Recently, the Department of Dermatology of Zibo City Hospital of Traditional Chinese Medicine introduced a high-energy red and blue light photonic therapy instrument, which provides better treatment for acne, herpes zoster, baldness, skin ulcers, skin infections, eczema and other skin diseases. Red and blue light therapy instrument adopts advanced technologies such as high power semiconductor light source, multi-chip integration, and high power solid state light source output to produce specific wavelengths of high light power red light and blue light to act on the human body, effectively penetrating photon energy into the subcutaneous 3-5cm, blue light acts on target cells, producing significant effect of killing Propionibacterium acnes; red light is absorbed by cell mitochondria, promoting rapid cell metabolism, granulation tissue After red light is absorbed by cell mitochondria, it promotes rapid cell metabolism and granulation tissue growth, producing significant therapeutic effects. The mechanism of action of red and blue light therapy instrument clinical applications: 1. Blue light (wavelength of 415nm) has the effect of killing Propionibacterium acnes and promoting the recovery of inflammation. Propionibacterium acnes infection is one of the important reasons for the occurrence of acne. After high power blue light irradiation, photon energy is absorbed in large quantities by Propionibacterium acnes, activating the endogenous generation of bacterial photosensitizer porphyrins, which are converted into toxic monomorphic oxygen through photochemical reactions and rapidly kill Propionibacterium acnes. Combined with high-energy narrow-spectrum red light irradiation treatment, it can reduce the production of inflammation, significantly promote the recovery of inflammation, while reducing the erythema reaction associated with acne damage, reducing the formation of acne scars, and can significantly promote the production of skin collagen to restore smoothness to the skin of acne damaged areas. Blue light also effectively inhibits sebaceous gland oil secretion, has the ability to improve immune mechanisms, and prevents the recurrence of acne. The combination of blue light and red light is a new treatment method for acne, which has been widely used and is one of the recommended treatments in the latest edition of the textbook “Dermatologic Venereology” and the “Chinese Acne Treatment Guidelines”. 2. When red light (wavelength of 635nm) is irradiated for treatment, it produces an efficient enzymatic reaction to accelerate wound healing. Photon energy is absorbed by a large number of cell mitochondria, producing a series of photochemical reactions that promote the utilization of ATP and protein synthesis, thus promoting cell metabolism, improving tissue cell respiration, improving microcirculation and local nutrition, and accelerating granulation tissue growth and wound healing. Red light can make the cell activity increase, promote cell metabolism, and make the skin secrete collagen and fibrous tissue in large quantities to fill itself. It accelerates blood circulation and increases skin elasticity. It is mainly used for the treatment of skin infections, skin ulcers, folliculitis, boils, dermatitis, baldness and other skin diseases. 3.Red light irradiation has anti-inflammatory and analgesic effects. Red light treatment can increase the phagocytosis of white blood cells, improve the immunity of the body, and promote self-inflammation. Photonic biological effect can reduce the content of pentraxin (5-HT) in the inflammation site, producing significant analgesic effect. It is mainly used for herpes zoster and post-herpetic neuralgia, etc. Red and blue light therapy instrument features: 1, non-contact, non-invasive treatment, fast results, short course of treatment, no side effects; 2, the treatment of the entire face can be completed at once; 3, the light source output intensity is stable, the treatment dose is accurate; 4, can effectively enhance the activity of skin collagen cells, smoothing fine wrinkles; 5, acne twice a week for a total of 4-8 weeks, shingles and other skin diseases once a day for a total of 7-10.
