The UK’s Advertising Standards Authority (ASA) has banned Beauty Pie’s claim that its C-Wave Facial LED Treatment Mask “clinically proven to reduce wrinkles in 4 weeks.” The regulator found the evidence insufficient for the advertising campaign used on the London Underground.
Beauty Pie presented two studies specific to their mask and six on similar LED technologies. However, the ASA identified methodological flaws in the product-specific research. These included small participant numbers, a lack of control groups, and no blinding of participants or researchers. These issues prevented the ASA from accepting the results as reliable proof.
Furthermore, the supporting studies on other LED devices examined different equipment, treatment protocols, and usage conditions. The ASA concluded this external data could not validate the specific claims made about the Beauty Pie mask’s ability to reduce wrinkles within a four-week period.
This ruling directly impacts salons and beauty businesses promoting advanced treatments. It reinforces the ASA’s stance: robust, product-specific clinical data is essential before making scientific or performance claims. Relying on general LED technology studies or research with methodological weaknesses is no longer acceptable. Businesses must ensure any efficacy claims are backed by studies that directly support the product and its stated benefits.
