What is it?

The mammalian cholesterol precursor and natural skin lipid that directly integrates into barrier lipid bilayers — with unique anti-protein-aggregation properties relevant to skin aging.

Integrates directly into stratum corneum lipid bilayers as a natural mammalian lipid, supports barrier function, and may prevent age-related protein aggregation in skin.

Key Benefits

✦
Direct Barrier Integration
As a mammalian-native lipid (not a plant sterol), lanosterol integrates seamlessly into stratum corneum lipid bilayers.
◈
Cholesterol Pathway Support
Provides the primary precursor for cholesterol biosynthesis in skin — supporting the skin's own lipid production capacity.
✧
Anti-Protein Aggregation
Research suggests lanosterol may prevent protein aggregation in skin — potentially relevant to preventing age-related skin changes.
◉
Sebum Compatibility
Naturally present in sebum — highly skin-compatible with no risk of pore-clogging or disruption of natural oil balance.

Suitable for
