Essential Oil Dilution Calculator

For leave-on skincare, 1–2% is the usual safe everyday dilution (about 3–6 drops per 10 mL carrier). Higher dilutions (up to 5%) are only for short-term or localised use.

Apply a small amount of your blend to the inside of your forearm and wait 24 hours before wider use, to check for any irritation or sensitivity.

Essential oils are potent. Using more doesn’t always mean better results, and lower dilutions are often more effective and safer over time.
