Skincare glossary

Skin barrier

The outermost layer of your skin, responsible for keeping water in and irritants out.

Who it suits: Anyone whose skin feels tight, flaky, itchy or unusually reactive.

Why does the skin barrier matter?

When a product claims to “repair” or “strengthen,” this is the thing it's actually talking about.

Worth knowing

Not every skin concern needs another active ingredient. Sometimes the fix is simplifying your routine, not adding to it.
