Linoleic acid is essential for healthy skin. It plays an extremely important role in building the protective layer that locks in and maintains moisture, while strengthening the barrier that keeps out irritants. Helping to protect the skin against chaps and cracks and dryness. It is therefore a must in any hand treatment, especially in Winter or when protecting hands from regular washing and hand sanitiser use. Many carrier oils contain Linoleic acid, but among those with the highest content are Evening Primrose oil, Sunflower oil, Grapeseed oil and Safflower oil. So whether you are making a scrub, serum or moisturiser, any of these oils would be a brilliant addition for nourishing your skin this season.
