甲醛可能令部分人士产生皮肤刺激反应,美国接触性皮肤炎协会(ACDS)更将甲醛列为2015年的「年度致敏物质」。有研究指,较高浓度的甲醛(200至300ppm)可致皮肤炎,如有伤口、易敏感皮肤或湿疹人士更要小心。

Bronopol is an antimicrobial preservative that works by forming formaldehyde in cosmetic products. People exposed to such formaldehyde-releasing ingredients may develop a formaldehyde allergy or an allergy to the ingredient itself. In the U.S. approximately 20% of cosmetics and personal care products contain a formaldehyde-releaser and the frequency of contact allergy to these ingredients is much higher among Americans compared to studies in Europe.
