We analyse all of the latest research to show you the evidence on what actually works.
When evaluating the potential of a skincare ingredient or product, we ask - and show you the answers to - the following questions.
Is the active ingredient stable when exposed to light, heat, water and oxygen? Does it remain stable over time?
Can the active ingredient penetrate the skin barrier? If not, are there ways to enhance its absorption?
Can the active ingredient be delivered in sufficient concentrations to its intended target in the skin?
Does the active ingredient have known, specific biochemical mechanisms of action in its target cell or tissue?
Are there published, peer-reviewed studies and clinical trials to support the claims that the active ingredient is effective?
Are there reports of the active ingredient causing any temporary or permanent side effects?
