Microneedling

Excerpt

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.
