Mechanism of Action
This peptide functions by modulating PP2A, an enzyme integral to genomic stability, DNA repair, and pathways associated with cellular senescence. It proactively prevents senescence progression by inducing cell cycle arrest and strengthening the skin's intrinsic DNA repair mechanisms. PENTAPEPTIDE-14 thereby signals the skin to activate its endogenous repair systems, stimulating regeneration and fortifying mature skin.

The Formula
Formulation
Stability
PENTAPEPTIDE-14 exhibits optimal stability around pH 3.0, with increased degradation observed at higher pH levels due to hydrolysis of peptide and disulfide bonds. Peptides are generally susceptible to degradation through deamidation, oxidation, hydrolysis, disulfide interchange, and racemization. Water can also act as a plasticizer, potentially facilitating unfolding and aggregation of protein molecules. It is crucial to avoid formulating with aldehyde-releasing substances, such as glycerol, to prevent Maillard reactions. Furthermore, it is recommended to exclude direct acids, retinoids, and strong antioxidants like vitamin C from peptide-containing blends.
Conflicts
- direct acids
- retinoids
- strong antioxidants (e.g., vitamin C)
- aldehydes (e.g., from glycerol degradation)
Safety
Safety Profile
