Allergic contact dermatitis caused by ascorbyl tetraisopalmitate

A 54-year-old non-atopic woman presented at our outpatient clinic with a history of a skin reaction 2 days after the first application of an anti-ageing skin care product, Hydracyd C 20 cream® (Laboratoires SVR, Le Plessis-Pâté, France). The reaction had started on the face, and spread to the arms and pre-sternum. One week before the onset of the skin complaints, the patient had been exposed for 2 days to a new acrylic wall paint. She had regularly come into contact with other acrylic paints, without any problems. Patch testing with the European baseline series (Trolab®; Hermal, Reinbek, Germany), a cosmetic series, a pharmaceutical series and her own products was performed, using van der Bend patch test chambers (van der Bend, Brielle, The Netherlands) applied on Micropore® (3M Health Care, Borken, Germany), and fixed with Mefix® (Mölnlycke Health Care, Göteborg, Sweden). The readings were performed according to the guidelines of the International Contact Dermatitis
