A Whiff of Trouble: Navigating Allergic Contact Dermatitis to Fragrance.

Fragrances are found in abundance in everyday life-from obvious sources such as perfumes, colognes, and air fresheners, to not-so-common sources, such as workplace exposures. Problematically, even products labeled as "fragrance free" may contain covert fragrances. Patients and physicians alike should be aware that fragrances are a common cause of allergic contact dermatitis (ACD) and that patient education is critical to treatment success. In this review, we discuss the chemistry and epidemiology of fragrance ACD, patch test considerations, skillful patient education on avoidance, and potential pitfalls for patients with fragrance allergy-all to empower treating clinicians with the knowledge to effectively address patient needs.
