Randomized controlled study of a cosmetic treatment for mild acne
Clinical and Experimental Dermatology, 03/09/2012

Capitanio B et al. – Cosmetic products may offer some benefit for mild acne and still meet the requirements of the European Cosmetic Directive. In particular, the seaweed–derived oligosaccharide complexed with 0.1% zinc pyrrolidone used in this study produced a significant reduction in acne vs. a control treatment. Cosmetic companies should conduct blinded controlled trials of their product’s efficacy and publish the results.
