Skin needling, also called microneedling therapy, collagen induction therapy (CIT), and percutaneous collagen induction (PCI), is a minimally invasive skin-rejuvenation procedure that involves the use of a device that contains fine needles. The very fine needles are used to puncture the surface of the skin to create a controlled skin injury. Each puncture creates a channel that triggers the body to fill these microscopic wounds by producing new collagen and elastin. Through the process of neovascularization and neocollagenesis, there is improvement in skin texture and firmness, as well as reduction in scars, pore size, and stretch marks.
“Microneedling is a safe, chemical-free method that triggers new collagen production. Because it can be performed on all skin colours and types, it is often the preferred treatment over laser as there is no risk of burning the patient the client.
It is clear that microneedling is poised to explode in the near term, and we can expect to see more clinical data to confirm claims that doctors are seeing in their practices. There has been a sea change from what once was marked scepticism to almost widespread acceptance of this category of skin treatments. Microneedling is now being performed by dermatologists and plastic surgeons around the world.
