Lemon oil is widely used in aromatherapy for its refreshing and uplifting scent, which helps reduce stress and improve mood. It is a common ingredient in cleaning products due to its natural antibacterial and antiseptic properties, making it effective for disinfecting surfaces. In skincare, lemon oil is added to formulations for its ability to brighten skin, reduce acne, and control excess oil. It is also used in hair care to promote scalp health and add shine to hair. Additionally, lemon oil serves as a flavoring agent in food and beverages, providing a fresh citrus taste. Its versatility extends to use in homemade remedies, such as natural insect repellents and air fresheners.
