I don't know how much evening primrose oil is in the supplement I take. I take the Barlean's Essential Woman and it lists evening primrose oil in the ingredients. Is it important for evening primrose to be in the refrigerator at the store. I know it's important for flaxseed oil, but wasn't for sure on the evening primrose oil.

However, I haven't been taking this supplement that long so I don't think it's the cause of the acne.
