Science
Mechanism of Action
This extract operates as a multi-target enzymatic inhibitor. It suppresses the activity of collagenase, elastase, and hyaluronidase, effectively slowing the breakdown of the skin's structural proteins. Simultaneously, its high concentration of gallic acid and condensed tannins neutralizes reactive oxygen species (ROS) and provides SOD-like activity to prevent lipid peroxidation.
Research
Clinical Evidence
High confidence3%
Key findings
- 01 Demonstrated enzymatic inhibition rates of 37% for collagenase, 33% for elastase, and 22% for hyaluronidase at concentrations up to 5%.
- 02 Exhibited significant tyrosinase inhibition (36%) suggesting potential for evening skin tone.
- 03 Proven antimicrobial efficacy against S. aureus and P. aeruginosa and superior superoxide dismutase (SOD) mimicry in lipid protection assays.
Transparency
Dusting Analysis
While often included at trace amounts for marketing narratives, clinical data indicates that a minimum concentration of 0.5% is necessary to achieve measurable biological inhibition of aging enzymes.
The Formula
Formulation
Stability
Polyphenol stability is compromised by UV exposure and high thermal processing. Formulations should be shielded from light. Highly alkaline environments (pH > 8.0) can induce darkening.
Synergies
- Ascorbic Acid
- Tocopherol
- Hyaluronic Acid
Conflicts
- Strong oxidizers
- Iron and metal ions (chelation risk)
- Highly alkaline ingredients
Safety
Safety Profile
Generally regarded as safe for topical use; however, individuals with known nut allergies should exercise caution as the extract is derived from the pecan seed.
