What is Watermelon Seed Oil?
Watermelon seed oil is a natural oil taken from the tiny seeds inside watermelons. People get this oil by pressing the dried seeds. It's used for different things, like in cooking or in skin products.
Where Do Watermelons Come From?
Watermelons first grew almost 5,000 years ago in the Kalahari Desert in Africa. The wild plant, called the Kalahari Melon, still grows there today. People in that area have been pressing its seeds for oil for a very long time. Over many years, watermelons traveled north through Egypt. By the time of the ancient Romans, watermelons were grown and loved by many.
How Watermelon Seed Oil is Made
Just like their wild relatives, the seeds from the watermelons we eat today can be pressed to make oil. First, the seeds are taken out of the watermelon fruit. Then, they are left to dry in the sun. Once the seeds are completely dry, they are put into a special machine that presses them to squeeze out the oil.
