One of the most beneficial essential oils for skin care is geranium oil. This oil contains nutrients that help hydrate the skin, which is imperative for the regenerative process of skin cells. This oil is generally considered safe for sensitive skin, as well for those with frequent breakouts.

Oils applied to the body bring the wearer the energies of the oil -- an Energy Oil will give you a much-needed boost, a Courage Oil will give you strength in the face of adversity.
