Abstract: Described herein are technologies, methods, and/or devices for treating skin (e.g., eliminating tissue volume, tightening skin, lifting skin, and/or reducing skin laxity) by selectively excising a plurality of microcores without thermal energy being imparted to surrounding (e.g., non-excised) tissue. The technologies, methods, and/or devices described herein satisfy an unmet need for rapid and safe treatment of skin, including, e.g., faster pretreatment preparation and post-treatment healing times compared to current surgical and thermal treatment methods.
