Hemp Seed Oil

What is hemp seed oil?

Hemp  seed oil (Cannabis sativa) is obtained by pressing hemp seeds from the hemp plant and extracting the oil. 

Cold-pressed, unrefined hemp seed oil is a vibrant green color, with an earthy, nutty flavor. 

Hemp seed oil should not be confused with hash oil or cannabis oil, which also comes from the cannabis plant, and contain psychoactive cannabinoids THC and/or CBD.

Hemp seed oil does not contain significant amounts of cannabinoids and is primarily valued for its nutritional properties, including essential fatty acids and vitamins.

Hemp seed oil has a long history of safe and effective use (Callaway et al, 2004).

Hemp Seed Oil

How is hemp seed oil made?

Hemp seed oil, also known as hemp oil or hempseed oil, is derived from the seeds of the hemp plant (Cannabis sativa).

Here's a general overview of the process involved in making hemp seed oil:

  1. Harvesting: Mature hemp plants are harvested, typically when the seeds have fully developed.

  2. Seed Cleaning: The harvested hemp seeds are cleaned to remove any impurities such as plant debris, dirt, or stones.

  3. Seed Crushing: The cleaned hemp seeds are then mechanically crushed or pressed to extract the oil. 

    • Cold Pressing: This method involves using a mechanical press to apply pressure to the hemp seeds, extracting the oil without the use of heat. Cold pressing helps preserve the nutritional profile of the oil.

  4. Filtration: After the oil is extracted, it undergoes a filtration process to remove any remaining solids or impurities. This step ensures a cleaner and clearer oil.

What does hemp seed oil smell like?

The smell of hemp seed oil depends on how it is processed and refined.

Hemp seed oil has a distinct aroma that is often described as a combination of earthy, nutty, and grassy scents. Some people also detect a slightly sweet or herbal undertone in the smell. The scent can vary slightly depending on the quality and processing of the oil, but overall, it tends to have a characteristic and recognizable aroma.

Unrefined hemp seed oil has the strongest aroma. 

Refined hemp seed oil has the mildest aroma.

What color is hemp seed oil?

The color of hemp seed oil depends on how it is processed and refined.

Cold-pressed, unrefined hemp seed oil is a rich vibrant green to dark green liquid.

In contrast, refined hemp seed oil has a pale yellow to golden yellow liquid.

What does hemp seed oil feel like?

Hemp seed oil has a lightweight consistency and is easily absorbed into the skin, making it suitable for various skin types, including oily and acne-prone skin.

Unrefined hemp seed oil is easily absorbed in to the skin.

Refined hemp seed oil feels a bit heavier, and absorbs into skin at average speed, leaving a slight oil feeling left on skin.

Hemp Seed Oil

What is composition of hemp seed oil?

Cold-pressed, unrefined hemp seed oil is packed with essential nutrients, including fatty acids, vitamins and antioxidants (Leizer et al, 2000).

Hemp seed oil is composed of fatty acids including:

    • 56% linoleic acid (n-6)
    • 16% alpha-linolenic acid (n-3)
    • 11% oleic acid (n-9)
    • 5% gamma-linolenic acid

Hemp seed oil contains 56% linoleic acid, the major essential n-6 fatty acid found naturally in our skin barrier. Linoleic acid is a precursor for ceramides (Breiden et al, 2014), which are bioactive lipids that play a role in keeping our skin barrier firm, smooth and healthy.

Hemp seed oil contains 16% alpha-linolenic acid, an essential omega 3 fatty acid that calms redness and irritation (McCusker et al, 2010).

Hemp seed oil contains 11% oleic acid; an omega-9 fatty acid found naturally in the protective outer layer of the skin.

Hemp seed oil contains 5% gamma-linolenic acid, a unique n-6 fatty acid with potent anti-inflammatory activity (Kapoor et al, 2006).

Hemp seed oil is also rich in vitamin E, and phytosterols including β-sitosterol, phytol and campesterol.

Because hemp seed oil is derived from the seeds of hemp plants, rather than the stalks and leaves, it contains only trace amounts of cannabinoids such as THC and CBD.

What are the 5 benefits of hemp seed oil?

Hemp seed oil has many benefits for dry skin.

1. Hemp seed oil nourishes dry skin

Cold-pressed, unrefined hemp seed oil is a vibrant green oil packed with essential nutrients, including fatty acids, vitamins, and antioxidants (Leizer et al., 2000).

It contains linoleic acid (n-6), alpha-linolenic acid (n-3), and vitamin E, nutrients essential for healthy skin that must be supplied through diet, supplements, or skincare.

Topical application can help strengthen your skin barrier and improve the appearance of dry, dull skin.

2. Hemp seed oil softens and conditions dry skin

Hemp seed oil is rich in fatty acids, linoleic (n-6), alpha-linolenic (n-3), and oleic (n-9), that act as emollients. Emollients:

  • Soften and smooth the skin
  • Reduce flaking and roughness
  • Support the skin barrier by filling in gaps between cells

By replenishing lipids on the skin’s surface, hemp seed oil restores suppleness, elasticity, and a healthier appearance (Brown et al., 2005).

3. Hemp seed oil strengthens your skin barrier

Hemp seed oil contains about 56% linoleic acid, a key n-6 fatty acid naturally present in the skin barrier. Linoleic acid is a precursor to ceramides (Breiden et al., 2014), bioactive lipids that help keep the skin firm, smooth, and healthy.

Hemp seed oil also provides 11% oleic acid, an omega-9 fatty acid found in the skin’s protective outer layer. Oleic acid is quickly absorbed, softening dry skin and supporting barrier function.

4. Hemp seed oil calms redness and irritation

Hemp seed oil is naturally rich in omega-3 (alpha-linolenic acid) and gamma-linolenic acid, two fatty acids with potent anti-inflammatory properties. These nutrients help reduce redness, soothe irritation, and support sensitive or reactive skin (McCusker et al., 2010; Kapoor et al., 2006).

By helping to regulate inflammatory processes in the skin, hemp seed oil can calm flare-ups caused by dryness, environmental stressors, or minor skin conditions. Regular use can leave your skin feeling calmer, more comfortable, and less reactive, while also helping to maintain a balanced, healthy appearance.

5. Hemp seed oil protects your skin

Hemp seed oil is rich in antioxidants, including vitamin E and phytosterols such as β-sitosterol, phytol, and campesterol (Chen et al., 2010; Chen et al., 2012; Porto et al., 2014).

 These compounds neutralize free radicals, unstable molecules generated by UV radiation, pollution, and aging, which can damage skin cells and accelerate skin aging (Masaki et al., 2010).

By protecting against oxidative stress, hemp seed oil helps maintain healthier, more resilient skin.

Hemp Seed Oil Benefits for Skin

Does hemp seed clog pores?

Hemp seed oil is generally considered non-comedogenic, which means it has a low likelihood of clogging pores. It has a lightweight consistency and is easily absorbed into the skin, making it suitable for various skin types, including oily and acne-prone skin.

Hemp seed oil has a unique fatty acid profile, rich in omega-3 and omega-6 fatty acids, as well as other beneficial compounds such as vitamins and antioxidants. These properties make it nourishing for the skin without causing excessive oiliness or pore congestion.

However, it's important to note that individual reactions to skincare products can vary. While hemp seed oil is unlikely to clog pores for most people, it's always recommended to patch test new products on a small area of your skin before applying them to larger areas of your face or body.
