What Is Borage Seed Oil/Hydrogenated Borage Seed Oil Esters?
Borage seed oil is derived from the seeds of the borage plant and is characterised by its high content of linoleic acid and gamma-linolenic acid (GLA), both essential fatty acids. In skincare formulations, it is often used in a hydrogenated form (hydrogenated borage seed oil esters) to improve stability and texture, making it easier to incorporate into creams, serums and other products.
The oil functions primarily as an emollient and skin protectant, meaning it helps to soften the skin and supports the structural integrity of the outer layers.
How It Works
The skin's outer layer (stratum corneum) relies on a precise mixture of lipids—including ceramides, cholesterol and fatty acids—to function as an effective barrier. Borage seed oil contains linoleic acid and GLA, which are incorporated into ceramides and other barrier lipids when applied topically or absorbed systemically.
By providing these building blocks, borage oil may help restore or maintain the skin's lipid composition, particularly in individuals with compromised barrier function or essential fatty acid deficiency. This supports the skin's ability to retain moisture and protect against environmental stressors.
Clinical Evidence & References
Research in animal models (guinea pigs with induced essential fatty acid deficiency) demonstrates that borage oil can increase the production of lamellar bodies—structures that store and release barrier lipids—and enhance the incorporation of linoleic acid and GLA into key ceramides. These findings suggest borage oil has a meaningful role in restoring barrier function under conditions of lipid deficiency.
However, evidence in human skin is more limited. Whilst the theoretical basis for borage oil's benefit is sound, the extent to which these effects translate to typical human skincare use remains an area requiring further investigation. It appears most beneficial for individuals with compromised or deficient barrier function rather than as a universal skincare ingredient.
How to Use
Borage seed oil or hydrogenated borage seed oil esters are typically incorporated into formulations by manufacturers rather than used as standalone products. If using a product containing this ingredient, apply as directed. For those with barrier concerns, consistent use over several weeks may be necessary to observe benefits. It pairs well with other barrier-supporting ingredients such as ceramides and niacinamide.
