Arachidonic Acid
What is Arachidonic Acid?
Arachidonic acid is a polyunsaturated omega-6 essential fatty acid, naturally present in mammalian cell membranes and animal-derived fats like meat and eggs. Chemically, it features a 20-carbon chain with four double bonds, serving as a precursor to bioactive eicosanoids. In cosmetics, it falls under skin conditioning agents, primarily employed in creams, lotions, and serums at low concentrations. It functions by integrating into the skin's lipid barrier, enhancing flexibility and reducing surface roughness. As an emollient, it provides a smooth, slippy feel during application and supports moisture retention when combined with other lipids, helping maintain skin's supple texture without heavy occlusion.
