Functional Microarray Augmentation of Skin Treatment With Lidocaine

Functional Microarray Augmentation of Skin Treatment With Lidocaine (FAST Lidocaine)

The purpose of this study is to determine whether co-application of a functional microarray of needles (FMA) speeds the rate at which topical anesthesia is provided. A secondary goal is to determine whether the depth of anesthesia is enhanced.

The study's primary goal is to determine whether co-application of a functional microarray of needles (FMA) speeds the rate at which topical anesthesia is provided by lidocaine gel 4% (LG4). A secondary goal is to determine whether the depth of anesthesia is enhanced.
