Red light therapy for skin care

Red light therapy involves using devices that emit red or near-infrared light aimed at the skin. It is believed to reduce inflammation and boost production of collagen. Research suggests it can improve an array of skin problems, including fine lines, dark spots, redness, slow-healing wounds, scars, and acne. Unlike ultraviolet light, red light therapy isn’t associated with greater risks for skin cancer. Scientists are still determining the optimal doses of red light therapy for various skin conditions.
