Essential oils must be handled carefully. Undiluted essential oils are very concentrated essences which may burn or sensitize the skin if applied pure and can cause major health and skin issues. Never apply essential oils directly to your skin unless they have been diluted with carrier oils, also known as fixed oils, which are vegetable or nut base oils extracted from kernels, seeds or pulp which contain only fatty acids, plus traces of vitamins and minerals. Carrier oils are used to dilute the essential oils to deliver them to your skin,without destroying the integrity of the oil so they can be safely applied topically by reducing skin sensitivity and also increase absorption through skin tissue . They act as the base for “carrying” the essential oil that is being mixed into it.
