Juglans Regia (Persian Walnut) Seed Oil
What is Juglans Regia (Persian Walnut) Seed Oil?
Juglans Regia Seed Oil is derived from the seeds of the Juglans regia tree, commonly known as the Persian or English walnut, through cold-pressing to preserve its natural components. This plant-based oil is rich in polyunsaturated fatty acids, primarily linoleic acid, along with oleic acid and alpha-linolenic acid, and contains tocopherols as natural antioxidants. In cosmetics, it serves mainly as a skin conditioning agent, particularly an emollient, helping to form a protective barrier on the skin's surface. This allows it to lock in moisture, enhance skin suppleness, and improve texture without greasiness. It appears in formulations like creams, lotions, serums, and hair treatments, where it contributes to smoothness and shine by mimicking the skin's natural lipids and supporting barrier function. Its lightweight profile makes it suitable for both facial and body products.
