What Is Hydrolyzed Pea?
Hydrolyzed pea is a conditioning agent derived from pea plant proteins that have been broken down into smaller molecular fragments. This process increases their ability to penetrate and interact with the skin's outer layers.
In skincare formulations, hydrolyzed pea functions as a humectant and film-former, helping to draw moisture into the skin and lock it in place. It also provides a lightweight conditioning effect without the heaviness of some heavier plant proteins.
How It Works
Hydrolyzed pea contains amino acids and polypeptides that work on two levels. First, as a humectant, these fragments attract and bind water molecules from the environment and deeper skin layers, pulling hydration to the surface. Second, they form a thin conditioning film on the skin that reduces water evaporation.
The protein fragments are small enough to be absorbed into the stratum corneum (the skin's outer layer), where they help reinforce the skin's natural moisture-retention mechanisms.
Clinical Evidence & References
Research on hydrolyzed plant proteins suggests they are effective skin conditioners with humectant properties. The evidence base for hydrolyzed pea specifically is limited, though it aligns with broader findings on hydrolyzed proteins and their ability to improve skin hydration and elasticity.
Most data comes from in vitro and sensory studies rather than large-scale clinical trials. The ingredient appears well-tolerated across skin types, but further research would help establish specific efficacy thresholds and optimal concentrations.
How to Use
Hydrolyzed pea works well in serums, essences, and lightweight moisturisers. It pairs effectively with other humectants like glycerin and hyaluronic acid, where the combination can amplify hydration benefits. Apply to damp skin to maximise its moisture-binding properties.
