Red light (especially 630–850nm wavelengths) penetrates your skin and is absorbed by your mitochondria — the “powerhouses” of your cells. This increases ATP, the energy currency your cells use to repair and regenerate.

Red light calms overactive inflammatory pathways and increases antioxidant activity. This leads to less swelling, redness, and irritation, ideal for skin, joints, and muscle recovery.

By energizing fibroblasts (collagen-making cells), red light increases collagen density and improves skin elasticity. Over time, this helps smooth wrinkles, firm skin, and reduce stretch marks.

Red light causes vasodilation — widening of blood vessels. Better circulation means your tissues receive more nutrients and oxygen, accelerating healing and reducing soreness.

Red light reduces oxidative stress and helps your skin reverse UV damage. It accelerates turnover of damaged skin cells and promotes healthier, more resilient tissue.

Red and near-infrared wavelengths can temporarily open microscopic pores in fat cells, allowing lipids to be released. This supports fat metabolism and can improve body contouring results when paired with a healthy lifestyle.

Athletes use red light because it reduces muscle fatigue and helps repair micro-tears faster. It also reduces pain by calming nerve sensitivity and lowering inflammation.
