Lanolina

Lanolin-induced contact dermatitis

Authors of a study published in Dermatitis sought to determine characteristics, detection, and prevalence of lanolin-induced contact dermatitis. Lanolin, the 2023 contact allergen of the year, is a weak sensitizer with an estimated 0.4% of the European population demonstrating contact allergy to it. Despite this low prevalence, certain patients are more susceptible to lanolin contact allergy, including the young and elderly and those with stasis dermatitis, leg ulcers, perianal/genital dermatitis, or atopic dermatitis. Lanolin may produce a false-negative patch test in these patients when tested on normal skin.

Pediatric dermatologists share clues for distinguishing contact dermatitis from atopic dermatitis and discuss noteworthy allergens. Read more in DermWorld.
