“…9 A case of ACD in a patient using neem oil to treat AD has also been previously reported, 10 as well as a case of occupational ACD in a worker who manufactured 'natural' soaps and creams. 11 Of note, the clinical presentation of ACD to neem oil in these reports did not specifically include micropapular or follicular lesions. To our knowledge, this clinical pattern has not yet been reported in cases of ACD from neem, nor from argan, olive or jojoba oils.…”

The Curasept ® mouthwash is marketed in Italy as a medical device. In this case the presence of MI in the mouthwash was correctly declared in the label by the manufacturer and this facilitated the diagnosis. However, the current regulations concerning medical devices do not require the complete declaration of all the ingredients in the label. 6 A more stringent regulation about the complete declaration would be highly desirable. At the same time a more stringent regulation about MI content in medical devices should be considered, with the aim of reducing the incidence of allergic contact dermatitis due to isothiazolinones in these products.

Adverse cutaneous reactions, some of which are allergic in origin and of variable severity, occur from systemic administration of medicaments, and others result from contact sensitivity from their topical use. Allergic contact dermatitis (ACD) to topically applied medicaments, excipients or active ingredients, is encountered frequently in clinical practice and should be suspected in all at-risk individuals. Although about one-third of all cases of ACD are initiated or perpetuated by prescribed or non-prescribed topical preparations, the problem usually remains underappreciated. The prevalence of hypersensitivity to these allergens varies across regions and periods of time depending on the personal habits and health-seeking behavior of an individual, the interest of the clinician in the field of contact dermatitis, and the types of cases studied. Often promoted by social media influencers as a remedy for all dermatological problems or cosmetics, the use of several home remedies and other over-the-counter anti-aging and cosmetic products has increased exponentially in recent years. We, herein, briefly review some of the commonly used products potentially causing ACD.
