Hemp has been used in many ways with many different applications for over 10.000 years (1) . However, due to being commonly mistaken with the drug-type of Cannabis sativa (marijuana) (2), hemp, or industrial hemp, was neglected for years and still now a days is misjudged by the majority of people.
Nevertheless, over the last 20 years, a growing interest have turned eyes back to this plant. This time, because of the promising potential of its seeds, and the oil extracted from them, which are believed to be a great component to be added to cosmetics and or to human and animals diet. All of it supported by early findings by comprehensive reviews in Food Science and Food Safety (2) of excellent nutritional and therapeutical values found in hemp.
Scientists have observed that the hempseed contains the highest proportion of omega‐6 and omega‐3 polyunsaturated fatty acids (PUFAs) (2, 3) and may also be a source of natural antioxidants, which are well-known for promoting health and disease prevention as highlighted by this study in the Department of Nutrition and Food Science (4).
Additionally, studies in Australia (5) and Canada (6) have also found that the cannabinoids found in hemp, revealed anti-inflammatory, anti-ageing, anti-malignancy and anti-microbial properties without having any psychoactive effects, as it presents only traces (<0.3% w/w) of tetrahydrocannabinol (THC), renowned by its psychoactive and medicinal characteristics, found mainly in the drug-type of Cannabis sativa (2).
With all these recent findings, studies and scientists are confirming that adding hemp seeds or hemp seed oil to your diet or to your daily care is one of the best things you can do for your body.
So, in this blog post, we summarised for you what the scientific community have found about hemp so far with a list of 9 benefits of hempseed or hempseed oil on the skin and by the end of this article you will find out that hempseed can be indeed a daily healthy ally for your skin, hair and health in general.
1- It’s great for dry, sensitive and irritated skin
A study published in the Journal of Dermatological Treatment (3) have shown that dietary hempseed oil can be useful in treating symptoms of atopic dermatitis. According to these studies, when added hempseed oil to the diet, the trans-epidermal water loss values decreases, and both skin dryness and itchiness quality improves, consequently reducing the usage of dermal medication.
Scientist believe that this clinical improvement is due to the significant changes in fatty acid profiles in the human plasma caused by the balanced and abundant supply of PUFAs found in the hempseed oil.
2- Regulates Oily skin
Hempseed oil presents sebum-regulating effects (7), which for oily skins, works reducing sebum secretion and erythema on human face. According to a study published in 2015 in the Pakistan Journal of Pharmaceutical Sciences (8), hempseed oil has significant efficacy and has good tolerability for reduction of skin sebum and erythema content.
3- Prevents acne
As also pointed by the previous study and supported by other studies on Pharmacognosy (9) and Medical Practice (10), because of hemps anti-microbial property, its oil strengths the skin making it better to resist bacterial, viral and fungal infections. For this reason, it can be a good choice for treatment against acne, even in its more severe forms.
4- helps in rash treatment
Yet, according to the last study mentioned in the previous topic - Hemp seed oil as a dietary supplement in Medical practice (10) - Hemp seed oil is useful for treatment of eczema and host of other skin diseases like dermatitis, seborrheic dermatitis/cradle cap, varicose eczema, psoriasis, lichen planus topic dermatitis and other skin diseases, for instance lupus, rosacea and even burns.
5- prevents signs of ageing
Studies have shown that some great fighters against this ageing process, are the polyunsaturated fatty acids (omega-6 and omega-3), which are essential to skin health and found in a perfect proportion in hempseed oil (the closest to the human skin composition and body). These essential fatty acids (EFAs) are proven to play a preventive role in skin ageing and a healthy moisture balance for the skin. Additionally, can be used as topical (applying direct to the skin) or oral taking it daily simply adding it to your diet (11).
6- cleanses the skin
Because of its anti-microbial property, antioxidants and the essential fatty acids (EFAs), hempseed oil can be great for also cleaning your skin by just apply a few drops onto and massaging it with your finger tips. Besides removing bacterias, it offers great skin protection by strengthening the ‘natural barrier’ and the natural defence mechanisms.
7- Works as moisturiser
As already mentioned before, hempseed is rich in essential fatty acids (EFAs). These EFAs act trapping the moisture on the skin and are found in hempseed oil in an incredible matching proportion to our skin and body. The role of fatty acids in skin health is prominent. Hence, it’s crucial to supply EFAs to our body either applying hempseed oil direct to your skin or including it on your diet (11).
8. calms the skin after shaving
Scientists in Romania (14) have found that hemp has anti-inflammatory, anti-microbial properties and unsaturated fatty acids, make of it a great after-shaving product for your skin. The only thing you need to do is to apply a small amount of the hempseed oil direct to the skin recently shaved. It accelerates the healing of skin wounds, regenerates the skin and calms the burnt caused by the razor as mentioned above, helps to keep the skin moist and soft.
9- it can ben incorporated to many other cosmetics and have an even wider range of use and benefits
If incorporated to cosmetics such as shampoo, hair conditioner, styling gel, skin cream or lotion, the hempseed oil can exhibits great conditioning properties into both skin and hair. The essential fatty acids and its rich elements restore hair strength enabling a biological maintenance and repair, besides providing an unexpectedly superior level of smoothing, softening to the hair and elasticity and moisturisation to the skin (12).
Additionally, a study published in bioresources.com (13) in Australia have shown that because of its antimicrobial activity, hemp can work pretty well if incorporated into toothpaste, mouth-wash, toilet-bars, antiseptic ointment and foot powders.
Even though being commonly mistaken with he drug-type of Cannabis sativa (marijuana) and for that reason, being neglected for so many years. There is a growing interest not only by the science community but also by the population in general, on Hemp. The reason for that is because of the promising potential of its seeds, and the oil extracted from them.
Its highest proportion of omega‐6 and omega‐3 polyunsaturated fatty acids (PUFAs) and its closest rate to the human skin composition and body, ever found in a plant, makes of it the player that was missing on your daily routine for preventing many skin problems, from the preventing ageing signs to reliving pain caused by some still misunderstood skin diseases.
As pointed by this blog article, if you are still unsure of the benefits this plant can bring to your life, one thing we and scientists from all over the world can agree on: a daily dose of hemp oil (not the drug type) will only benefit you either on a short or a long term.
