What is the optimal dose for red light therapy? Can you have too much red light therapy? Are bigger doses always more effective? What happens when you overdose red light therapy? This blog reviews some clinical studies that show humans can be overdosed with red light therapy. We introduce optimal dosing ranges and methods to help make sure dosing is as safe and effective as possible.

For years, 100 mW/cm^2 has been claimed to be the best intensity for red light therapy. We look through the evidence in the literature, and listen closely to real researchers to find the truth - which has been obscured by years of lies from fake experts. We propose that 10 to 50 mW/cm^2 is the appropriate intensity range for large LED panel red light therapy. And that 100mW/cm^2 is not ideal, but often considered the upper limit where detrimental effects can occur.

How do Red and Near-Infrared light wavelengths affect melanin production in the skin? Can they cause hyperpigmentation or exaserbate melasma? What about other photobiomodulation wavelengths like Blue, Green, Yellow? Does heat play a role in causing a pigmentation response? While Sunlight and UltraViolet (UV) light are known to affect skin pigment through tanning, recent studies have looked into the influence of other wavelengths of light on skin pigmentation response. The popularity of Red and Near-Infrared LED panels and many other types of light therapies at home has led to questions if it would affect or worsen hyperpigmentation conditions and melasma,...

Red and Near-Infrared wavelengths of light are known to penetrate the deepest into the skin out of the entire sunlight spectrum. However, can they reach important target tissues like muscles, bones, internal organs, and the brain? If they don't, can it have any effect on them? Such questions would cast doubt on the efficacy of red light therapy. Often LED application can't reach very deep, Red wavelengths lack penetration, and not implementing skin contact method will severely limit penetration. If the photons can't reach the target cells, many assume there would be no effect or benefit. Photon Penetration vs Deeper...

In his latest reviews, Alex Fergus exposes many of the top red light therapy brands for their table top models. Let's take a look at Alex's intensity measurements and how they compare to their advertised intensity. So no surprise that again there is nearly a 100% difference across all these major brands. The advertised intensity claims may be inflated by about 2x of what the reality they are actually delivering at 6 inches away. FDA Class II Risk vs Low Risk Photobiomodulation The top panels like Joovv, PlatinumLED, and Mito Red Light are all FDA Registered (not FDA Approved) as...
