Pigment change after laser · separating hyperpigmentation, persistent redness and pigment loss · deciding when the skin has settled and when not to treat it again
Dr. Ke He is Deputy Director of the Plastic Surgery & Aesthetics Medical Center at Chongqing West District Hospital and head of its skin and laser aesthetic service — and she is the lead physician of this site. A core specialist formerly at the Plastic and Aesthetic Surgery Department of Xinqiao Hospital, affiliated with Army Medical University, she has worked on the clinical front line in skin laser and injectable aesthetics for more than 20 years, serving over ten thousand patients.
On this site her part is the examination that separates the three changes patients arrive with. She establishes when the session was and which areas were treated before she looks at the skin, because darkening that appeared on the day of treatment is a different problem from darkening that appeared three weeks afterwards, and because redness that persists in fair skin is read on a different timescale from redness that is settling. She compares the treated area with untreated skin in the same light, uses dermoscopy where the surface pattern is not clear to the eye, and photographs the boundary so that direction can be compared rather than remembered. Where the colour is still moving she does not treat it: she protects it, prescribes what is needed, and reviews it at an interval, because a device applied to skin that is still darkening is the commonest way the darkening becomes deeper. She declines a further laser session while the pigment is unstable, while the surface has not closed, and where the change is pigment loss rather than excess, and she says plainly that clearing it cannot be promised.

The examination decides, not the photograph
A photograph sent by message cannot show how the skin behaves in light, whether the surface has closed, or which of the three changes is present — and a patch that has lost its colour can look like a good result in a picture. The examination is what separates them, and the interval between two examinations is what shows whether the colour is still moving. That is why an assessment here usually ends in a review date rather than a treatment plan.
