COCOS NUCIFERA OIL.

Cocos Nucifera Oil primarily functions as an emollient, forming a protective occlusive layer on the skin due to its high concentration (90-95%) of saturated triglycerides, thereby significantly reducing transepidermal water loss and locking in moisture. It strengthens the skin barrier by promoting the expression of key structural proteins such as involucrin, filaggrin, and Aquaporin-3 (AQP3). Its anti-inflammatory efficacy stems from suppressing various pro-inflammatory cytokines, including TNF-α, IFN-γ, IL-6, IL-8, and IL-5, alongside downregulating iNOS and COX-2 pathways. As an antioxidant, it combats oxidative stress through phenolic acids like ferulic acid and p-coumaric acid, complemented by vitamin E. The oil's significant lauric acid content (approximately 50%) confers robust antibacterial and antimicrobial effects against pathogens like acne-causing bacteria and *Staphylococcus*. Furthermore, it supports wound healing by stimulating epithelial regeneration and collagen synthesis.
