What this site is for

It exists to let a patient tell ordinary healing from a problem, and to make the problems that cannot wait unmistakable. That is why the red-flag routing sits above every explanation on this page, and why the actions attached to each sign are written to be read in seconds rather than studied. It is a triage guide, not a catalogue of everything that can go wrong.

What it deliberately does not do

It does not name brands of devices, needles or skincare products: treatments are described by technology class only. It does not quote prices or settings, and it does not promise that a burn, a scar or a pigment change can be reversed. It does not publish an emergency telephone number, a room number or a set of opening hours of its own, because a number printed on a website can be wrong at the moment it is needed most.

The facts kept visible

Three facts are repeated wherever they are relevant. Heat delivered at depth can injure skin and can affect the fat beneath it. Loss of pigment after an energy injury may not recover, which is not the same as darkening that often settles. And repeating the same treatment on skin that has already been injured is usually the wrong answer, which is why any further treatment is planned from what the skin now is.

How the content is reviewed and corrected

Ke He, MD, Deputy Director and Head of Skin & Laser Aesthetics, is the responsible physician. Every guide is reviewed against her clinical judgement before publication and reviewed again on a six-month cycle. If you find something unclear, out of date or wrong, the contact page explains how to tell us, and corrections are made to the page itself.
