The hospital
This site is published by Chongqing West District Hospital, a tertiary general hospital at 301 Huafu Avenue North Section, Jiulongpo District, Chongqing. Every reference to the hospital on this site means that institution.
Advertising and claims
This site names no brand of supplement, quotes no prices, and makes no claim about the category as a whole. It does not promise an outcome, does not offer an assessment, and carries no booking pressure of any kind. Every claim is attributed to what the evidence supports, and the regulatory status of the product is reported as the separate question it is.
Honesty requirements for this subject
Because a true statement about collagen is routinely used to introduce a claim about a swallowed product, this site grades the two separately, states which claims are unsupported rather than describing them as controversial, and states plainly that the products are regulated as food and hold no approved indication for skin ageing.
Reviewer and review cycle
Ke He, MD, Deputy Director and Head of Skin & Laser Aesthetics, is the medical reviewer for this site. Content is reviewed at publication and on a short cycle, because the marketing around these products changes faster than the science, and the date of the most recent review is shown on every page.
