Carrier oils, or base oils, are plant based oils used to dilute essential oils for topical use. They can also be used to make body scrubs, face masks and used for hydration and massage in general. There are soooo many to choose from, so how do you know which will work best for your needs? here ya go! This is a great place to start in learning about carrier oils. A wonderful resource for naming the main constituents, vitamins, thickness and useage for popular plant based carrier oils. My favorites are still coconut for body and rosehip, tamanu, grapeseed, jojoba and avocado for face!
