Citrullus Vulgaris (Watermelon) Seed Oil

What is Citrullus Vulgaris (Watermelon) Seed Oil?

Citrullus Vulgaris (Watermelon) Seed Oil comes from the seeds of the watermelon plant, Citrullus vulgaris, typically obtained via cold-pressing to preserve its natural components. This clear to pale yellow oil features a composition dominated by polyunsaturated and monounsaturated fatty acids, notably high levels of linoleic acid, along with oleic acid, palmitic acid, and trace stearic acid. It also includes tocopherols and plant sterols. In cosmetic formulations, it acts as an emollient and skin conditioning agent, softening the skin's surface by mimicking natural lipids, improving product texture for better application, and aiding barrier function to minimize water evaporation. Its light consistency absorbs quickly without residue, fitting into creams, serums, and oils for diverse product types across skin care routines.
