What this site is for
It exists to separate the products that share a name from the evidence that does not, and to grade each honestly rather than presenting the category at the level of its best-studied member. That is why every claim is placed in one of four groups, why the category is described as a way of placing a substance rather than as a product class, and why approval is reported per product and per market.
What it deliberately does not do
It does not recommend for or against any product, 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 does not name brands, does not quote prices, and does not dismiss the whole category on the grounds that its weakest members are poorly evidenced.
The facts kept visible
Three facts are repeated wherever they are relevant. The category is defined by placement rather than by content, so its members are not interchangeable. Evidence belongs to a product and an indication, which means a finding for one member is not a finding for the group. And approval is granted market by market, so a product approved elsewhere is not thereby approved here.
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 on two fast clocks, because approvals change market by market and the category keeps acquiring new members, 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 If you find something unclear, out of date or wrong, the contact page explains how to tell us, and the correction is made to the page itself.
