There is often some confusion about using essential oils directly on the skin. While most oils are too potent to use neat (without diluting them in a carrier oil), there ARE some plants whose essential oils are gentle enough to apply to bare skin.
These are our two favorite ways of using essential oils on the body without a carrier:
2 drops of Lavender behind the ears and on the wrists before bed and you'll sleep like a baby.
1 drop of Tea Tree on a pimple before bed and it'll be gone by morning!
Disclaimer: it is always wise to test a tiny amount on your skin first, to make sure you are not hyper sensitive!
