why we use cannabis sativa (hemp) seed oil

A Time-Honoured Botanical: The Origins of Hemp Seed Oil

Hemp seed oil, extracted from the seeds of the Cannabis sativa plant, has been valued for centuries across cultures for its nourishing and therapeutic properties. Historically, hemp was cultivated as early as 8,000 BCE in regions like China, Mesopotamia, and Egypt, where it was used in traditional medicine, textiles, and skincare. Ancient civilizations recognised its moisturising, protective, and soothing effects. Hemp seed oil was often applied to heal wounds, calm irritation, and maintain skin suppleness.¹

Unlike other parts of the hemp plant, hemp seed oil is non-psychoactive and rich in essential fatty acids, vitamins, and antioxidants, making it a powerful emollient for modern skincare. Its unique blend of omega-6 and omega-3 fatty acids provides deep hydration while reinforcing the skin’s natural barrier, preventing moisture loss and promoting long-term skin health.

Skin Benefits of Hemp Seed Oil

Hemp seed oil is renowned for its exceptional ability to soothe, balance, and restore the skin. Its lightweight, non-comedogenic nature makes it suitable for all skin types, particularly acne-prone, sensitive, and compromised skin.

Rich in Linoleic Acid for Soothing & Oil Regulation

Hemp seed oil is naturally rich in linoleic acid, an omega-6 fatty acid essential for maintaining healthy skin function. Once applied, linoleic acid converts into arachidonic acid, which then influences prostaglandin E2, a key regulator of inflammation and skin repair.

Because of this, topical application helps reduce visible inflammation and supports the skin’s natural healing process. Additionally, research shows that acne-prone skin often lacks linoleic acid, which can lead to imbalanced oil production and increased breakouts.

By restoring linoleic acid levels, hemp seed oil helps regulate sebum, promoting a clearer, healthier-looking complexion. This makes it an excellent choice for those with sensitive, oily, or blemish-prone skin..^2,3

Antioxidant + Barrier-Strengthening Properties

In addition to essential fatty acids, hemp seed oil contains flavonoids, terpenes, and polyphenols, which provide strong antioxidant protection against environmental damage. As a result, these compounds help neutralise free radicals, which can accelerate signs of ageing and cause oxidative stress.⁴

Moreover, hemp seed oil helps reduce the visible effects of pollution, stress, and UV exposure, preventing premature skin damage. At the same time, its high concentration of alpha-linolenic acid (omega-3) and ceramides strengthens the skin’s lipid barrier.

Because of this, it effectively prevents trans-epidermal water loss (TEWL), keeping the skin hydrated, smooth, and resilient. Ultimately, hemp seed oil works as a powerful, multi-functional ingredient that helps defend, nourish, and restore the skin.
