Do Those Friday the 13th-Like LED Face Masks Work? A Doctor Explains

The UK banned ads for some LED face masks after finding unauthorized medical claims.

Clinical evidence suggests at-home LED masks can help acne and skin rejuvenation, but results depend on the device, wavelength, and dose.

Experts say the bigger problem is marketing that promises more than these products can reliably deliver.

Red, blue, and near-infrared light may have benefits, but not all masks are supported equally by real-world data.
