For adults: mostly safe for people without fragrance sensitivity. The biggest issue is allergic skin reactions (redness, itching, rash) in those who are sensitive to fragrances.
If you have normal skin, occasional use in rinsed-off products (shampoos, body washes) is usually low risk. If you have sensitive skin, eczema, or know you react to fragrances, choose fragrance-free products or those that do not list Hexyl Cinnamal. Before using a new leave-on product (lotions, perfumes), do a simple patch test: put a small amount on the inside of your forearm, wait 24â48 hours, and watch for redness or itching. Avoid applying to broken or inflamed skin.
Stop use and wash the area if you get redness, itching, swelling, or a rash after using a product. Seek medical care for severe or spreading reactions. Regulatory listings (for example the EU cosmetics allergen rules and chemical agency findings) flag this ingredient as a known fragrance allergen and require labeling in some regions, so check ingredient lists. Although there is limited animal evidence of hormone effects at high doses and limited irritation concerns, these are considered low-level worries for adults; the main practical risk is allergic reaction.
