Cosmetic oils are natural or synthetic oils used in skincare and beauty products to enhance the appearance and health of the skin. They can be derived from various sources, including plants, seeds, and nuts, and are often rich in vitamins, fatty acids, and antioxidants. Common examples include jojoba oil, argan oil, and coconut oil, each offering unique benefits for hydration, nourishment, and protection. These oils can be used alone or blended into creams, serums, and lotions. They help to moisturize the skin, improve elasticity, and provide a protective barrier against environmental stressors. Additionally, cosmetic oils can be beneficial for various skin types, including dry, oily, and sensitive skin.
