Hydration & barrier

Ceramides

The mortar between your skin cells — restores the barrier when it's been compromised.

What it actually does

Your barrier is built like a brick wall: skin cells are the bricks, lipids are the mortar — and ceramides make up about half of that mortar. When ceramide levels drop (from age, harsh cleansers, over-exfoliation, or just winter air), water escapes and irritants get in. Topical ceramides slot back into the structure and restore function over a few weeks.

Who it's for

Dry skin, mature skin, anyone with a compromised barrier (tight, flaky, stinging, or reactive). Essential in winter or any low-humidity environment.

How to use it

Look for them in your moisturizer rather than your serum — ceramides need a richer base to absorb properly. Pairs naturally with cholesterol and fatty acids; the classic 3:1:1 ratio is what the best barrier creams aim for.
