Postinflammatory Hyperpigmentation following Electrodesiccation with a Eutectic Mixture of Local Anesthetics.

ABSTRACT

We assessed the effects of prior application of a eutectic mixture of local anesthetics (EMLA) on the appearance of dyschromia at the site of superficial electrodesiccation in an observer-blind, case-control study in 60 patients. Thirty subjects each were assigned to Groups A and B; both groups underwent radiofrequency (RFC) ablation for facial dermatosis papulosa nigrans (DPN). Group A received RFC ablation with prior application of EMLA, whereas Group B did not. No significant difference was observed in the dyschromia between both groups. EMLA cream was well tolerated by the study participants. (SKINmed. 2020;18222-225).
