The incidence of ACD increased until 2016 after which it started to decrease. The increase was more marked in females and ACD was particularly common in women reporting reactions to cosmetics and other chemical products and in people of both sexes reacting to adhesives. The incidence \u2018ACD of unspecific cause\u2019 has decreased since 2016. The most commonly reported allergens were metals, followed by cosmetics.
