Red light therapy (RLT) is a treatment that uses low-level wavelengths of red or near-infrared light to stimulate biological processes in the body, primarily by acting on mitochondria, the energy-producing structures within cells. This stimulation increases cellular energy production (ATP), which enhances cell function, repair, and regeneration
What Red Light Therapy Does
- Skin Health and Rejuvenation : RLT promotes skin healing by increasing collagen and fibroblast production, which improves skin elasticity, reduces wrinkles, and helps with conditions like acne, psoriasis, eczema, and minor wounds. It also increases blood flow and reduces redness and inflammation in the skin
- Pain and Inflammation Reduction : By boosting cellular energy and promoting healing, RLT can reduce inflammation and relieve pain in muscles, joints, and tissues. It is used for muscle pain, joint pain, pain related to chemotherapy, and chronic conditions like fibromyalgia and osteoarthritis
- Wound Healing and Tissue Repair : RLT accelerates wound healing and tissue repair by stimulating new blood vessel formation (angiogenesis) and enhancing cell regeneration
- Hair Growth : Some forms of RLT may support hair growth by stimulating hair follicles
- Cognitive Function : Emerging research suggests that near-infrared light therapy applied to the brain may improve cognitive function in people with dementia, though more studies are needed
How It Works
Red light penetrates the skin without generating heat or UV damage. It is absorbed by mitochondria, which then produce more ATP, giving cells more energy to perform repair and rejuvenation functions. This process can increase collagen production, improve circulation, reduce inflammation, and stimulate cellular growth
Safety and Side Effects
RLT is generally safe with a low risk of side effects when used properly. Overexposure or misuse, especially with high-intensity devices, can cause skin burns or eye damage. It is non-invasive and painless, making it a popular alternative or complementary treatment for various conditions
. In summary, red light therapy enhances cellular energy production to promote skin healing, reduce inflammation and pain, support tissue repair, and potentially improve cognitive function, with a growing but still emerging evidence base supporting its benefits
