Abstract：
BACKGROUND: 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.
OBJECTIVE: 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.
METHODS: PubMed search was conducted for relevant articles published within the last 10 years. Scoping literature review was then performed with pertinent findings reported.
RESULTS: Existing literature investigating MCT is sparse. Limited data on in vivo, human effects of this technology exist. Two out of 14 studies in this review pertained to MCT.
CONCLUSIONS: Additional high-powered clinical studies are needed to guide future cosmetic treatments with MN and MCT.

摘要：
背景：微针（MN）和微取芯（MCT）都是用于经皮胶原蛋白诱导的方法。这种微创技术涉及在皮肤组织中产生受控损伤以诱导新生和新弹性生成。MN利用实心微针，通常与射频（RF）结合使用以增加热能，而MCT涉及能够去除多余组织而不诱导瘢痕形成的中空微针。
目的：这篇综述的目的是总结MN和MCT的最新文献，目的是协助有关使用这些技术的临床决策。
方法：PubMed搜索最近10年内发表的相关文章。然后进行范围界定的文献综述，并报告相关发现。
结果：研究MCT的现有文献很少。体内数据有限，这种技术对人类的影响是存在的。本综述的14项研究中有2项与MCT有关。
结论：需要更多的高性能临床研究来指导未来MN和MCT的美容治疗。
