Lemon oil has a sweet, fruity, light aroma that is genuinely reminiscent of the fresh peels. Lemon oil is often used in natural household cleaning solutions due to its cleansing, purifying, and invigorating properties. This oil is a key ingredient in many hair/skin care products and essential oil blends, but one should avoid applying Lemon oil to exposed skin before spending time outside due to photosensitivity.
