles and reducing pores.
