doTERRA has a variety of citrus oils, including Bergamot, Grapefruit, Lemon, Lime, Tangerine, and Wild Orange. All citrus oils come from the rind of the fruit. Citrus essential oils are also all produced using cold expression, also known as cold-pressing. These are also great oils to take internally or diffuse. Though you can use them topically, be sure to avoid sunlight for 12 hours after when applying the oil directly to your skin, whether Neat or diluted for sensitive skin.
