Science
Mechanism of Action
Works through three complementary pathways: natural lactic acid content provides gentle AHA exfoliation by dissolving intercellular connections, high-quality milk proteins (casein and whey) form protective films that minimize water loss, and specialized milk fat globule membrane phospholipids and sphingolipids integrate with skin's lipid barrier to enhance repair processes and moisture retention.
Research
Clinical Evidence
Medium confidence1%
Key findings
- 01 Human study (n=40) showed 1% milk sphingolipid-enriched fraction significantly increased hydration and accelerated barrier recovery
- 02 Research demonstrated glucocerebroside-containing buttermilk inhibited UVB photoaging while stimulating hyaluronic acid and ceramide synthesis

Dusting Analysis
Not typically subject to dusting practices due to its established efficacy profile and legitimate multifunctional benefits in skincare formulations.
The Formula
Formulation
Stability
Requires robust preservation systems due to protein and lactose content creating microbial growth risk. Avoid isoelectric point around pH 4.6 where protein precipitation occurs.
Conflicts
- High electrolyte concentrations
- Strongly acidic environments below pH 4.5
- Excessive heat above 60°C for extended periods
Safety
Safety Profile
Primary safety consideration relates to lactic acid content potentially increasing photosensitivity when acid concentrations exceed 10% or pH drops below 3.5. Generally well-tolerated across skin types.
