Derma-rolling, also known as micro-needling or collagen induction therapy is a process of puncturing the skin repeatedly with micro needles to achieve several therapeutic effects. It was initially used to treat wrinkles, scars, and hyperpigmentation on patients as doctors discovered that these patients were responding positively to hypodermic needle punctures.
Doctors had discovered that puncturing the skin with needles was breaking down collagen and realigning it. Over time with more research, it was discovered that micro needling was a successful way to treat other skin conditions besides scars.
It became apparent that the micro-needling procedures were doing just enough superficial damage to the skin to provoke the body’s natural healing response, which in turn induced the production of elastin and collagen as well as increasing blood flow and other growth factors to the area and which lead to smoother, tighter, younger skin.
Over time, doctors would discover that micro-needling could also be used to increase the absorption of products applied to the skin as well as to combat hair loss by taking advantage of the same healing response that was repairing blemishes and rejuvenating the skin.
