Science
Mechanism of Action
This extract stimulates the synthesis of essential structural proteins, including Collagen-1, Filaggrin, and Involucrin, which strengthens the dermal-epidermal junction to provide mechanical support for pore walls. Additionally, it modulates sebocyte metabolism to reduce excess oil and regulates inflammatory markers like stratifin to combat age-related skin degradation.

Clinical Evidence
High confidence3%
Key findings
- 01 In a 4-week clinical trial at 3%, 93% of participants reported smoother pores and 90% observed a reduction in skin shininess.
- 02 Instrumental analysis confirmed a reduction in pore surface area by up to 90% and pore volume by up to 94% after 28 days of twice-daily use.
- 03 In vitro data shows significant antioxidant capacity and inhibition of lipid peroxidation at concentrations as low as 0.15%.
Transparency
Dusting Analysis
While it provides antioxidant protection at very low levels, the clinically validated 'pore-tightening' and 'skin architect' effects require a 3% concentration. Formulations using it below 1% are likely leveraging it for label claims rather than structural transformation.
The Formula
Formulation
Stability
Highly sensitive to thermal degradation; must be incorporated during the cool-down phase of formulation. Supercritical CO2 extraction is preferred to maintain the integrity of volatile phthalides.
Synergies
- Linum Usitatissimum (Linseed) Seed Extract
- Niacinamide
- Peptides
Conflicts
- Strong oxidizing agents
- High-heat processing
Safety
Safety Profile
Recognized as FDA GRAS for food consumption. While celery contains trace furanocoumarins which can be photosensitizing, modern supercritical extraction methods typically minimize these to negligible levels.
