Watermelon Seed Oil
Watermelon Seed Oil, also known as Kalahari Oil or Ootanga Oil, is a lightweight, fast-absorbing oil cold-pressed from the seeds of the Citrullus lanatus fruit. This oil is pale yellow with a mild, nutty aroma and is rich in essential fatty acids—particularly linoleic acid (omega-6) and oleic acid (omega-9)—as well as antioxidants, phytosterols, and vitamins A, B, and E. Known for its nourishing, non-comedogenic, and balancing properties, Watermelon Seed Oil is widely used in skincare, haircare, baby care, and massage products. It is ideal for all skin types, especially oily, acne-prone, and sensitive skin due to its ability to dissolve sebum and unclog pores while maintaining hydration.
