What Is Plukenetia Volubilis Seed Extract?
Plukenetia volubilis seed extract comes from sacha inchi, a plant native to the Amazon rainforest. The seeds are nutrient-dense, containing omega fatty acids, proteins, vitamin E, polyphenols, and amino acids. When extracted, these compounds are incorporated into skincare formulations primarily for their skin-conditioning properties.
The extract works as an emollient and antioxidant agent. Traditional use in South American communities has centred on topical application for skin softening and healing, though modern cosmetic use focuses on the ingredient's ability to condition and protect the skin barrier.
How It Works
The seed extract contains two main active components: polyphenols (including procyanidins and flavonoids) and polyunsaturated fatty acids. The polyphenols function as antioxidants, binding to unstable free radicals and preventing them from damaging skin cells. This is thought to reduce oxidative stress, a contributor to premature ageing.
The fatty acids and proteins coat the skin surface, creating a conditioning layer that softens the skin and helps it retain moisture. Together, these components work to improve skin feel and support the skin's natural protective barrier, though the extent of these effects in finished skincare products depends on concentration and formulation.
Clinical Evidence & References
Research on sacha inchi seed components shows promise. Studies have demonstrated that seed shell extracts possess antioxidant potential, with ethanolic extracts showing particularly strong activity—attributed to their higher phenolic and procyanidin content. The seeds have also shown antibacterial properties in laboratory settings.
However, most research to date has focused on the seed's nutritional and pharmaceutical applications rather than its use in topical skincare. Clinical evidence specifically evaluating this extract in cosmetic formulations on human skin is limited. Whilst traditional use supports its skin-conditioning role, further research would help clarify its efficacy in modern skincare products at typical concentrations.
How to Use
Plukenetia volubilis seed extract is typically used as a supporting ingredient within broader formulations rather than as a standalone treatment. It works well in moisturisers, serums, and conditioning masks. As with any skincare ingredient, introduce it gradually if you have sensitive skin, and use consistently over several weeks to assess its effect on your skin condition.
