Which essential oils do not have to be diluted for use?

• A. Tea Tree and Lavender
• B. Peppermint and Eucalyptus
• C. Lemon and Orange
• D. Rose and Geranium

Answer: (A)

The idea being tested is which essential oils are gentle enough to be used without dilution for topical use. Lavender and tea tree are two of the gentler options and are commonly used directly on small skin areas or simple skincare concerns, especially in adults, because they tend to be better tolerated and have a long history of safe use in little amounts. This doesn’t mean they’re risk-free—skin sensitivity can vary—so caution and patch testing are still wise, particularly for children, pregnant individuals, or those with sensitive skin. In contrast, the other oils are more likely to cause irritation or adverse reactions if applied undiluted. Peppermint and eucalyptus carry stronger menthol-like effects and can irritate or burn the skin, especially in sensitive individuals. Citrus oils like lemon and orange are more likely to provoke skin sensitivity and are also photosensitive, meaning they can increase sensitivity to sunlight. Rose and geranium, while often pleasant and beneficial in skincare, can still irritate some skin types if used neat, so dilution remains a common precaution.
