Key Limes are a smaller and seedier variety of Lime with their own fresh, juicy scent. Key Limes are processed immediately after being picked in order to preserve the physical, chemical, and aromatic characteristics in this fresh essential oil. This fresh, bright citrus scent is just one reason you need this essential oil in your collection! Key Lime also has astringent and immune-supporting properties, as well as an energizing, stimulating smell you'll want to breathe in all day long.
