What essential oils can be used directly on the skin

Undiluted essential oils should never be used on the skin. Always dilute them with a base oil or emulsifier. Please seek the advice of a natural health practitioner before using an essential oil you are unsure about. And never touch the eyes or mucous membranes such as the nose. Essential oils such as Lavender and Tea tree are generally accepted to be safe to use topically, however caution should always be exercised when using any essential oil, common or otherwise.
