What this site is for
This is patient education about laxity of the abdominal skin, published by Chongqing West District Hospital, a tertiary general hospital in Jiulongpo District, Chongqing. It is a concern guide rather than a procedure page: it answers why the skin stopped recoiling, whether anything needs doing about it, and which of several paths applies. The operations and the anatomy they work on are explained on the Body hub and on Dr. Mao’s own site, and repeating them here would help nobody.
The distinction the site is built on
Fat sits under the skin. Laxity is the skin itself. The two are read as one problem by almost everyone who has both, and they are treated in opposite directions: fat is removed, skin is removed, and removing fat from under loose skin leaves more skin relative to what is beneath it. Naming which of the two is producing the shape you object to is most of the decision.
What it deliberately does not do
It does not name products or brands, quote prices or dosages, or promise a result. It does not present a cream, a device or a fat-removal procedure as a way of tightening skin, because none of them removes skin. It does not give weight-loss advice, which is an individual prescription rather than website content, and it does not describe surgical technique, which belongs to the pages that cover the operations.
The limits of a website
Nothing here can tell you how much recoil your own skin has left, how much of your abdominal fold is skin, or whether a rash in it needs treating. Those answers come from someone lifting and releasing the skin, examining the fold and the wall beneath it, and reviewing your weight history. Use this site to arrive at an assessment with better questions, and treat any answer you receive here as general information rather than as advice about you.
