How Red Light Therapy Became Big Business for Beauty Brands

Red light therapy is becoming a popular skincare solution, with promises to reduce inflammation, minimize acne and wrinkles, and boost collagen recovery. In the last four months, searches for “red light therapy” have surged by 123% on TikTok, according to the platform. Gen Zs and millennials are driving demand for health devices and tech tools in their routines, according to McKinsey, but specialists say red light therapy spans generations. From specialized players like CurrentBody — which sells red light devices for face, hair, neck and décolletage, hands and more — to beauty giants like L’Oréal Group, which is rolling out its first red light tools next year. The brand’s LED Light Therapy Mask was featured in the opening scene of season two of Emily in Paris.
