Research and Studies

Over the past two decades, hundreds of studies have explored how red light affects the body. This area of science is known as photobiomodulation (PBM). While every study uses its own setup, timing, and light levels, many report that red light may help support natural recovery and performance processes in the body.

Exercise and recovery

Research on muscle recovery suggests that red light used after exercise may help reduce soreness and support faster return to normal function. Results depend on how much light is used and the duration of exposure. Read a review on red light and muscle recovery.

Skin and appearance

Red light has been studied for its effects on skin quality and texture. Studies suggest it may encourage healthier-looking skin by influencing surface and sub-surface biological processes. See an overview on red light and skin health.

Joints and movement

Red light has been tested in studies involving knees, hands, and jaw joints (TMJ). Some trials have reported reduced discomfort and improved motion when light is applied in controlled settings. Example: plantar fasciitis research. Example: tendon studies. Example: TMJ study.

Wound and tissue support

Early laboratory and clinical studies have examined red light’s role in supporting tissue health and repair. While findings are varied, red light continues to be an active area of research for cellular energy and healing responses. Read an example of wound-healing research.

Knee and joint health

Several controlled studies have explored red light exposure and knee comfort in participants with mild or moderate joint issues. Some reported improvements in movement or reduced perceived pain. Read summary on knee studies.

How this informs Rejuvulite

Rejuvulite’s design was inspired by the research ranges commonly reported in photobiomodulation studies—balancing intensity, session time, and wavelength (630 nm red) for practical at-home use. For technical specifications, see the Dosing page.
