INCI: Cannabis sativa (Hemp) Seed OilExtraction Method: cold pressedAppearance: light green to dark green colorTexture: light to medium, quick absorbingAroma: earthy, nutty and grassy Hemp seed oil 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 has a long history of safe and effective use (Callaway et al, 2004). 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: Harvesting: Mature hemp plants are harvested, typically when the seeds have fully developed. Seed Cleaning: The harvested hemp seeds are cleaned to remove any impurities such as plant debris, dirt, or stones. Seed Crushing: The cleaned hemp seeds are then mechanically crushed or pressed to extract the oil. This process may involve various methods such as cold pressing, expeller pressing, or solvent extraction. 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. Expeller Pressing: Similar to cold pressing, expeller pressing also uses mechanical pressure but may involve slight heating. The heat generated during this process is typically low to avoid damaging the oil's delicate nutrients. Solvent Extraction: In this method, a solvent, such as hexane, is used to extract oil from the hemp seeds. The solvent helps dissolve the oil, and then it is separated from the solvent through evaporation. 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. Bottling and Storage: The filtered hemp seed oil is typically stored in dark, airtight containers to protect it from light and oxygen, which can cause oxidation and degradation of the oil. Proper storage helps maintain the oil's freshness and quality. It's important to note that hemp seed oil is different from cannabis oil, which is extracted from the flowers, leaves, and stalks of the hemp plant and contains cannabinoids like cannabidiol (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. 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. 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. Learn more: What is Linoleic Acid? Omega 6 Essential Fatty Acid for Dry Skin 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.

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. If you have specific concerns or sensitivities, it's advisable to consult with a dermatologist or skincare professional for personalized advice.
