Butter

Butter in skincare typically refers to vegetable butters—solid or semi-solid fats extracted from plant sources such as shea, cocoa, or other seed oils. These are distinguished from liquid oils by their higher concentration of saturated fatty acids, which give them a firmer texture at room temperature.In formulations, butter functions as a skin conditioner and occlusive, meaning it forms a protective layer on the skin surface to reduce transepidermal water loss and help retain moisture. The fatty acid profile varies depending on the plant source, but most butters contain oleic and linoleic a…

Butters work primarily through their occlusive properties. When applied to skin, the fatty acids form a protective film that sits on the surface, reducing the amount of water that evaporates. This is especially useful in dry climates or for compromised barriers.Additionally, plant butters contain bioactive compounds—such as fatty acids, phytosterols, and antioxidants—that may interact with skin cells to support barrier function and reduce inflammation, though the exact mechanisms remain incompletely understood for most vegetable butters.

Butters are best used in formulations designed for dry or compromised skin, typically applied to damp skin to seal in hydration. Because of their occlusive nature, they work well in moisturisers, balms, and night treatments. For oily or acne-prone skin, they are generally best avoided or used sparingly, as they may feel heavy and potentially exacerbate congestion.

Butters are generally well-tolerated and considered safe for topical use. However, some individuals may experience congestion or breakouts, particularly if acne-prone; patch testing is advisable.
