In recent years, because acne often appears in different parts of a person, the treatment of acne has attracted much attention. Whether it is in advertisements or in newspapers, the treatment of acne often appears in front of people. Speaking of treatment methods, the most popular is red light to treat acne, but why can red light treat acne? I will explain it to you today.
Red light treatment is to filter most of the red light, mainly in the red light band, and its biological effect is mainly photochemical. Rather than heat.
The penetration depth of red light can reach 10-15mm, and it directly affects the subcutaneous tissue. Mitochondria in cells absorb the most red light. After red light is irradiated, the catalase activity of mitochondria increases, which can increase cell metabolism; increase the glycogen content, increase protein synthesis and increase the decomposition of adenosine triphosphate, thereby strengthening the cell`s Regenerate, promote the healing of wounds and ulcers; at the same time, it also increases the phagocytosis of white blood cells and improves the body's immune function. Red light treatment can promote the healing of wounds and ulcers, promote hair growth, promote fracture healing, and accelerate the regeneration of damaged nerves.
Light is effective for acute, subacute and chronic acne inflammation. Because it can increase the phagocytosis of white blood cells, it also improves the body's immune function, which increases the body's defense function, which can promote acne healing and reduce recurrence. In addition, in the early and middle stages of acne inflammation, the content of serotonin in local tissues increases. This serotonin can cause pain in the body. After being irradiated with red light, the content of serotonin can be reduced, thus playing an analgesic effect.
Red light has no obvious adverse effects on human skin. The specific mechanism of action is not yet clear, and the treatment methods are not uniform. Therefore, the treatment of acne by red light needs to be further explored.
