Traditional Use

Evening primrose oil has been used in traditional European herbalism for hormonal balance and skin health since the 1980s when its gamma-linolenic acid content was scientifically documented. The PEG-20 version is a modern synthetic modification created to make the oil water-soluble for cosmetic formulations.
