Efficacy

Efficacy data quantifies the performance of a skincare product on specific skin parameters such as hydration, firmness, or oiliness. Efficacy testing is carried out at a third-party clinical facility under the supervision of a dermatologist and toxicologist. This data is analyzed by a statistician for clinical relevance, i.e., does the product produce a statistically meaningful effect on the skin parameter being evaluated to support the product claim hypothesis.

Our Efficacy Labels mirror the modern nutrition data panel on food products. Our focus is to drive consumer confidence by allowing everyone direct access to results from clinical trial studies that substantiate our product claims.

We believe that by publishing our efficacy data, we can establish a new reference point for both consumers and the beauty industry. Customers should expect every brand to justify its product claims with quantitative data in order to be able to objectively compare product performance and price.

Clinical data is measured on subjects by a professional technician with an instrument that quantifies the parameter. Self-assessment studies are questionnaires that subjects fill out about their experience of using a product, like polling a group of people about a question.

While our studies do collect customer feedback, we do not solely rely on such customer experience surveys, because we believe that quantitative measurements are more objective than opinions. For full transparency we also report the user experience survey results on our website.
