As a collective society we are trending towards utilizing more natural, sustainable, and organic ingredients in our everyday lives – and that includes our skin care. As this trend continues to evolve you’ll see cosmetic companies prove to be more involved with the movement of educating their clientele on the harms of chemical ingredients on the skin and the benefits of using natural alternatives. In turn, a multitude of personal care product brands have begun incorporationg hemp seed oil into their formulations.
Today, we’re going to breakdown hemp seed oil in cosmetics and review the 3 elements of hemp that make it so effective in such a vast array of personal care products.
Hemp seed oil is a nutrient-rich oil pressed from hemp (Cannabis Sativa) seeds which contains approximately 76% Essential Fatty Acids (EFA):
◊ 25% Omega3
◊ 58% Omega6
◊ 1.9 % to 5% Gamma-Linolenic Acid (GLA)
Cold pressed, unrefined hemp oil is dark to very light green in color with a nutty flavor and earthy smell. It belongs to the most valuable vegetable oils as it contains important substances such as α-and γ-linolenic fatty acids (mentioned above), vitamins, minerals and phytosterols, which, due to modern way of life, are not sufficiently supplied to our body in their natural form.
Hemp seed oil in cosmetics works as a moisturizing and penetrating oil that can be used directly on the skin or as a valuable addition to other skin care products.
1) Hemp seed oil contains 50%-60% Linoleic Acid and is the only high EFA oil that also contains GLA.
◊ Only the EFA Linoleic Acid and its metabolite Gamma-Linolenic Acid have clinically proven biochemical and therapeutic effects on the skin. (Solely generic use of unsaturated or Essential Fatty Acids has limited benefits to the skin).
2) Hemp seed protein contains all 20 Amino Acids – including the 9 Essential Amino Acids – and features a high content of the two sulfur-containing Amino Acids Methionine and Cystine, which are usually even further under-represented in vegetable proteins. (Whole hemp seed contains about 23% protein).
◊ Amino acids, the building blocks of proteins, have become an increasingly important class of cosmetic raw materials from a standpoint of both performance and consumer appeal. The proteins used in personal care products have, traditionally, been derived from collagen or keratin. Recently, however, there has been an increasing demand for proteins that are vegetable derived.
3) Hemp seed oil’s superior EFA profile naturally resembles the skin’s lipids which allows it to replenish the skin with its essential components increasing moisture retention.
◊ The skin’s optimal state is characterized by a balanced ratio of skin lipids to skin moisture. The health of skin depends largely on moisture retention provided by the stratum corneum, the outer layer of the epidermis. Damage caused by the sun, dry air, harsh soaps, and the slowdown of cell metabolism from aging change the lipid composition of the epidermis and reduce the skin’s moisture retention capabilities, no longer enabling it to protect the body from excessive water loss.
◊ Lipids are composed of fat-like substances including sterols, free fatty acids and ceramides. Ceramides are a class of substances that contain different polyunsaturated fatty acids that make up about 18% of the upper layers of the stratum corneum.
◊ Ceramide 1, found in the Omega-6 Linoleic Acid, is of critical importance to skin’s moisture control.
Hemp seed oil is then a top ingredient for today’s performance skin care market because its EFA profile closely resembles the skin’s lipids, it contains all 20 Amino Acids, and it contains the proven elements of EFA Linoleic Acid and its metabolite Gamma-Linolenic Acid.
