$$$ Olive Oil Polyphenols Hydrating Nutrient Mask ($65 for 2 ounces) is, with the exception of olive oil, short on significant amounts of antioxidants. Since this product is packaged in a jar and, therefore, is not airtight, the effectiveness of the small amount of antioxidants present is lost soon after the product is opened. It contains plenty of rich emollients and certainly can help make dryness less of a problem. However, considering you can get similar benefits from plain olive oil or evening primrose oil, and the lack of airtight packaging, I suggest thinking twice before investing in this product.
