Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Linseed oil, also known as flaxseed oil, has been used both traditionally and in modern times for skin care. Its application is scientifically supported, primarily due to its high content of alpha-linolenic acid (ALA), an omega-3 fatty acid with anti-inflammatory and skin barrier-supportive properties. Several studies have examined the impact of oral and topical linseed oil on skin health. Human trials have shown that oral supplementation with flaxseed oil can improve skin hydration, decrease skin sensitivity, and reduce roughness and scaling (e.g., Goyal et al., 2014, "Flax and flaxseed oil: an ancient medicine & modern functional food"). These improvements are attributed to the oil’s role in supporting the lipid barrier of the skin and reducing inflammation.

Topically, linseed oil is sometimes used as an emollient in natural skincare formulations, and it may aid in soothing dry or irritated skin. However, direct topical application may cause irritation in some individuals, and high-quality clinical evidence is limited compared to oral supplementation.

In summary, scientific evidence supports the use of linseed oil, especially orally, for improving general skin health, but the evidence is moderate rather than robust, and further research is warranted—particularly for topical use and in comparison to other oils.
