We publish the results of the controlled consumer trials, which are available to download as a PDF from each product’s webpage. You will find a summary slide of the proven results in most product pages also. If the product is part of a range, like the Daily Range or TRIO Blemish Range, the study was conducted on using the whole range together, and is downloadable from the webpage of the complete range (like the links above). Before the consumer trial takes place, our products are challenge tested (by an independent laboratory) for a variety of metrics including: microbiology, stability, pH, packaging compatibility, general safety and compliance with UK/EU regulations.
