I would think in general oil would clog more than it would clear your skin up but i am def no expert since i dont use it....i found this on grapeseed oil though
In all products grape seed oil is a preferred cosmetic ingredient for damaged and stressed tissues, possessing regenerative and restructuring qualities which allow a better control of skin moisturization. It can help skin retain the normal structure of epithelium cells and nerve cells via supporting the cell membranes.[citation needed] It is noted to be especially effective for repair of the skin around the eyes. Used as an all-over skin moisturizer, grape seed oil is known to reduce the look of stretch marks. A light, thin oil, grape seed oil leaves a glossy film over the skin when used as a carrier oil for essential oils in aromatherapy. It contains more linoleic acid than many other carrier oils. Grape seed oil is also usable as a lubricant for shaving your face.
and this on jojoba:
Unlike common vegetable oils, jojoba oil is chemically very similar to human sebum. Most jojoba oil is consumed as an ingredient in cosmetics and personal care products, especially skin care and hair care. Jojoba derivatives, including jojoba esters, isopropyl jojobate and jojoba alcohol, are particularly widely used in this context
