Essential Oils Safety Advice
Essential Oil Safety Advice
This page explains how to use essential oils safely, including dilution, storage, phototoxicity, and special cautions. For quick answers, see our Essential Oils & Aromatherapy FAQs.
Contents
Introduction
Essential Oils should always be diluted in a base product (usually a carrier oil like sweet almond or Jojoba oil) before being applied to the skin. In fact in the UK it is actually illegal to say that an essential oil can be applied directly to the skin. You can link to our Essential Oils and Carrier Oils categories.
Dilution Guidelines
Keep to the suppliers recommended dosages and dilutions. Here is a table to give guidelines for some milder essential oils, like lavender and roman chamomile.
| Use Case | Typical Dilution | Example (per 10 ml carrier) |
|---|---|---|
| Daily body application (adult) | 0.5%–2% | 1–4 drops total |
| Short-term / targeted | up to 2% | 4 drops total |
| Facial skin / sensitive | 0.5%–1% | 1–2 drops total |
Always dilute in a carrier oil, unscented lotion or cream and perform a patch test.
Topical Use & Patch Testing
Once diluted correctly, in a carrier oil, lotion or cream, essential oils can be applied to the skin. We would always recommend doing a patch test first. Avoid eyes/mucous membranes. Discontinue use if irritation occurs. See Aromatherapy Tips.
Ingestion of Essential Oils
Essential oils are for external use only. Never take internally unless advised by a medical professional. Essential oils are highly concentrated and can even be toxic in certain cases.
Citrus & Phototoxic Essential Oils
Certain citrus oils are photosensitive and you should therefore avoid going in the sun for at least 12 hours after using them.
The following essential oils are phototoxic and you should avoid going into the sun, or on a sunbed, for at least 12 hours after using them:-- Lemon Essential Oil
- Orange Essential Oil
- Grapefruit Essential Oil
- Mandarin Essential Oil
Essential Oils in Pregnancy
If you are pregnant, some organisations advise that essential oils should be avoided altogether.
Other authoritative bodies, advise that certain essential oils can be used during pregnancy, however, we would always recommend consulting a qualified aromatherapist if you are pregnant and considering using essential oils.
Some essential oils should be avoided throughout pregnancy including:-
- Basil, sweet Essential Oil

Other essential oils should be used in half the quantity or less during pregnancy or as guided by the qualified aromatherapist.
Children & the Elderly
Do not use on children under 3, without prior consultation from a qualified aromatherapist. Dilutions for children and the elderly should be at least half the recommended dose and professional advice should always be obtained if you are uncertain. Always keep out of reach of children.
For further information using essential oils with children, the International Federation of Aromatherapists (IFA) have issued these guidelines
