1, red-yellow light is with the function of repairing the skin barrier, which is a common physical method for the treatment of sensitive dermatitis. It is characterized by safety, therapeutic effectiveness as well as widespread clinical use. The mechanism of red light and yellow light to repair the skin barrier is different.
2. Red light can penetrate into the deeper layers of the skin and produce photochemistry in order to induce macrophages to release a large number of cytokines, affect the calcium ion permeability of the cell membrane, enhance the phagocytosis of leukocytes, and eliminate inflammation. At the same time it can also stimulate cell growth factor secretion and cell proliferation, accelerate the speed of cell repair, but also inhibit the peripheral nerve pathological impulses, in order to achieve the role of anti-itching, anti-inflammatory and repair of the skin barrier.
3. Yellow light can directly act on the cell membrane of skin cells, cell nuclear membrane and mitochondrial membrane, causing a series of photobiostimulation response to promote the repair of tissues and skin barrier. When yellow light is absorbed by the skin, it can treat capillary dilatation, inhibit vascular nerve hyperreactivity, enhance the skin's tolerance and resistance, reduce skin sensitivity, and is suitable for sensitive skin.
4. After the treatment of red light and yellow light, excessive sun exposure should be avoided, as well as using less cosmetic products, strengthening moisturizing, and avoiding excessive cleansing, in order to maintain the barrier function of the skin.
