Salmon Oil

Salmon oil is derived from the tissues of salmon fish and contains a concentrated profile of long-chain omega-3 polyunsaturated fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These fatty acids are structural components that play a role in cell membrane integrity and skin barrier function.In skincare formulations, salmon oil functions as a skin conditioning agent. It is typically used at low concentrations (0 to 1%) where it helps to soften and moisturise the skin surface.

Salmon oil's primary mechanism in skincare is through its fatty acid content. These molecules integrate into skin cell membranes and the stratum corneum, the outermost layer of skin. This integration helps to restore lipid balance, reduce water loss, and support the skin's natural barrier function.The omega-3 fatty acids EPA and DHA are also precursors to signalling molecules called eicosanoids, which influence inflammation and immune response. However, the extent to which topical application of salmon oil triggers these processes in skin remains under research.

Salmon oil is typically incorporated into moisturisers, serums, and oils at low concentrations. It works well in combination with other emollients and humectants to enhance hydration. As with any oil-based ingredient, patch test first if you have sensitive or acne-prone skin, and consider the overall formulation to avoid over-occlusion.

Salmon oil is generally well-tolerated in topical skincare. However, some individuals report that high concentrations of oils may trigger or worsen fungal acne; formulations using salmon oil are typically kept below 1% to minimise this risk. Those with fish allergies should exercise caution.
