Science
Mechanism of Action
It primarily works by upregulating Aquaporin-3 (AQP3) to improve water and glycerol transport across cell membranes. Additionally, it promotes differentiation markers like involucrin and filaggrin for stronger epidermal barrier function.

Clinical Evidence
High confidence0.5%
Key findings
- 01 In vivo application at 0.5% showed significant improvement in skin hydration and barrier function, linked to AQP3 expression and keratinocyte differentiation.
- 02 In vitro studies (0.2-2%) demonstrated a dose-dependent increase in AQP3 mRNA and protein, enhancing water and glycerol transport.

Stability
Highly stable in aqueous systems and typically standardized to 10% Turkesterone. It is often provided in a water/butylene glycol base.
Conflicts
- Strong oxidizing agents
- Highly acidic (pH < 3.0) or highly alkaline (pH > 8.0) environments
Safety
Safety Profile
While not CIR/SCCS reviewed, it has a history of safe use in high-end cosmetic formulations. EWG rates the whole plant extract as low hazard (1), and standard proprietary testing showed it to be non-irritating and non-sensitizing.
