Carrier oils are vegetable or nut oils used to dilute essential oils so they are safe to apply to the skin (or ingest, in some cases). The best carrier oil is cold-pressed and made from plants. Cold-pressed oils hold onto more of their beneficial properties since they are not subjected to heat. It’s best to choose unrefined oils that have no additives. Using a quality carrier oil, topically, without toxins, is just as important as being mindful of what you are putting into your body! Why? Our skin is our largest organ of our body and what goes onto your skin, goes into your into your body systems.
