Science
Mechanism of Action
Functions as a Peroxisome Proliferator-Activated Receptor-alpha (PPARα) agonist, triggering enhanced collagen synthesis pathways while inhibiting matrix metalloproteinase-1 activity. Additionally modulates fibroblast secretome to reduce melanin production and optimize keratinocyte differentiation, while providing protective effects against UV-induced cellular stress markers including p53 activation.

Clinical Evidence
High confidence0.1%
Transparency
Dusting Analysis
Given the demonstrated efficacy at 0.1% concentration and the precision required for PPARα activation, concentrations below 0.05% would likely provide minimal benefit and constitute dusting of this active ingredient.
The Formula
Formulation
Stability
Solid fatty acid at room temperature (melting point 81-86°C) requiring heated incorporation into oil phase. Demonstrates stability in oil-in-water emulsions when properly solubilized.
Synergies
- retinoids
Conflicts
- strong oxidizing agents
- cationic surfactants
- formulations below pH 4.5
Safety
Safety Profile
CIR reviewed in 2019 under fatty acids assessment with previous evaluations in 1999 and 2015 confirming safety. Maximum reported concentration of 13.2% in leave-on products, though active benefits typically achieved at 0.1-1.0%.
Our Assessment
Verdict
Well-researched bioactive fatty acid with impressive collagen stimulation data and multi-target anti-aging benefits at low, cost-effective concentrations.
