What Is Prunus Persica Kernel Extract?
Prunus Persica Kernel Extract is derived from the kernel of the peach fruit and is rich in fatty acids and natural oils. It functions as a skin conditioning and moisturising ingredient, working to soften and hydrate the outer layers of the skin.
This ingredient is used sparingly in formulations, appearing in roughly 0.1% of skincare products. It offers a gentler, plant-based alternative to some synthetic moisturisers, though its efficacy profile is modest compared to other common humectants and emollients.
How It Works
Peach kernel extract works primarily as an emollient, meaning it sits on the skin's surface and helps to trap water, preventing transepidermal water loss. The fatty acid composition allows it to soften the stratum corneum (the outermost skin layer) and improve the overall feel of the skin.
As a natural conditioning agent, it does not penetrate deeply into the dermis; rather, it supports skin barrier function by maintaining surface hydration and reducing dryness-related roughness.
Clinical Evidence & References
Research specifically evaluating peach kernel extract in skincare formulations is limited. Much of the ingredient's use rests on traditional knowledge of plant oils and general understanding of how emollients function in skincare.
In principle, the fatty acids present should support skin hydration and barrier health, but robust clinical trials comparing this extract to established moisturisers are lacking. It is best viewed as a supplementary conditioning ingredient rather than a primary active.
How to Use
This ingredient is typically found in creams, lotions, and serums rather than lightweight formulations. It works well as part of a broader moisturising routine and can be used twice daily if incorporated into your morning and evening regimen. Pair it with other hydrating ingredients like glycerin or hyaluronic acid for optimal moisture support.
