do you know about invisible foundation, cream and so on? Cosmetic, if you want to have it for a long time, you can use photon rejuvenation to whiten your skin. Do you know photon rejuvenation? Color light rejuvenation is a non-invasive skin medical technology. Its comprehensive efficacy can improve skin quality, solve skin problems, reduce fine lines, remove stains, shrink pores, whiten skin, and have firm and beautiful skin in one course. This technology rose in the United States and became popular all over the world, and became the royal skin care method for celebrities. The Italian intelligent skin rejuvenation instrument IPL is a beauty instrument that integrates skin care and treatment. What is the therapeutic principle of photon rejuvenation technology? A, biological stimulation: the photochemical action after intense pulsed light acts on the skin, which makes the chemical changes of molecular structure in collagen fibers and elastic fibers in the dermis, and restores the original elasticity. In addition, its photothermal effect can enhance the function of blood vessels and improve circulation, thus achieving the therapeutic effect of eliminating wrinkles and narrowing pores. B. Photothermal decomposition principle: Because the content of chromophore in diseased tissue is far more than that in normal skin tissue, the temperature rise after absorbing light is also higher than that of skin. Using their temperature difference, the diseased blood vessels are sealed and the pigments are broken and decomposed without damaging normal tissues. I don't understand it very well either. I copied it on this website of Xuzhou Xinyuan Plastic Surgery Hospital. Please have a look, anyway, there are advantages and disadvantages! Now that technology is so developed, you are afraid that you can't whiten it, hehe @
