Absorption is a route by which substances can enter the body through the skin. Along with inhalation, ingestion and injection, dermal absorption is a route of exposure for toxic substances and route of administration for medication. Absorption of substances through the skin depends on a number of factors, the most important of which are concentration, duration of contact, solubility, physical condition of the skin and part of the body exposed. Certain substances called carriers can be used to greatly increase the amount of another substances that is able to penetrate the skin. Dimethyl sulfoxide (DMSO) is a carrier that is frequently used to transport medication through the skin. This allows treatment to be localized, unlike with ingestion.

Absorption Base
An absorption base is used to enable beneficial herbs and ingredients, collagen and vitamins to be absorbed into the surface of the skin. An absorption base allows the active ingredients of a product to penetrate into the skin. Essential oils are an absorption base that can be a mixture of alcohols, acids, oxides, lanolin, esters, sulfur compounds, ketones, ethers, ketones or aldehydes. A good absorption base is fatty acids vitamins and it also moisturizes the skin.OTHER GOOD INFO HERE

Essential Oils Penetrate
The penetrating characteristic of essential oils greatly enhances their ability to be effective. Essential oils will penetrate into the body when applied to the skin. Placed on the foot they will be distributed to every cell in the body in 21 minutes. They will even penetrate a finger or toe nail to treat fungus underneath.
Essential oils last 20 minutes in the body
Oils are a precursor to set up stage for action and a catalyst to do the work (the bloodstream). Oils go where the need is present and are activated in that area. Testing on thyroid, heart and pancreas showed that the oils reached these organs in 3 seconds. When layered, one oil applied over another, it is faster. The body absorbs the oils fasted by breathing and second fastest by applying to the feet or ears. Essential Oils also cross the blood brain barrier. They piggy-back the energy waves to get into the cells.

Compared to other body structures, the skin is unique in being perpetually exposed to the environment.
The rate of dermal absorption of a substance is proportional to both the concentration of the substance and the surface area over which it is applied. The wider the contact area and the more concentrated the substance, the greater will be the absorption.
The thickness of the skin, especially the stratum corneum, also determines the degree to which substances are absorbed. there is much more:

Some of the aromatic 'essential' oils used in aromatherapy do have well-documented therapeutic actions. However, many of the oils for which aromatherapists claim physiological medical activity, in fact possess no recorded historical medicinal actions
Most aromatherapists claim explicit physical effects after massaging with oils, for example: "Fennel is diuretic," "Geranium regulates the hormonal system," "Grapefruit is good for cellulite." However, none of these effects have been proven when these oils are applied to the skin during massage.
One example of the misleading hype is found with Fennel oil. It is well known for producing an increase in urine output when it is taken as a medicine. However, when the volume of fennel oil used in the average massage is applied, it is doubtful that enough can be absorbed through the skin to elicit any such diuretic action. If very large amounts are used on the skin, or it is occluded - such as with compresses - or the essential oil is used in hot humid environments, then I am prepared to accept some oil may get into the subcutaneous tissues.-PLEASE READ THIS ENTIRE ARTICLE VERY INTERSTING:

Skin absorption studies at the University of Michigan demonstrated that jojoba is quickly absorbed into the skin, which is apparently via the transappendegeal mechanism and occurs through the pores and hair follicles – but because it is so rapidly absorbed, the pores and hair follicles remain open and thus maintain their proper functioning ability.

YOUR SKIN ABSORBS UP TO 60% OF WHATEVER IS APPLIED - INCLUDING TOXIN

Human skin will not absorb most common waters because of incorrect application and an incompatible pH balance.

The skin can absorb chemicals, not just nicotine from patches, but harmful toxins and carcinogens, and yet these can be found in many personal care products.

For example, mineral oil is never used in aromatherapy not only because it is not a natural product but because itmay prevent the absorption of essential oil into the skin. Aromatherapy carrier oils on the other hand function specifically to help the skin absorb essential oil.

Dear Dr. Gott: Does the skin absorb all the bath oils and lip creams that we apply? I use so much lotion and cocoa butter on my hands and feet in the winter that I am concerned about the cholesterol and triglyceride fats that may be entering my body.
Dear Reader: Under ordinary circumstances, the substances in topical products are not absorbed through the skin into the body, although they are absorbed into the skin itself.
