There are three paths that essential oils can enter into the body: • absorption through the surface of the skin • inhalation through the olfactory system • taken internally
The optimum way for the body to absorb the therapeutic qualities of essential oils is through a combination of inhalation and dermal absorption which can be achieved through massage and bathing.

How Dermal Absorption Works…
The skin is relatively permeable to fat soluble substances and relatively impermeable to water soluble substances.
Essential oil molecules are so minute that when they are applied to the skin; they are able to pass through the strateum corneum (the outer layer of the epidermis).
From here the oil molecule passes through dermis, into the capillaries and into the bloodstream. Absorption also occurs through the hair follicles and sweat ducts.
There are many factors that effect absorption of an oil molecule. Both rate of circulation and the warmth of the skin increase blood flow to the surface, therefore increasing the skin’s ability to absorb the oil. Circulation and warmth can be increased by massage. The larger the area of skin that is covered, the more essential oils will be absorbed. The permeability of the skin is also a factor.
Thinner skin ie: skin behind the ears and the inside of the wrists are very permeable. The palms of the hands and feet, armpits and scalp will more readily absorb oil molecules than the arms, legs, belly, back etc.
Oils are also easily absorbed through cuts, scraps and abrasions, burns, eczema etc. Eczema sufferers and those with skin conditions experience dramatic improvements when using oils.
Having clean skin is beneficial as the pores will be clean and free of dirt.
The optimum time to apply Aurora Alchemy oils is after a shower.
The other factor to consider when applying essential oils to the skin is the viscosity of the carrier oil in which the oil is diluted. Sweet Almond and Grapeseed Oil are less viscous and will penetrate the skin more easily than Olive or Avocado oils, which are thicker.
