Korean skin treatment glossary

Treatment names used in a Korea beauty clinic often differ from the ones used elsewhere. Shurink, Rejuran and Juvelook are everyday words in Seoul and almost unknown abroad. This page gives a plain one-line definition for each, so you know what is being offered before you sit down for a consultation at a Seoul skincare clinic.

Each term links to its full entry, where the columns and studies that mention it are collected. Entries are written in Korean; the definitions here are summaries.
