Essential Oils Dilution Chart

Essential oils are highly concentrated plant extracts and should usually be diluted before applying them to the skin. Proper dilution helps reduce the risk of skin irritation while allowing the oils to be used safely in aromatherapy and topical blends.

This essential oil dilution chart provides a quick reference for common dilution percentages and the number of drops needed when blending essential oils with carrier oils. It can help beginners and experienced users prepare safe aromatherapy blends for massage oils, skincare, and everyday use.

Why Dilution Is Important

Essential oils are extremely potent and applying them directly to the skin may cause irritation or sensitization. Diluting essential oils with a carrier oil helps reduce their concentration while still allowing their aromatic properties to be enjoyed.

In aromatherapy, a 3–5% dilution is commonly used for daily topical applications, while lower dilutions are recommended for sensitive skin, children, or facial products.
