As has already been noted, CBD on its own is a real boon to our bodies. It has been used for centuries as a nutritional supplement, among other things. Essential oils, too, have been used medicinally for centuries. But, essential oils themselves are pretty strong and if you have sensitive skin, direct application could cause a reaction. Plus, diluting the essential oil in a carrier oil may increase the therapeutic benefits for two reasons.
First, essential oils are extremely volatile and tend to evaporate quickly. So, before it is even absorbed into the skin, a good chunk of it evaporates into the air. Now, given the expense of essential oils, to have most of it evaporate before the benefits can be achieved seems counterproductive. Enter the fatty carrier oil, which doesn’t evaporate at all. It will contain the essential oil and as your skin absorbs it, the benefits of all the oils are absorbed with it.
Second, by settling an essential oil into a carrier oil, such as fractionated coconut oil, sweet almond oil, avocado oil or other such oils, allows you to spread the essential oil over a more of your body, helping absorb it into a larger area.
