Science
Mechanism of Action
This extract operates through a dual-action approach: it inhibits pro-inflammatory cytokines such as IL-1b, IL-6, and TNF-alpha to reduce redness, while simultaneously modulating the filaggrin network. It accelerates the conversion of filaggrin into Natural Moisturizing Factors (NMF), specifically Pyrrolidone Carboxylic Acid (PCA), to provide immediate and long-term hydration reinforcement.
Research
Clinical Evidence
High confidence5%
Key findings
- 01 A 2022 study demonstrated that a 5% concentration significantly increases hydration by promoting PCA production within 4 hours and stimulating filaggrin synthesis after 24 hours.
- 02 In vivo testing confirmed significant reduction in UVB-induced erythema, highlighting its role as a potent anti-inflammatory and photo-protective agent.
Transparency
Dusting Analysis
While often included at trace amounts for its 'botanical' appeal, clinical hydration benefits require concentrations closer to 5%. Formulae containing less than 1% may provide antioxidant support but likely fail to trigger the filaggrin-to-PCA synthesis seen in clinical trials.
The Formula
Formulation
Stability
Highly susceptible to light-induced degradation and oxidation due to its polyphenol content. It is best utilized in airless packaging or stabilized within liposomal delivery systems.
Synergies
- Vitamin E (Tocopherol)
- Liposomal delivery systems
- Other Natural Moisturizing Factors (NMF)
Conflicts
- High pH environments (>8.0)
- Strong oxidizing agents
