Abstract
Microneedling (MN) and microcoring (MCT) are both methods used for percutaneous collagen induction. This minimally invasive technique involves creating controlled damage in cutaneous tissue to induce neocollagenesis and neoelastogenesis. MN utilizes solid microneedles and is commonly combined with radiofrequency (RF) to add thermal energy, while MCT involves hollow microneedles capable of removing excess tissue without inducing scar formation. The purpose of this review was to summarize recent literature for MN and MCT, with the goal of assisting clinical decision making regarding the use of these technologies. PubMed search was conducted for relevant articles published within the last 10 years. Scoping literature review was then performed with pertinent findings reported. Existing literature investigating MCT is sparse. Limited data on invivo, human effects of this technology exist. Two out of 14 studies in this review pertained to MCT. Additional high-powered clinical studies are needed to guide future cosmetic treatments with MN and MCT.
