Oenothera Biennis Oil description

_Oenothera biennis_ oil, more commonly known as evening primrose oil, comes from a plant with yellow flowers that is native to North America.

Research demonstrates that _Oenothera biennis_ oil has high value when it comes to its inclusion in skin care products. Because it is a plant extract, it has antioxidant benefits, primarily through its high vitamin E content.

In fact, evening primrose oil boasts an impressive 74% concentration of linolenic acid! Use of _Oenothera biennis_ oil in tests has shown an increase in barrier function and moisture, even in people with skin conditions such as eczema. In short, this non-fragrant plant oil is an excellent addition to any skin care product. Typical use levels of evening primrose oil in cosmetics range from 0.1–20%. It is considered safe as used in cosmetics as well as when used as an oral supplement (but note to discuss all supplements with your health care provider before use).
