Red light therapy (RLT) is a treatment that uses low-level red or near-infrared light to improve healing, reduce inflammation, and boost skin and cell health.

It works by stimulating cellular energy (ATP) in your body. It’s non-invasive, generally safe, and painless, with few side effects.

Common Uses: skin rejuvenation (anti-aging, acne), pain and inflammation relief, hair growth, wound healing.

Red light therapy is generally considered safe when used correctly. It’s non-invasive, painless, and has very few side effects. That said, like any treatment, it’s not completely without risk.

Safe Use Tips:

Follow the manufacturer’s guidelines

(time, distance, frequency)

Don’t overexpose—more is not better

Use eye protection if light is near the eyes

Avoid using on open wounds or active skin infections without medical advice.

 

If you have a medical condition, are pregnant, or take medications that make your skin sensitive to light (like some antibiotics or acne meds), it’s best to check with a doctor first.

Red and near-infrared light (typically in the 600–1000 nm wavelength range) is absorbed by the mitochondria in cells.

This enhances cellular energy production (ATP), which may help with:

Reducing inflammation, promoting healing and tissue repair, stimulating collagen production, improving circulation

 

Common Uses:

Skin health (anti-aging, acne, wound healing)

Joint and muscle pain relief

Hair growth (e.g., in androgenic alopecia)

Reducing inflammation

Speeding up injury recovery

Improving mood and sleep (in some cases)
