Microneedling is a form of therapy that utilizes instruments containing rows of thin needles that penetrate the dermis to a uniform depth, creating a controlled skin injury. This controlled skin injury induces rapid healing micropunctures with subsequent collagen and elastin fiber production stimulation, resulting in skin remodeling. Microneedling was initially developed as a tool for skin rejuvenation. However, it is now being used for several indications, which include various forms of scars, alopecias, drug delivery, hyperhidrosis, stretch marks, and more. It is occasionally combined with radiofrequency energy delivery, which is thought to enhance dermal remodeling and clinical effects. Microneedling is a commonly used procedure in dermatology. It is considered a safe and inexpensive alternative to other forms of skin rejuvenation that is well-tolerated with minimal downtime. Despite its common use and wide variety of indications, strong evidence for the efficacy of microneedling is not evident in the literature.
微针疗法是一种治疗方式，它使用含有成排细针的器械，这些细针可穿透真皮至统一深度，造成可控的皮肤损伤。这种可控的皮肤损伤会引发快速愈合的微小穿刺，随后刺激胶原蛋白和弹性纤维的生成，从而实现皮肤重塑。微针疗法最初是作为一种皮肤年轻化工具而开发的。然而，它现在被用于多种适应症，包括各种瘢痕、脱发、药物递送、多汗症、妊娠纹等等。它偶尔会与射频能量递送相结合，这被认为可以增强真皮重塑和临床效果。微针疗法是皮肤科常用的一种治疗手段。它被认为是一种安全且廉价的替代其他皮肤年轻化方式的方法，耐受性良好，恢复时间极短。尽管其使用广泛且适应症多样，但微针疗法疗效的有力证据在文献中并不明显。
