What is a carrier oil?
A carrier oil is a base oil used to dilute essential oils and absolutes before they are applied to the skin.

Safety 1st Essential Oil Dilution Guide:
- It’s is best to start with the lowest dilution rate possible when applying an essential oil for the first time, you can always increase the percentage up to 5% over time.
- When applying a new essential oil to the skin a skin patch test can be helpful. To do so add one drop of essential oil to a cotton ball. Swipe it on the inside of your arm if redness, inflammation, or itchiness occurs within 15 to 20 minutes you may be sensitive to it.
- If an essential oil is “neat” you may want to dilute it for children, during pregnancy, or for those with sensitive skin.
- Some herbalist and aromatherapists may recommend diluting further – adding more carrier oil is always O.K.
