Blue and red light can affect acne-causing bacteria and inflammation in clinical settings, at clinical doses. The at-home masks that use the same idea sell on that research while delivering a fraction of the light intensity, for a fraction of the exposure time studies actually used.

The research is real. The device on your bathroom shelf is not delivering it.

This is a call, not just a number: even where the underlying science has something to it, the consumer product doesn't deliver enough of it to matter. Save the few hundred pounds for something in-clinic or prescribed instead.
