For adults (including teens and young adults), eucalyptol is usually safe on the skin but can cause allergic skin reactions or irritation in some people.
Before regular use, test a small amount on the inside of your forearm and wait 24 hours. Don’t apply to broken, irritated, or inflamed skin. Keep products away from eyes, nose, and mouth. If you have a history of fragrance allergy or sensitive skin, choose products without eucalyptol or use very small amounts.
Watch for redness, itching, swelling, or blisters — stop use if these happen. The warning about allergic reactions comes from the U.S. EPA and the European Chemicals Agency, which have reported evidence of skin allergy and limited dermal reactions. If you get a strong reaction or have breathing trouble, seek medical help.
