For adults, citronella oil is usually safe on the skin when it is used in products at normal, diluted amounts. It can cause mild irritation or allergic reactions in some people. There is also a note that some samples have shown contamination concerns.
Use only products meant for skin (not pure undiluted oil). Do a small patch test on your inner forearm and wait 24 hours before wider use. Stop use and wash the area if you see redness, itching, swelling, or any rash. Choose brands that test their ingredients and list safe dilution levels. If you are pregnant, breastfeeding, or have a history of strong skin allergies, check with your healthcare provider before using.
Avoid putting undiluted citronella essential oil directly on skin. Watch for signs of irritation or allergic reaction (redness, itching, hives, blisters). There have been contamination concerns noted in ingredient safety records, including possible traces of formaldehyde in some batches, and some product verification programs restrict its use unless tested. If you have any breathing problems after use, seek medical help right away. Source notes: contamination and regulatory findings listed in the ingredient safety information (including Environment Canada and European chemical safety notes).
