The principle of LED PDT treatment

The wavelength of red light is 630nm-700nm, which has the functions of anti-inflammation, detumescence, pain relief and antipruritic. Red light has no strong thermal effect, and has stronger penetrating power than ultraviolet light. It can act on deeper tissues of 2-5cm. Due to the direct action of red light, it can reach deep into the submucosal layer of the skin, and the light energy is absorbed by tissue cells, which can increase cell activity, promote protein synthesis and energy metabolism, enhance the phagocytosis of white blood cells, accelerate blood circulation, increase skin elasticity, improve skin sallowness, and dullness. Dumbness and other conditions, so as to achieve anti-aging, anti-oxidation, and skin repair effects, also known as bioactive light. Whitening and rejuvenating skin, shrinking pores, anti-inflammatory and analgesic.

The wavelength of blue light is 430nm-450nm, which has the effect of rapidly inhibiting inflammation. Through the photodynamic effect, it stimulates porphyrin in skin enzymes and releases a large amount of singlet active oxygen, thereby destroying Propionibacterium acnes and reducing inflammation. It can effectively reduce the formation of acne, with quick effect, short course of treatment and few adverse reactions. Anti-acne and anti-inflammatory, improve bloodshot, control oil.

The wavelength of yellow light is 570-600nm, which has a good soothing and therapeutic effect on sensitive skin and skin in the allergic stage.

Remove freckles and desensitize, speed up healing and improve immunity.

The wavelength of orange light is 600-630nm, which is milder than red light and stronger than yellow light. It can promote blood circulation, enhance metabolism and thyroid function. Orange light has a good softening effect on arteriosclerosis, brain sclerosis and coronary arteriosclerosis, and can also promote appetite and treat emaciation and anemia. Cosmetic effect: prevent dry skin, enhance skin elasticity, stretch wrinkles, stretch marks, delay skin aging. Prevent dryness, increase elasticity, and speed up metabolism.

Application departments: dermatology, burns, rehabilitation physiotherapy, plastic surgery, obstetrics and gynecology, orthopedics, etc.

The wavelength of the mixed light is 400-700nm, and its main function is to accelerate tissue metabolism. The mixed light energy penetrates the deepest part of the skin and accelerates skin metabolism.
