Jojoba seeds are the small, oval-shaped seeds of the Simmondsia chinensis plant, a desert shrub. These brown seeds are highly valued not for direct consumption, but for the unique liquid wax they contain, commonly known as jojoba oil. This "oil" is chemically similar to human skin's natural sebum, making it an exceptionally popular and effective ingredient in cosmetics, skincare, and hair care products. Jojoba seeds are typically harvested when they naturally drop from the plant and are then cold-pressed to extract their precious, stable liquid wax.
