Pure aromatherapy grade essential oils are highly concentrated and should not be used directly on the skin. When you start using essential oils, you should also become familiar with what we call carrier, vegetable, or base oils. You may only need to use 1 drop of essential oil and by itself, that will not go very far, but if you dilute it in a carrier or base oil, it will cover a large area.
Carrier oils are vegetable, nut or seed oils and many of them have their own therapeutic properties. Vegetable oils come from the seeds of plants that have oil-bearing seeds. There are many of this type of seed but only a few are produced commercially. Aromatherapy vegetable oils should be cold pressed. They are not produced in the same way that the oils on your supermarket shelves are produced. Use the following guidelines when diluting essential oils into carrier oils.

When you purchase essential oils, it is good to know that approximately:
20 drops = 1/5 tsp essential oil

60 drops -= 3/5 tsp essential etc.
