Red light therapy (RLT) is a treatment that uses low wavelength red light to reportedly improve your skin’s appearance, such as reducing wrinkles, scars, redness and acne. It’s also touted to treat other medical conditions.
To date, there’s a lot of ongoing research, publication of small studies and a much discussion on the internet about the effectiveness of red light therapy for all types of health uses. Results of some studies do show some promise, but the full effectiveness of red light therapy has yet to be determined.
