What is it?

A negatively charged phospholipid from cell membranes that supports cell signaling, membrane integrity, and ceramide synthesis in aging skin.

Restores phospholipid membrane composition in aging skin, supports PKC cell signaling, and provides serine for ceramide biosynthesis — improving barrier function.

Key Benefits

✦
Membrane Integrity Restoration
Replenishes the phospholipid composition of aging cell membranes, restoring optimal membrane fluidity and function.
◈
Cell Signaling Support
As a key cofactor for PKC activation, PS supports multiple membrane-dependent cell signaling pathways.
✧
Ceramide Precursor
Provides serine substrate for de novo ceramide synthesis, supporting skin barrier lipid production.
◉
Moisturization
Integrates into membrane bilayers and improves skin's water-binding capacity and moisture retention.

Suitable for

Mature skinBarrier-compromised skinDry skinAnti-aging routines

Main Actions

✓ Membrane lipid restoration✓ Cell signaling support✓ Barrier lipid support✓ Moisturizing
Usage Note

Phosphatidylserine is often paired with phosphatidylcholine and ceramides in advanced barrier repair formulas. It is well tolerated and shows no significant sensitization potential. Most commonly found in premium anti-aging moisturizers.
