Red light therapy (RLT) has gained popularity for its ability to boost collagen, reduce inflammation, and support cellular energy. But to get real results, the wavelength and exposure need to be dialed in correctly.What is RLT?In a nutshell, red light therapy involves exposing the body to low-wavelength red or near-infrared light. These wavelengths penetrate the skin and are absorbed by mitochondria – the energy-producing centers of your cells – stimulating cellular repair, energy production, and tissue regeneration.The benefits of RLTRLT supports multiple aspects of wellness:Enhances mitochondrial energy production (ATP)Promotes faster wound healing and tissue repairReduces inflammation and oxidative stressImproves sleep and mood via circadian supportStimulates collagen for skin rejuvenationUnderstanding the light spectrum of devicesRed light (630–660 nm): Targets skin-level concerns like fine lines, inflammation, and collagen production.Near-infrared light (810–850 nm): Penetrates deeper to support muscle recovery, joint health, and mitochondrial function.What the research says Research suggest that:10–20 minutes/session is effective for most goalsOptimal distance is 4–12 inches from the deviceFrequency matters: 3–5x per week is ideal for most usersUse tipsUse eye protection when neededDon’t overuse – more is not always betterMake sure your device is clinically validatedEnjoy these tips and best practices!
