Cape Chestnut Seed Oil
Cape Chestnut Seed Oil, also known as Yangu Oil, is a cold-pressed oil extracted from the seeds of the Cape Chestnut tree (Calodendrum capense), native to Southern Africa. It is prized in skincare for its non-comedogenic, UV-protective, and antioxidant-rich profile. With a light to medium texture and a mild, nutty aroma, the oil absorbs easily into the skin without clogging pores.
Rich in essential fatty acids, especially linoleic and oleic acid, as well as natural sun-protective compounds and polyphenols, Cape Chestnut Seed Oil is especially beneficial for sensitive, dry, or UV-exposed skin. It is commonly used in cosmetic formulations, hair care products, and aromatherapeutic applications for its protective and nourishing properties.
