Cherry Kernel Oil

Skin conditioning is one of the cosmetic functions the European Commission's ingredient database assigns to cherry kernel oil, and softening is what an emollient does. Together they leave skin feeling soft, smooth and silky after use – a description of how skin looks and feels rather than of anything happening beneath the surface, which is the line a cosmetic is allowed to stand on.

A fixed oil forms a light layer on the surface that helps skin hold on to its own moisture, which is what makes dry skin feel more comfortable with an oil on it. Cherry kernel oil is light enough to do that without a heavy, greasy film, so skin feels soft and looked-after for longer rather than tight and dry.

Cherry kernel oil is an emollient, the plain cosmetic word for something that works on the surface of the skin rather than underneath. It settles into the gaps between the flakes of partly shed skin that make a dry patch feel rough, so heels, elbows and hands feel smoother under your fingers within a minute of putting it on.

Work published in the Journal of Cosmetic Science measured oil-treated hair rather than describing it, recording lower combing force both wet and dry and higher gloss. Cherry kernel oil is light enough to do that on fine hair without weighing it down, so it leaves hair smoother and glossier – a fixed-oil property, not a claim about growth or strength.

Cherry kernel oil goes into the oil phase of serums, creams, lip balms and facial oils, and it is light enough to work in leave-on products a heavier oil would make greasy. It carries almost no colour or smell into a formula and suits normal and combination skin. Because it is high in unsaturated fats, including a conjugated one, pair it with an antioxidant.

Cherry kernel oil suits the lighter hair formats: pre-wash oils, conditioners, masks and leave-in serums, where its low weight means it rinses cleaner than a heavy oil and does not flatten fine hair. It brings slip and a smoother, glossier feel rather than any strengthening claim, and its faint, nutty smell sits under a fragrance.

For massage and body oils, cherry kernel oil gives the smooth, light glide that a long massage needs and a lotion cannot. It suits spa and body blends, bath oils and melt-and-pour bases, and its light body means it does not sit heavy on the skin afterwards. It is a fixed oil, not an aromatic one, so it carries a blend rather than scenting it.

Treat it as a light fixed oil. It joins the oil phase with your other oils before emulsification, needs no solubiliser in anhydrous work and a proper emulsifier for anything water-based. Its α-eleostearic acid is a conjugated fatty acid, which makes it more oxidation-prone than a plain oleic oil, so add a tocopherol antioxidant and store cool. One name on the INCI list.
