A lightweight fixed vegetable oil expressed from cucumber seeds. It functions primarily as an emollient and skin-conditioning oil, with a fatty-acid profile typically rich in linoleic acid and containing oleic acid, tocopherols, and phytosterols. In skincare it is used to soften skin, reduce dryness, and support a comfortable, non-greasy feel in leave-on products.

Main concerns are rare contact sensitivity to botanical oils, potential oxidation/rancidity if poorly stored, and possible pore congestion in very acne-prone users if used in heavy formulas. Because it is an oil, it is not suitable for water-based systems without an emulsifier.
