The Soap Works Evening Primrose Oil Soap is a face and body soap rich in amino acids and polyunsaturates. It's recommended for treatment of dry skin. Evening Primrose oil is a good source of gamma linolenic fatty acids. These are rarer than the more plentiful linoleic fatty acids such as the one’s prevalent in olive oil. Linolenic fatty acids are purported to restore elasticity to older skin thereby reducing the appearance of wrinkles and other signs of aging. Along with evening primrose oil, other natural sources of gamma linolenics are borage oil and hemp seed oil. This soap is excellent for face and body.
