​​​​Red light therapy, also called "Photobiomodulation" uses specific wavelengths of visible red and near-infrared light. Those photons are absorbed by mitochondria, the energy centers of your cells. The result, shown across decades of research, is more cellular energy (ATP), better local circulation, and calmer inflammatory signaling.

​

The ST300 uses both workhorse wavelengths:

• 660 nm (visible red) — works in the skin and upper dermis for tone, collagen support, and surface recovery

• 850 nm (near-infrared) — invisible light that reaches deeper into muscle, joints, and connective tissue

 

Together they treat more than one layer of the body in a single session.

We stopped living in the sun!

​

Most of the day now happens indoors: offices, cars, screens, glass. Window glass and indoor lighting strip out the outdoor spectrum. You lose midday UVB that makes vitamin D. You also lose the strong red and near-infrared load that natural sunlight carries. The ST300 puts back one thing modern indoor life removed: a concentrated, non-UV dose of the same red and near-infrared wavelengths used in photobiomodulation research.

 

What the research supports

​

Evidence is strongest for:

• Skin quality — collagen density, fine lines, roughness, and tone

• Wound and ulcer support — faster area reduction in multiple clinical trials

• Hair density in androgenetic thinning

• Muscle recovery and delayed-onset soreness

• Joint and musculoskeletal comfort, including knee osteoarthritis and neck pain

• Support for peripheral neuropathy and diabetic-foot-related discomfort

• Adjunct care for radiation dermatitis in clinical settings
