What Is Plukenetia Volubilis Seed Oil?
Plukenetia volubilis seed oil offers an abundance of skin-nourishing fatty acids, anti-ageing antioxidants, and moisturising properties due to its emollient nature. This plant oil is free of volatile fragrance compounds, which is good news for skin (because fragrance poses a risk of irritation).
Among its many beneficial compounds, Plukenetia volubilis seed oil is rich in linolenic and linoleic acids, both of which are noted in research for their skin-soothing properties and ability to help skin make more ceramides. Additionally, Plukenetia volubilis seed oil is a source of vitamin E that can help defend skin from external stressors.
Native to Peru, Sacha inchi is another name for the Plukenetia volubilis plant. It may also be referred to as mountain peanut, Inca peanut, or wild peanut.
Due to its edible nature and long history of use in Peru, Plukenetia volubilis seed oil is considered safe for skin. Typical use levels of this plant oil in cosmetics range from 1–5%, although larger amounts may be used depending on the type of product.
