CurrentBody Skin LED Light Therapy Face Mask: Series 2

What "clinically proven" has to mean

LED masks are sold on before-and-after language, and the Advertising Standards Authority has been testing how much of it holds up. On 10 June 2026 it upheld a complaint about a rival device, Beauty Pie’s C-Wave mask, advertised as "clinically proven to reduce wrinkles in 4 weeks". The ASA found the product-specific studies were unpublished and carried methodological limitations: no sample-size calculation to show the sample was sufficient, no control group, and neither participants nor investigators blinded. That is the bar a claim of this shape has to clear, and it is worth holding any LED mask to it, this one included.

Why irradiance matters more than the LED count

Dose is irradiance multiplied by time, so the headline number to interrogate is the power density rather than how many bulbs are in the panel. The 30 mW/cm2 in the specification above is the manufacturer’s own figure; independent measurement has put this mask closer to 18.5 mW/cm2, which is the discrepancy noted in the drawbacks. A lower irradiance does not make a device useless, but it does mean the fixed 10-minute programme delivers less energy per session than the stated figure implies, and that the 3-5 sessions a week are doing more of the work than any single sitting.
