Doctor: LED light can improve the skin

The Second Affiliated Hospital of Lanzhou University, Department of Dermatology, chief physician, M.D., associate professor Wei Yuping said, LED illumination device which belongs to the scope of photodynamic therapy in clinic, it can improve the skin, but must be used properly.

The Second Affiliated Hospital of Lanzhou University, Department of Dermatology, chief physician, associate professor of medicine, Dr. Wei Yuping in an interview with reporters cctv.com, LED illumination device which belongs to the scope of photodynamic therapy in clinic, it can improve the skin, but must be used properly.

Wei Yuping explained, LED light is used to treat the role of light, rather than heat. The skin is usually composed of epidermis, dermis and subcutaneous tissue, the red blue light can stimulate the metabolism of mitochondria in each cell, which has a certain role. If the red light wavelength of 635 nm, in the medical clinic, red light can promote wound healing and increase the phagocytosis of white blood cells; in beauty, can stimulate and promote cell proliferation effect of collagen, The new supersedes the old., can tighten the pores in the skin, and skin inflammation can also be red light. Blue, 415 nm wavelength, in the medical clinic, blue light has bactericidal effect, they are typically used to treat acne; in beauty, is has a calming effect on the skin proper, emotional stability, attention etc.. But Wei Yuping believes that the business is still the effect of claims exaggerated.

In fact, there will be red and blue light equipment, large general hospital Wei Yuping said: "ordinary people can also choose to purchase equipment to improve the skin, but it must be noted that the choice of products must be through the national certification. Because some products, especially small manufacturers of equipment, red and blue wavelengths are not up to the relevant provisions, the role is not great. In addition, the use of red and blue light frequency can not be too high, not more than two times a week. "

Thus, LED light can improve the skin, is true. Although the cold light source is a natural treatment to promote skin regeneration, but experts also remind the public, the use of LED light meter frequency can not be too high, up to two times a week. At the same time, the improvement of the skin is related to many factors, such as sleep, mood, physical condition, and so on.
