Dilution Guidelines

  • Follow safe ranges

    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. Stronger blends (10–20%) are used for perfumes only.

  • Always patch test

    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.

  • Less is more

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