Summary
This perfectly balanced oil has an impressive list of proven benefits to the consumer. The product's ideal balance as a cosmetic oil and as a fashionable ingredient meets the demands of the millennium's market.
What's old is new again. Hemp seed oil has been used for centuries for its medicinal and nutritional properties. Now the cosmetics industry is rediscovering this wonder oil. Not only is hemp seed oil new on the cosmetics scene, but it is a trendy product. Today's emphasis on environmentally-sound products calls for a multipurpose ingredient such as hemp seed oil. It is a perfectly balanced oil with an impressive list of proven benefits to the consumer. The product's ideal balance as a cosmetic oil and as a fashionable ingredient meets the demands of the millennium's market.
Across the globe, hemp products are renowned for their versatility. This popular material is used in clothing, accessories, home furnishings and even automobiles. Hemp is no longer confused as a "cannabis" product but is relished for its own reputation.
Four thousand years ago, China's Emperor Sheng Nung used hemp for rheumatism and constipation treatments. Buddha supposedly ate one hemp seed per day while fasting. Romans used hemp fibers in their ropes and sails. Gutenberg's Bible, the American Constitution and the Declaration of Independence were all printed on hemp paper. France's Nîmes weavers used hemp in manufacturing the first denim (De Nîmes). Since hemp made up the very first jeans, contemporary fashion has turned to hemp fiber. Hemp is not a trend that any industry can afford to miss. Armani, Calvin Klein and Ralph Lauren all use hemp in their fashion lines. "I believe that hemp is going to be the fiber of choice for the millennium," said Calvin Klein.
Botanical Aspects
This "choice" plant is actually a tall weed that grows worldwide. It has many applications, aside from its excellent use in hemp seed oil form. The plant itself grows rapidly (four times faster than trees). Hemp has been highlighted lately for its environmental soundness. A renewable biomass, hemp is grown without fertilizer or pesticides. In fact, the plant is a fertilizer itself. Therefore, without involving costly and potentially environmentally-damaging chemicals, hemp is a hardy, cost-efficient botanical that grows without damaging either the wallet or the environment.
It's no wonder that hemp is so widely used these days. Not only is the fiber used in paper, textiles and other products, but its hardiness makes it ideal for the building industry. Hemp is also edible and may even be found in modern food products; the nutritious oil helps reduce LDL cholesterol content.
Clearly, hemp has many beneficial uses but its full potential is realized in the form of hemp seed oil. The oil is edible, pleasing to the touch and perfectly balanced. cosmetic industry leaders recognize the desirability of high essential fatty acid contents. Hemp seed oil contains one of the highest levels of essential fatty acids: 76%.
Essential Fatty Acids and the Skin
EFAs (essential fatty acids) are very important in cell membranes. The more saturated the fatty acid, the less fluid the membrane. PUFA (poly-unsaturated fatty acids) are incorporated in the 2 position of the phospholipids constituting cell membrane. Afluid membrane is crucial for proper cell function. EFAs and their importance to the skin have been the subject of many studies.
Horrobin (J. Am. Acad. Dermatol. 1989 20 1045-1053) and later Wright (Br. J. Dermatol. 1991 125 503-515) have reviewed Essential Fatty Acid Deficiency (EFAD) consequences on the skin. They found that EFAD can lead to:
Scaly epidermis;
Hypertrophy of the sebaceous glands and hyperkeratosis of sebaceous ducts;
Weakened cutaneous capillaries;
Increased transepidermal water loss (TEWL) and
Thin, discolored hair, or hair loss
Furthermore, EFAD plays a role in atopic eczema, acne and psoriasis.
Nutgeren, et. al. (Biochim. Biophis. Acta. 1985 834 429-436) proved that EFAs are absolutely necessary for maintaining the proper skin condition of water barrier in the skin. Direct topical application on linoleic acid (LA) to the skin restores the barrier in animals with EFAD. It as been shown that radiolabeled LA is incorporated mostly in an acyl ceramide (ceramide 1) in which LA was esterified to the end position of a very long chain unsaturated omega fatty acid. In EFAD, LA is replaced by oleic acid in the ceramide, which is unable to form a normal water barrier.
PUFA supplementation influences the rate of biosynthesis of EFA derivatives as it seems to depend on the size of the precursors pool. Supplementing gamma linoleic acid (GLA) results in an increase of the less inflammatory PGE2. Similarly long chain omega-3 acids supplementation induces a marked reduction in LA and arachidonic acid (AA) in membrane lipids and also result in local generation of the less inflammatory PGE3.
Also, dihomo gamma linoleic acid (DGLA) is converted in the skin to PGE1, which is known to raise the levels of cAMP which in turn inhibits PLA2 (what's PLA2) and so exerts anti-inflammatory effects by keeping AA locked into the phospholipidic membrane. Thus access of free AA to cyclo-oxygenase is denied and pro-inflammatory PG2 level is reduced. This implies the necessity of a well balanced mix of PUFA in the diet and in topical application.
The Right Prostaglandins are Extremely Important
Larregue (Prostaglandines et thromboxanes Masson 1997) reviewed the importance of prostaglandin (PG) in skin. PGs are not stored but are synthesized on request after being stimulated. PG2 are synthesized from AA present in cell membranes.
PG2 is a powerful vasodilator and contributes to the characteristic edema related to inflammation. It must be noted that PG1 and PG3 are less pro-inflammatory. PGs are also immune modulators: PGE2 is a powerful inhibitor of cytotoxic T cells activity. In situ PG production happens simultaneously with UV erythema. Therefore omega-3 PUFA, by helping prevent PG2, has a photo-protective effect on skin.
