Description

Can shining a red light on your face really improve acne, wrinkles, inflammation, or wound healing, or is red light therapy just an expensive skincare scam involving a slightly alarming mask? How could ordinary visible light affect cells beneath your skin, and should you trust the products filling your social media feed? Melissa and Jam investigate photobiomodulation, mitochondria, collagen, blue light, FDA clearance, and the research behind this increasingly popular wellness trend. The answer is more scientifically interesting, and more complicated, than either of them expected.
