Science
Mechanism of Action
Operating as a potent antioxidant, Pisum Sativum Protein, particularly its peptide fractions, effectively neutralizes free radicals and mitigates oxidative stress within the skin. Its film-forming capabilities contribute to enhanced moisture retention, thereby improving skin hydration and elasticity. Furthermore, it stimulates natural skin renewal and cellular regeneration, reinforcing the skin's structural integrity to reduce fine lines and support anti-aging efforts. It also plays a role in protecting collagen and elastin from protease degradation, aids in maintaining a healthy skin microbiome, and forms a protective barrier against environmental aggressors. Potential benefits include evening skin tone by reducing melanin production.

Dusting Analysis
Clinical studies indicate efficacy at concentrations of 0.1% for antioxidant protection and 2% for hydration, suggesting that this ingredient is effective at meaningful inclusion levels and not typically used merely for 'dusting'.
The Formula
Formulation
Stability
This peptide is heat stable, suitable for addition to formulations below 80ºC. Formulators should note potential peptide settling over time, necessitating proper mixing. While solubility is reduced near its isoelectric point (pH 4-5), it significantly improves at pH values outside this range, peaking at pH 8-9.
Safety
Safety Profile
While the CIR status indicates 'insufficient data' from a 2016 assessment, in vitro studies have demonstrated Pisum Sativum Peptide to be non-irritating and non-sensitizing. The FDA has also approved plant protein products as food additives, suggesting a general positive safety profile for dietary exposure.
