The Research · Peer-Reviewed

The science behind the light.

Photobiomodulation (red light therapy) is backed by a large and growing body of independent, peer-reviewed research. Below is a plain list of studies — sourced directly from published journals, not written or funded by me — so you can read the original research for yourself. Click any title to go straight to the source.

Independently Published

MedWave's work sits in four clinical areas, and the studies below span all of them: Pain & Inflammation · Aesthetics & Fat Loss · Wound Care & Tissue Repair · Neurological Health. Several of the newest entries bear directly on women's health — skin and collagen, metabolic rate in women, and sleep. A study appearing here means it was published and peer-reviewed — not that it describes the treatment you would receive, or predicts your result.

2026
Photobiomodulation in Skin: Collagen, Repair and Photoageing

Light in the 630–810nm band — the range the Neuro-100S works in — acting on fibroblasts, keratinocytes and the endothelial cells lining small blood vessels. Links this to collagen synthesis, fibroblast proliferation, growth-factor upregulation and new blood supply. Forum Dermatologicum 2026;12:e05026036

2025
Photobiomodulation and Resting Energy Expenditure in Women with Obesity

A single photobiomodulation exposure raised resting energy expenditure — the body using energy more efficiently — without changing which fuel it burned. The authors put it forward as a promising non-invasive adjunct for metabolic health in women, alongside diet and movement rather than instead of them. De Nardi M, Allemano S, Buratti M, et al.
