What is it?

A skin-identical ester-linked ceramide subtype, structurally distinguished by an omega-hydroxy fatty acid chain linked via an ester bond, mirroring one of the specialized ceramide structures found in the outer skin layers.

Contributes to the structural organization of the skin's lipid bilayers, helping maintain the ordered lamellar architecture that gives the skin barrier its water-resistance and mechanical strength.

Key Benefits

✦
Lipid Layer Organization
Its unique ester-linked structure plays a specific structural role in organizing the layered lipid architecture of the skin barrier.
◈
Barrier Strength
Contributes to the mechanical resilience of the skin barrier, supporting resistance to environmental and mechanical stress.
✧
Complementary to Other Ceramides
Works alongside other ceramide subtypes in multi-ceramide formulations to more fully replicate the skin's natural, complex lipid composition.

Suitable for

Dry skinSensitive skinBarrier-compromised skin

Main Actions

✓ Barrier repair✓ Structural support✓ Moisturising
Best in Multi-Ceramide Blends

Ceramide 4 is less commonly used alone and more often appears as part of a blend with other ceramide subtypes (like Ceramide 3 and Ceramide 6-II), since the skin barrier naturally relies on multiple ceramide types working together rather than a single subtype.
