For adults (teens and grown-ups), farnesol is usually low risk when used on the skin, but it can cause allergic skin reactions in people who are sensitive to fragrances.
If you plan to use a product that lists farnesol or “fragrance,” do a small patch test on your inner forearm and wait 24–48 hours. Stop use right away if you get redness, itching, swelling, or a rash. If you have a history of fragrance allergies or very sensitive skin, choose fragrance-free products instead. Don’t apply to broken or irritated skin.
Watch for allergic skin reactions. Regulatory groups (for example the European Union cosmetics rules and the International Fragrance Association) list farnesol as a known or possible allergen and require labeling or limits in cosmetics. The European Chemicals Agency has also reported limited evidence of skin irritation or allergy. If you develop a rash, consult a healthcare provider or dermatologist and check product labels for farnesol or fragrance ingredients.
