Eicosapentaenoic Acid
What is Eicosapentaenoic Acid?
Eicosapentaenoic acid, known as EPA, is a long-chain polyunsaturated omega-3 fatty acid primarily derived from marine sources like fish oils or produced via algae fermentation. In skincare formulations, it belongs to the category of lipid-based actives commonly found in moisturizers, serums, and anti-aging creams. As a skin conditioning agent, it integrates into the skin's natural lipid matrix, helping to restore barrier integrity and enhance suppleness. Functioning as an emollient, it reduces surface friction, promotes even distribution of other ingredients, and minimizes transepidermal water loss when combined with occlusive agents. Its unsaturated structure allows it to mimic epidermal fatty acids, supporting overall skin flexibility and resilience without greasiness. Topically, it contributes to product stability and sensory appeal, making it suitable for daily use in various textures.
