For adults (grown-ups, teens): Isoeugenol is a fragrance chemical that can cause skin allergy in some people. Most adults can use products that follow safety rules, but people with sensitive skin or known fragrance allergies are more likely to react.
Check product labels for 'isoeugenol' or generic 'fragrance.' If you have sensitive skin, choose fragrance-free products. When trying a new product that contains isoeugenol, do a small patch test on the inside of your wrist or behind your ear and wait 24–48 hours. Don’t put products with isoeugenol on broken or irritated skin. If you get redness, itching, or a rash, stop using the product and see a healthcare provider.
This ingredient is listed as a known skin allergen and has use limits and labeling rules under the European Cosmetics Directive. The European Chemicals Agency and the fragrance industry group have reported evidence of skin reactions. Watch for any allergic reaction (redness, itching, swelling, blisters) especially if you have a history of fragrance sensitivity. If you are pregnant and unsure, choose fragrance-free options to reduce unnecessary exposure (note: reproductive concerns are rated low).
