Visible light therapies, such as blue and red light, can benefit skin health when used appropriately. Dawn Davis, MD, explains that blue light treats acne through oxidative reactions, while red light may address acne and photoaging with antioxidative properties. However, over-the-counter light therapy products, such as masks and wands, might not be effective or safe. Davis emphasizes consulting a dermatologist to ensure treatments meet your skin’s needs and maintain safety. For personalized guidance, seek professional advice before pursuing light-based skincare solutions.
