Melrose Organic Evening Primrose Oil is cold-pressed from the seeds of the evening primrose flower, which blooms only at sunset. It is a rich source of gamma-linolenic acid (GLA); a unique omega-6 fatty acid that assists in the production of hormones necessary for many important bodily functions. Evening Primrose Oil has been used traditionally to help with skin, scalp and hair health. It can be used topically to help nourish and moisturise the skin.
