Are laser and LED light therapy treatments good for your skin?

Light can be a powerful tool in skin care, whether it’s an LED facial or a laser treatment for acne. Light therapy can also seem a little mysterious if you’ve never done it before, because light doesn’t interact with the skin in the same obvious way as, say, a serum or moisturizer. Red and near-infrared light therapy can also help heal damaged or irritated skin. Joanna Vargas, a celebrity esthetician whose clients include Julianne Moore and Naomi Watts, said she often uses red light therapy to soothe the skin after other treatments. “I can do a really intense peel on somebody that would normally leave somebody really red for several hours, but after the peel, I can do red and infrared light and you walk out looking like a glowing angel,” she told TODAY Style.
