**Correspondence**

A precise correction is useful. The disputed sentence and the relevant study give it somewhere to land.

## Correspondence status

This edition has no public inbox or connected message form. This page receives no submissions, and the site cannot answer personal treatment questions. The [about page](/about) explains the publication’s scope.

A dead address would be a poor substitute for that plain statement.

## A correction’s useful details

A useful correction identifies the page path, the exact passage and the relevant paper. A study title, DOI or PubMed identifier helps distinguish a factual mistake from a disagreement about interpretation. The [reading list](/references) supplies the sources used in these essays.

For a numerical correction, the population, unit and outcome are as useful as the number. For an interpretation, the distinction at issue matters: retained copper, a response in cultured cells or a visible skin finding. Evidence that clarifies those relationships would be welcome.

LumiDerm Skin Clinic is my notebook of published research on ingredients’ chemical afterlives; it is not a business and offers no medical advice.
