Optimization of Impedance Spectroscopy Techniques for Measuring Cutaneous Micropore Formation after Microneedle Treatment in an Elderly Population


The objective of this study was to optimize a reproducible impedance spectroscopy method in elderly subjects as a means to evaluate the effects of microneedles on aging skin. Human volunteers were treated with microneedles at six sites on the upper arm. Repeated impedance measurements were taken pre- and post-microneedle insertion. Two electrode types were… (More)
