Due to its composition rich in fatty acids and vitamins, camelina oil would present, among other things, numerous effects that help to maintain skin health. Let's examine them more closely in this article.
What are the benefits of camelina oil on the skin?
- Benefit No. 1: Camelina oil would hydrate the skin
- Benefit No. 2: Camelina oil could reduce skin inflammation
- Benefit No. 3: Camelina oil could potentially enhance wound healing
- Benefit No. 4: Camelina oil could slow down skin ageing
Benefit No. 1: Camelina oil would hydrate the skin.
Thecamelina oil could potentiallyhydrate the skin. A study conducted by Anna K. SHOVELLER and her colleagues evaluated the effects of 16 days of oral supplementation with camelina oil (8.2 g of oil/100 g of total food intake) on the quality of the coat and the skin barrier in 30 dogs. It was found that the softness of the skin, the shine, and the intensity of the colour increased compared to the initial situation.
This can be explained by the presence ofessential fatty acids in thecamelina oil, such as omega-3 (α-linolenic acid) at a higher rate than other vegetable oils (27.9%). Provided by diet, α-linolenic acid enables the synthesis of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Both influence the production of skin lipids such as ceramides, which are essential for maintaining the integrity of the skin barrier.
Overall, they allow the formation of a lipid barrier on the skin which helps to maintain skin hydration, making it more supple and less prone to dryness. Indeed, a previous study showed that a supplementation with fish oil, a rich source of EPA and DHA, improved the quality of the skin and coat of dogs after 8 weeks compared to the initial situation.
In topical application, camelina oil is also of interest. It contains phytosterols which have the ability to capture and retain moisture, making them effective moisturisers as demonstrated by numerous studies. The topical application of these compounds supports the hydrolipidic film present on the surface of the epidermis and helps to limit transepidermal water loss (TEWL). The moisturising properties of phytosterols are particularly important for individuals with dehydrated skin that is prone to tightness and discomfort.
However, it is important to note that there are no studies that have demonstrated a moisturising effect from the direct topical application of camelina oil.
Benefit No. 2: Camelina oil could reduce skin inflammation.
Camelina oil is rich in omega-3, also known for their anti-inflammatory and soothing properties, by increasing the synthesis of anti-inflammatory lipid mediators (resolvins and protectins) and competing with arachidonic acid, an omega-6 fatty acid that enables the production of pro-inflammatory mediators such as prostaglandin and leukotrienes. The inflammatory response will then be modulated.
These findings are supported by studies on the modulation of the inflammatory response by omega-3, particularly those by Karsten H. WEYLANDT and Jing X. KANG. Given that camelina oil is a significant source of polyunsaturated fatty acids (with a rate exceeding 55%), it is hypothesised that it could have the property of reducing skin inflammation, thereby helping to alleviate redness and soothe irritations.
However, the results on skin inflammation from the use of camelina oil are weak.
Benefit No. 3: Camelina oil could potentially enhance wound healing.
A study conducted by Raluca PAPACOCEA and her team in 2019 aimed to demonstrate the effect of the topical application of camelina oil on skin renewal and the healing process. This was examined through its impact on epithelialisation, a crucial component of wound healing measured by the expression of cytokeratin 5/14, involucrin, and transglutaminase, as well as on the restoration of the dermis through the acceleration of the fibroblast cell cycle and the amplification of collagen synthesis.
Camelina oil (0.2%) significantly stimulated the expression of cytokeratin 5/14, transglutaminase-1, and involucrin, suggesting a epidermal restoration. Furthermore, camelina oil is active in stimulating the S and G2/M phases of the fibroblast cell cycle, corresponding to DNA duplication and entry into mitosis, thereby enabling an increase in the rate of cell division and leading to rapid cellular regeneration.
They were also able to observe a boost in collagen synthesised by the fibroblasts treated with camelina oil, with an increase of 22% compared to the control after 48 hours of treatment. The camelina oil thus facilitated the acceleration of dermo-epidermal synthesis by stimulating the differentiation and renewal of keratinocytes, as well as the cellular division of fibroblasts and the synthesis of collagen.
The modulation of the inflammatory response, induced by the presence of omega-3 in camelina oil, as previously mentioned, also facilitates wound healing, particularly through collagen synthesis. Furthermore, omega-6, present in small quantities in camelina oil (18.7%), acts as a coagulant and aids in accelerating wound healing.
Benefit No. 4: Camelina oil could slow down skin ageing.
Although there is currently no scientific evidence demonstrating any effect of the direct application of camelina oil on skin ageing, camelina oil contains a significant concentration of tocopherols (70mg/100g), which are fat-soluble antioxidants. These act as a free radical scavenger (by donating an electron to stabilise the radicals), created by oxidative degradation, which can occur as a result of stress induced by oxygen, light or heat, for example. However, this action may contribute to slowing down skin ageing.
Furthermore, a study conducted by Natalia ROŞOIU and her colleagues demonstrated a strong correlation between the concentration of camelina oil (in solution with hexane, ranging from 1% to 10%) and the SPF (Sun Protection Factor). They observed that as the concentration of camelina oil increases, the recorded SPF also increases.

This outcome may suggest a potential effect of incorporating camelina oil into sunscreens to combat premature skin ageing associated with UV rays. However, the mechanisms that allow camelina oil to have this property are not yet known, and further studies are necessary to explore this aspect of its use.
However, camelina oil should in no way replace a sunscreen, with a minimum of SPF 30.
