Least Heating Wavelengths for Red Light Therapy: Best Penetration?

Least Heating Wavelengths for Red Light Therapy: Best Penetration?

Which wavelengths are the least heating for red light therapy? Is it Red or Near-Infrared that produce the least heat on the skin? Can the least heating wavelengths tell us which ones have the best penetration? The basic premise and definition for Photobiomodulation (PBM) and Low Level Laser/Light Therapy (LLLT) has been that it is the science of the non-thermal interaction of light on biology. [1] The Red to Near-Infrared wavelength range from 600nm to 1100nm are typically considered to be the "optical window" of the skin that not only penetrate deepest into the skin compared to the rest of...

Too Much Red Light Therapy? Optimal Dosing Models

Too Much Red Light Therapy? Optimal Dosing Models
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.

The Best Intensity 100 mW/cm^2 for Red Light Therapy: Where is the Data?

The Best Intensity 100 mW/cm^2 for Red Light Therapy: Where is the Data?
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.

The Science of Light Therapy on Melasma and Hyperpigmentation

The Science of Light Therapy on Melasma and Hyperpigmentation

How do Red and Near-Infrared light wavelengths affect melanin production in the skin? Can they cause hyperpigmentation or exacerbate 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,...

Deepest Penetration Red Light Therapy: Systemic Effects for Brain, Organ, and Deep Tissue Treatments

Deepest Penetration Red Light Therapy: Systemic Effects for Brain, Organ, and Deep Tissue Treatments

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...
