1. Red light can penetrate the surface layer of the skin (about 1-3 millimeters), and after being absorbed by mitochondria, it enhances cellular energy (ATP) synthesis, helping damaged tissues to repair faster. For example, the recovery speed of muscle micro injuries after exercise can be improved by exposure to red light.
2. Red light can alleviate local inflammatory reactions by inhibiting the release of pro-inflammatory factors such as TNF - α and IL-6, while stimulating blood circulation and relieving chronic pain in joints and muscles. It has an adjuvant therapeutic effect on arthritis, tendinitis, and other conditions.
3. Red light can promote collagen production, shorten the wound healing cycle, and reduce scar formation. Clinically, it is commonly used as an adjuvant therapy for postoperative wounds, burns, or chronic ulcers.
4. By activating fibroblasts, red light can enhance skin elasticity, reduce fine lines and acne inflammation. Some studies have shown that it can also improve skin problems such as melasma and eczema.
