Microneedles provide an artificial pathway across skin barrier for medical and cosmetic applications. The use of multiple small needles mounted on a roller to pierce the skin to stimulate collagen production has undergone a new interest. This monograph draws on how to integrate microneedle technology into clinical dermatologic practice.

Microneedles provide an artificial pathway across the skin barrier for medical and cosmetic applications. This technology has seen a significant increase in popularity over the past years; as an example, the use of multiple small needles mounted on a roller to pierce the skin, prompting it to stimulate collagen production, has undergone a resurgence of interest as an adjunctive procedure for a number of skin disorders. This monograph draws together what is known about how to integrate microneedle technology into clinical dermatologic practice.
