Common Name(s): Mare milk lipids,equine milk fat,koumiss lipids

DESCRIPTION

What It Does: Conditions skin with lipids naturally similar to human skin barrier lipids from mare's milk.

Why It's Used: Mare's milk lipids have unusually high phospholipid fraction (~20-25% of lipids) including phosphatidylcholine and sphingomyelin — making it more similar to human skin barrier lipids than other animal milks.

How It Works: High phospholipid (pc, sm) and sphingolipid content mimics human stratum corneum lipid composition; equine milk linoleic acid content (~25% of fatty acids) matches skin surface lipid profile; sphingomyelin supports ceramide pathway.

Typically Found In: Luxury skin care,barrier support products,premium equine formulas

TECHNICAL DETAILS

Primary Category: Functional ingredient – emollient

Secondary Functions: Skin conditioning,barrier support

Application Areas:

Typical Concentration Range: 0.5%–5%

SOURCING & ETHICS

Vegan Status: No - animal-derived

Halal Status: Conditional - dairy or egg origin statement required, plus rennet and enzyme origin upstream

Source Notes: Derived from mare's milk; equine (animal) origin. [audit 2026-07-29 rev2: dairy or egg protein; rennet and enzyme origin upstream are undocumented. determination requires shariah-panel sign-off.]

SKIN COMPATIBILITY

Irritancy Rating: 1/5 – very low

Comedogenicity Rating: 1/5 – low

Sensitivity Concerns: Generally well tolerated.

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

Safety Profile: Good safety profile. ewg score: 1.

Works Well With: Ceramides,phospholipids,cholesterol

Avoid Combining With: No significant incompatibilities

SCIENTIFIC NOTE

Mare's milk phospholipid fraction is uniquely close to human milk in composition; the high sphingomyelin content relates to its proposed skin barrier support properties; used in premium european equine-derived skin care formulations.
