Walnut oil
Walnut oil is a lightweight yet nourishing plant oil extracted from walnuts, prized in skincare and haircare for its rich natural emollient properties and subtle nutty aroma. It is commonly found in UK moisturisers, facial oils, hair masks and lip treatments, where it helps soften and condition without leaving a heavy residue.
How it works in skincare
In cosmetics walnut oil functions as an emollient and skin-conditioning agent. Its natural fatty acid profile, particularly linoleic and linolenic acids, helps replenish the skin’s lipid barrier, reducing transepidermal water loss while imparting a smooth, non-greasy feel. It is often included in formulations for its ability to soften dry or rough skin and hair, improve suppleness, and deliver a healthy-looking glow in both leave-on and rinse-off products.

Where it comes from
Walnut oil is obtained by cold-pressing the kernels of the common walnut (Juglans regia), a deciduous tree native to regions from Europe to western Asia. The resulting golden oil is valued in British beauty formulations for its natural origin and nutrient content.
