Science
Mechanism of Action
This extract operates through a multi-pathway approach to epidermal integrity: it stimulates the production of essential lipids—including ceramides, cholesterol, and free fatty acids—within the stratum corneum to reinforce corneocyte cohesion. Additionally, it accelerates cellular renewal and the synthesis of Natural Moisturizing Factors (NMF), while providing secondary benefits by inhibiting tyrosinase activity to modulate melanin production.

Key findings
- 01 Demonstrated significant replenishment of the hydrolipidic film and strengthening of the skin barrier through enhanced lipid synthesis.
- 02 Observed measurable antioxidant activity and inhibition of melanin production via tyrosinase suppression.

Dusting Analysis
As a plant cell extract often dispersed in carrier oils like sunflower oil, it is frequently used at very low 'claim' concentrations in mass-market products. To see physiological barrier benefits, it should be positioned alongside other barrier-identical lipids.
