Citrus Grandis (Grapefruit) Seed Extract

What is Citrus Grandis (Grapefruit) Seed Extract?

Citrus Grandis (Grapefruit) Seed Extract comes from the seeds of the grapefruit plant, Citrus grandis, a large citrus tree originating from Southeast Asia. This natural derivative belongs to the category of plant extracts in cosmetics, valued for multifunctional properties. It functions as a preservative by leveraging natural compounds to deter microbial proliferation in formulations, promoting product integrity over time. As an astringent, it mildly constricts surface tissues for a firmer feel. In its role as a skin conditioning agent, it aids in preserving the skin's supple texture and hydration balance. The tonic aspect delivers a brisk, invigorating sensation, often refining the product's finish on application. Derived through extraction processes, it introduces bioactives like flavonoids, supporting stability in water-based cosmetics without synthetic additives.
