What this site is for
This is patient education about sensitive 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 reacts, whether it needs treating at all, and which of several paths applies. The devices that occasionally help persistent redness are described elsewhere in this cluster, and repeating their technique here would help nobody.
The distinction the site is built on
Sensitive skin is a description rather than a diagnosis, and at least four different problems are filed under it. In the commonest, the outer layer has been left less able to keep irritants out and the treatment is to stop stripping it. In the next, a dermatosis such as rosacea or eczema produces the reactivity as one of its features, and the diagnosis has to come before the products. In a third, one specific ingredient has produced a delayed allergy that only testing or subtraction will find. In the fourth there is nothing visible on the skin at all and the sensation is reported at a lower threshold than usual. The four look alike in a mirror and answer to plans that barely overlap, which is why a routine adjusted before the kind is named tends to be adjusted repeatedly and to no effect.
What it deliberately does not do
It does not name products or brands, quote prices or dosages, or promise that any routine will settle the skin. It does not present a barrier cream as a treatment for rosacea, eczema or seborrheic dermatitis, or a device as a substitute for a diagnosis that has not been made. It does not describe procedure technique, because that belongs to the pages that cover it. And it does not treat skin that is eroded, oozing or painful, or a reaction with swelling or eye symptoms, as a product choice at any point.
The limits of a website
Nothing here can tell you whether the reaction on your own skin is a damaged barrier, a dermatosis, an allergy or a sensory threshold. That requires someone to look at the whole face rather than the part that is bothering you, to ask what is being applied and when the trouble started, and to decide whether patch testing is worth arranging — judgements that take minutes in person and cannot be made from a photograph or a paragraph. 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.
