Carrier oils are usually vegetable oils that come from their seeds, nuts, or plant kernels. Most essential oils should not be applied directly to the skin, so they have to be diluted with carrier oils or other ingredients. These oils, when combined with essential oils, are also used in many beauty products such as sugar scrubs, lotions, balms, moisturizers, perfumes, and more. Carrier oils are usually odorless except some types of coconut oil, sesame seed oil, and hemp seed oil.
The term Comedogenic as it pertains to carrier oils and essential oils is a determination of whether or not certain oils with a rating of 0-5 will cause your skin to breakout because of clogged pores. Essential oils on their own are non-comedogenic, but in most cases you will be using them with some sort of carrier oil. The types of commonly used carrier oils have comedogenic ratings from 0-5 based upon how likely they are to clog pores and cause breakouts. This is a great resource containing additional oils and their comedogenic ratings.
Here is a breakdown of the ratings:
Comedogenic rating of 0 means that the oilis a non-comedogenic and will not clog your pores.
Comedogenic rating of 1 has a slight chance of clogging your pores.
Comedogenic rating of 2 means that most people will not have clogged pores, but some people will experience clogged pores depending on their skin type.
Comedogenic rating of 3 will cause a lot of people to experience clogged pores or breakouts even though others won't experience any problems depending on their skin type.
Comedogenic rating of 4 suggests that most people will experience clogged pores or breakouts unless they have a good tolerance to oils depending on their skin type.
Comedogenic rating of 5 basically guarantees clogged pores and breakouts because very few people can tolerate oils with this rating.
All of the carrier oils, specialty oils, hydrosols, ingredients, and some herbal infused oils can be purchased at Mountain Rose Herbs, StillPoint Aromatics, Aromatics International, Whole Foods, or on Amazon.
