What this site is for
It exists to grade prevention claims honestly in a subject where the claims are hardest to test and easiest to sell. That is why every claim is placed in one of four groups, why the structural problem with the whole category is set out before any individual claim, and why the two preventive measures with real evidence behind them are placed first rather than treated as an afterthought.
What it deliberately does not do
It does not recommend for or against any treatment, and it does not invite a reader toward an assessment or a consultation. It is not a booking page and it offers no service in relation to anything it describes. It also does not tell a reader who wants treatment early that they are mistaken: it sets out what can be demonstrated and what cannot, and leaves the decision where it belongs.
The facts kept visible
Three facts are repeated wherever they are relevant. A face with no findings has no measurable baseline, so a benefit cannot be shown while the risks remain real. Nothing is approved with a preventive indication for facial ageing. And sun protection and not smoking are the only preventive measures in this subject with substantial support, neither of which requires a clinical treatment.
How the content is reviewed and corrected
Ke He, MD, Deputy Director and Head of Skin & Laser Aesthetics, is the responsible physician. This subject moves far faster in its marketing than in its evidence, so the review is dated and revisited on a short cycle rather than treated as a settled text. If you find something unclear, out of date or wrong, the contact page explains how to tell us, and the correction is made to the page itself.
