Using red light therapy at home is straightforward, but getting it right makes the difference between seeing results and wasting your time. After two years of daily use — and plenty of trial and error — I’ve figured out what actually works. This guide covers everything from setting up your device to tracking results, with … Read more

Red light therapy is generally considered safe for most people when used correctly. Unlike UV light, it doesn’t damage DNA or cause burns. However, certain medical conditions — including pregnancy, active cancer, epilepsy, and photosensitivity disorders — require medical clearance before use. The most common side effects are mild and temporary: eye strain, headaches, or … Read more

Red light therapy works by delivering red and near-infrared light (630-850nm) to your cells. When mitochondria absorb this light, they produce more ATP (cellular energy). This energy boost helpscells repair damage, reduce inflammation, and function better. Unlike UV light, red light doesn’t damage DNA or heat tissue. Instead, it triggers natural biological processes already happening … Read more

Red light therapy (RLT), also known as photobiomodulation, is a non-invasive treatment that uses low-level wavelengths of red and near-infrared light to stimulate mitochondrial energy production. It is clinically used to improve skin health, reduce inflammation, and accelerate tissue repair without UV radiation or heat. By targeting mitochondria — the structures responsible for producing ATP … Read more
