Jojoba is a shrub native to the southwestern United States and northern Mexico. Its seeds contain a liquid wax that is often used in cosmetics and skincare products due to its moisturizing properties. This wax is similar to the natural oils produced by human skin, making it an effective ingredient for hydration. The jojoba oil extracted from the seeds is also used in hair care products, as it can help to nourish and strengthen hair. Additionally, jojoba is valued for its stability and long shelf life, making it a popular choice for various formulations in the beauty industry.
