Science
Mechanism of Action
This ingredient functions as a biological mimetic of the FOXO3a transcription factor, often referred to as the 'longevity gene,' which triggers DNA repair and cellular renewal. It provides multi-pathway protection by neutralizing free radicals as an antioxidant, chelating metal ions to prevent oxidative stress, and inhibiting Matrix Metalloproteinase-1 (MMP-1) to protect existing collagen while stimulating the COL1A1 gene for new fiber production.
Research
Clinical Evidence
Medium confidence0.05%
Key findings
- 01 In vitro testing at 0.05% concentration demonstrated a 38.44% increase in COL1A1 mRNA expression and a 21.05% reduction in collagen-degrading MMP1 mRNA.
- 02 In vivo human trials using an encapsulated delivery system showed a nearly 10% reduction in wrinkle depth within 14 days, improving to 10.82% after 4 weeks.

Dusting Analysis
Because peptides are effective at very low concentrations, they are frequently 'dusted' at negligible levels for marketing claims. While bioactivity is seen at 0.05%, formulas containing less than 0.01% are unlikely to provide the cellular longevity benefits identified in clinical data.
The Formula
Formulation
Stability
Optimal stability is maintained in water-based solutions at a near-neutral pH. To maximize transdermal delivery, it is best formulated within nanoethosomes or liposomal carriers.
Synergies
- Hyaluronic acid
- Other non-acidic peptides
