Benefits of Light Therapy For Your Skin
According to board-certified dermatologist Dr. Melanie Palm, the treatment works through different wavelengths of LED light to pe*****te the skin at different depths to effectively combat acne, inflammation, swelling, signs of aging, collagen production, rosacea, and even minor wounds. Keep in mind that these work best to supplement a well-rounded routine of in-office treatments, a thorough skin-care routine, and consistent use.
What color light therapy do you need?
Choose the light therapy color based on your desired results. “For example, someone with acne-prone skin might consider adding bacteria-killing blue-light therapy into their blemish-fighting skin-care routine, which would already include steps like cleansing, toning, and using topical acne-fighting serums formulated with retinol or AHAs/BHAs,” advises Dr. Palm. Below, more on the benefits of the most popular light therapy wavelengths.
Red: Red light is the most popular wavelength—“often used for anti-aging benefits as it has been shown to stimulate collagen production as well as decreasing inflammation, promoting healing and improving circulation,” per Murphy-Rose.
Infrared: “Near-infrared light has similar benefits as red light therapy but pe*****tes deeper into the skin,” Murphy-Rose continues. It is often considered a more powerful treatment for wrinkles and skin elasticity.
Blue: Blue light is a solid acne treatment as this light wavelength has anti-bacterial and anti-inflammatory properties which kills acne-causing bacteria.
Yellow: “Yellow light is thought to help reduce redness, inflammation, and irritation,” says board-certified dermatologist Dr. Mina Amin.
Bid adieu to acne, fine lines, and discoloration.
