“Red light therapy offers multiple benefits for both health and skin quality. From a medical perspective, it promotes tissue regeneration, supports wound and burn healing, and helps relieve muscular inflammation. From an aesthetic standpoint, it improves skin radiance, reduces redness, and helps manage inflammatory acne, rosacea, and sensitive skin.”

“Red light therapy (RLT) is an innovative technique that can promote healing and reduce recovery time. Thanks to its ability to stimulate cellular regeneration, decrease inflammation, and enhance overall healing, this non-invasive treatment has gained significant medical recognition.”

“Exposure to artificial light at night is one of the main disruptors of healthy sleep. Red-lens glasses help block sleep-disrupting wavelengths, allowing the brain to maintain natural melatonin production. As a result, patients experience faster sleep onset, deeper rest, and improved overall sleep quality.”
