Allergic contact dermatitis caused by (meth)acrylates in long-lasting nail polish - are we facing a new epidemic in the beauty industry?

BACKGROUND

Allergic contact dermatitis (ACD) caused by (meth)acrylates has been described both in occupational and in non-occupational settings.

OBJECTIVES

To evaluate the clinical patterns, the most frequent allergens and the prognosis in patients sensitized to (meth)acrylates in long-lasting nail polish.

METHODS

The files of patients with ACD caused by (meth)acrylates in long-lasting nail polish diagnosed between January 2013 and June 2016 in four dermatology departments in Spain were reviewed. Patients were followed up by telephone interview.

RESULTS

Overall, 2353 patients were patch tested. Forty-three (1.82%) were diagnosed with ACD caused by (meth)acrylates in long-lasting nail polish during that period; all were female, and all had hand dermatitis. Patients were mostly less than 40 years old (72.1%), non-atopic (95.4%) and had an occupational cause of their dermatitis (93%), which developed ∼10.1 months after they had started to use this technique. The most frequent positive allergens were: 2-hydroxypropyl methacrylate, 2-hydroxyethyl methacrylate, and tetrahydrofurfuryl methacrylate. Eight of the 22 interviewed patients were able to improve their working technique and used 4H® protective material (fingerstalls/gloves).

CONCLUSIONS

Long-lasting nail polishes have become widespread, and it is a matter of concern that we may be facing a new epidemic of ACD caused by these. Policies regulating their use are urgently needed.
