Allergic contact dermatitis caused by argan oil in an infant.

An 8-year-old girl attended a Halloween party (Fig. 1) where her facewas decoratedwith a colourmake-up pencil. On removing the make-up, she developed erythematous, scaly, itchy patches on the cheeks and perioral area. Hermother applied argan oil on the lesions for some days, which causedaworseningof the rash. Thegirlwas treated in our department with methylprednisolone aceponate cream. Use of the argan oil was discontinued, and the eruption resolved in few days. Patch tests were performed with the European baseline series (TRUE Test®) and the patient’s own products applied with Finn Chambers® on Scanpor® tape. The testswere readaccording to theguidelines of the ICDRGatD2andD4.No reactionswere seen to the True Test® components. A + reaction was seen to the colour pencil and +++ reaction to the argan oil (Fig. 2; both tested ‘as is’). Pure argan oil was tested in the same way in 8 healthy controls, with negative results.
