The oil contains naturally occurring compounds called carbazole alkaloids, which give it antimicrobial and antioxidant properties. In skincare formulations, it primarily functions as a preservative to help extend shelf life and maintain product stability.Beyond preservation, the oil has been studied for potential wound-healing benefits, drawing on its long history in folk remedies. The traditional use prompted scientific investigation into how its active compounds might s…

The carbazole alkaloids present in Murraya koenigii leaf oil exert their effects through multiple pathways. Their antimicrobial action disrupts the growth of bacteria and other microorganisms, which is why the ingredient functions as a preservative. Simultaneously, these compounds work as antioxidants, neutralising reactive oxygen species that can damage skin cells and accelerate visible ageing.In wound-healing contexts, research suggests these alkaloids may enhance collagen deposition and accelerate epithelialisation—the process by which new skin cells form to close a wound.
