Red and blue light therapy instrument uses high-purity, high-power density red, blue and yellow light to irradiate the skin, which can change the cell structure, kill bacteria, provide a suitable environment for new cells, enhance the production of new collagen elastin and collagen, and promote cell growth; it can repair inflammatory acne aging skin, relieve sunburned skin without harming the skin, whiten the skin, and promote skin elasticity. The red and blue light therapy instrument uses a narrow-spectrum light source to emit a cold light that does not produce high heat and does not burn the skin. It converts light energy into intracellular energy and is one of the safest and most effective instruments for acne treatment and skin rejuvenation. Clinical applications: 1. Red light: red light with a wavelength of 635 nm has the characteristics of high purity, strong light source and uniform energy density, which is effective in skin care and health care treatment, and is called biologically active light. Red light can increase cellular activity, promote cellular metabolism, and cause the skin to secrete collagen and fiber tissue to fill itself. It accelerates blood circulation, increases skin elasticity, improves skin yellowing and dullness, thus achieving anti-aging, anti-oxidation and repair effects that cannot be achieved by traditional skin care. The main effects: whitening and light spots, repairing damaged skin, smoothing fine wrinkles, reducing pores, and increasing collagen protein. 2. Blue light: Blue light with a wavelength of 415nm has the effect of quickly suppressing inflammation. In the process of acne formation, it is mainly Propionibacterium that is at work, and blue light can efficiently destroy this bacteria without damaging the skin tissue, minimizing the formation of acne, and significantly reducing acne in the inflammatory stage to healing within a short period of time. Treatment advantages: 1. Non-contact, non-invasive treatment, fast results, short course of treatment, small and mild side effects; 2. 6, light source irradiation output stable treatment dose stable each treatment are 20 minutes each, 2 times a week, 8-10 times a course of treatment.
