The oil: Grape seeds contain between 6 and 20 per cent oil. The oil is pale greeny yellow in colour and is very pure, high in polyunsaturates, and extremely light - it is almost as thin as water. This means that it is easily absorbed by the skin, which is very useful in aromatherapy because the essentials can penetrate very quickly.

Its uses: The seeds and leaves of grapes are rather astringent, so the oil can be used for conditions like acne.
