Our knowledge of the science of skincare makes it possible to formulate products that are both highly effective and gentle on the skin. We have a clinical programme of testing on sensitive skin. In these trials, we maximise the chance of a bad reaction by keeping the product occluded on the skin for 96 hours on people who report that they have healthy but sensitive skin. That’s how we can scientifically claim that all of our facial products are clinically approved for sensitive skin.
