590 nm Light Effect on Lipid Droplets and Hormone-Sensitive Lipase

Green light therapy fat loss dose

Researched irradiated human fat with 410 nm, 457 nm, 505 nm, 530 nm, 590 nm, and 660 nm low level light. 590 nm “significantly reduced the concentration of lipid droplets” and increased lipid autophagy (broke down fat). In documenting the science of photobiomodulation, I rarely come across a study that finds significant effect at one wavelength, and no effect at nearby wavelengths. That did happen in this study. 590 nm affected fat breakdown and 505 nm did not. The abstract did not mention the other wavelengths tested. Presumably they were also insignificant, so it’s unclear why 505 nm was singled out as ineffective.

Light therapy heals with photons. A red incandescent bulb throws more heat than light, so it’s not likely to have a light therapy effect. Yes, you can use light therapy to reduce acne scars. Traumatic brain injury, Parkinson’s and dementia respond to red and infrared light therapy.

Cellulite Reduction Green Light Dose

Use green 532 nm diodes without massage or mechanical manipulation to improve the appearance of cellulite in thighs and buttocks.

Researchers treated 34 women with low-energy green light.

Subjects receives three treatments a week for 2 weeks (6).

Researchers treated subjects’ hips, thighs, a waist. Treatments lasted 30 min.

Subjects had significant:

decrease in circumference of treated areas
decrease in baseline body weight
reduction in BMI
reduction in cellulite
