What is a carrier oil?
A carrier oil refers to a vegetable oil, wax, fat, or other oil that an essential oil is mixed with. The carrier oil (or base oil) "carries" the essential oil and dilutes it so it can effectively be spread over a larger area.
Coconut Oil Is A Great Carrier Oil
Applying essential oils directly on your body without any kind of dilution is often referred to as applying the oil "neat."
Since essential oils are so potent and powerful, and because some oils may irritate your skin, you can reduce the chance of experiencing any irritation by diluting your oil with a carrier oil - such as fractionated coconut oil, almond oil, olive oil, jojoba oil, etc.
Because essential oils are so potent, using more is not necessarily better. To achieve optimum results, 1-3 drops of oil per application are usually enough.
The bottoms of your feet are one of the most common areas to apply essential oils because you have larger pores there, so the oils absorb more quickly. Some other areas that absorb oils quickly include behind your ears and on your wrists.

When massaging essential oils into a large area of your body, it is recommended to dilute your oils by 15% to 30% with a carrier oil.
For Skin Sensitivities, It's Best To Dilute Essential Oil With A Carrier Oil
When applying essential oils to infants and small children, it's best to dilute the oil with a carrier oil. Use 1 drop of essential oil to 1 tablespoon of carrier oil for infants, 1 drop to 1 teaspoon for children, and 3-6 drops of essential oil to 1 teaspoon of fractionated coconut oil (or other carrier oil) for adults.
Why The Quality Of Your Essential Oil Matters
Because essential oils are fat-soluble (which means they dissolve in fats but not water - remember oil + water don't mix), when they are applied directly to the skin ("neat"), their chemical compounds are readily absorbed and enter the bloodstream. This is only one reason why the QUALITY of your essential oils is important.
Many high-quality oils are safe to use "neat," and one of the most universally accepted locations for "neat" application of oils is the bottoms of feet.
Rubbing Essential Oil on Bottoms of Feet
Carrier oils are used not only for dilution but also to prevent evaporation. Using a carrier oil PRIOR to applying an essential oil will slow down the absorption process, but will not prevent absorption, and therefore slowing down the therapeutic onset.
Applying a carrier oil AFTER essential oil application enhances the therapeutic onset of the oil.
Either way, the carrier oil will help prevent the potential rapid evaporation of the essential oil.

Is It Best To Use Pure Essential Oil Or Diluted Oil?
Here is an interesting video that discusses whether it's better to use pure essential oil (applied "neat") or if you might want to dilute your oil first:
This video brings up some important things for you to consider when using essential oils:
- Evaporation rates: the neat (or undiluted) oil evaporates much more quickly, so you potentially lose much more oil to the surrounding air when applying them undiluted
- Effects on the skin: pure orange essential oil left the skin looking dry and cracked whereas the diluted orange oil left no visible traces on the skin
- This video concludes that using diluted essential oil produces less waste and is better for your skin
Essential Oil Absorption and Dilution
By taking the time to massage an essential oil thoroughly into your skin, you'll get better absorption because of increased blood flow in that area. Ultimately, this gives your skin a better chance to efficiently absorb all the oil's chemical compounds so you get maximum benefits.
Applying essential oils with a carrier oil and then massaging the skin or applying warm heat (such as a rice bag or moist cloth compress) helps drive the oil deeper into the surrounding tissues. This is especially helpful for promoting feelings of relaxation and lessening tension.

Carrier oils also protect your skin from irritation. Children, the elderly, and those with sensitive skin or compromised immune systems are advised to always use a carrier oil.
Some of the most popular carrier oils include: fractionated coconut oil, virgin coconut oil, jojoba oil, grapeseed oil, almond oil, avocado oil and extra virgin olive oil (affiliate link).
Competing aroma is one main consideration when selecting your own carrier oil because you may not want the smell of your carrier oil to take away from the natural aroma of the essential oil.
Fractionated coconut oil is a popular carrier oil and is created by removing the fatty acids from regular coconut oil. Regular coconut oil is solid at 76 degrees. Fractionating, or removing the fatty acids, keeps the oil in a liquid state, making it easier to use and to combine with essential oils in containers such as spray and roll-on bottles.
The fractionating process also increases shelf life and makes it odorless and colorless. This is a great carrier oil choice to use on your skin and won't clog your pores.
Another great way to dilute and apply essential oils is to combine your essential oil (or essential oil blend) with your favorite unscented lotion. For example, since my sister Brenda (who's a licensed Esthetician here in Arizona) recommends using Frankincense oil (affiliate link) on your skin, I've been adding one drop of Frankincense essential oil to my favorite unscented facial moisturizer (which includes sunscreen) and applying that every morning. After a few weeks of regular use, I can honestly say that the skin on my face has never looked (or felt) better!

Carrier oils are usually cold-pressed oils that are produced from the fatty portions of a specific plant. Carrier oils do not evaporate like essential oils do, but carrier oils can go rancid where your high-quality therapeutic essential oils should not. Instead, essential oils "oxidize" and lose their therapeutic benefits, but they don't go rancid.
Typically most oils purchased at your local grocery store will not be cold-pressed, with the exception of olive oil and a few others, so be sure to read the labels. Oils that are not cold-pressed have been heated during processing and will therefore have minimal therapeutic effect.
Cold-Pressed = unheated = retains beneficial properties
Unrefined = little refining = retains richness and strength
Some carrier oils are odorless, but generally speaking, most have a faintly sweet, nutty aroma. If you come across a carrier oil that has a strong, bitter aroma, the carrier oil may have gone rancid.

Vegetable butters are not carrier oils, but the beneficial properties of vegetable butters like Cocoa Butter and Shea Butter make them suitable for use in aromatherapy.
Vegetable butters are similar to vegetable oils but are solid at room temperature. Vegetable butters are processed by a wide variety of methods, so it's especially important to check the method of extraction when shopping for butters. Always try to use butters that are cold-pressed.
