Dilution Guide

Essential Oils Dilution

The Appropriate Dose · Topical Application · Dilution Rates

Topical use of essential oils may induce a sensitivity response, especially on young or sensitive skin. To decrease the likelihood of developing a sensitivity, it is advisable to use a carrier oil to dilute the more potent oils and when trying an oil for the first time. To dilute them, add your favorite carrier oil. This process will help "carry" the oils into the skin for better absorption, spread further and protect the skin from irritation. See the chart below.

After application, be aware of adverse reactions for the first 24 hours. Possible reactions include skin irritation, headache, nausea, respiratory complaints or dizziness.
