Derma Rolling

Derma Rolling, Medical Skin Needling

Medical skin needling, also known as collagen induced therapy and Dermal Roller. The skin is numbed and then an instrument-roller, laden with tiny needles is rolled across the skin. The needles penetrate to a depth corresponding to the dermis.

​

Micro-needling is a minimally invasive skin rejuvenation procedure that helps minimize the signs of aging, treats the scars,including post-acne scars and scars after operation. The micro-needling device causes controlled micro-injuries that stimulate the body’s natural wound healing process. The micro-injuries trigger the release of cytokines and growth factors that lead to remodeling of collagen and elastin.

​

There are three phases to the wound repair process:

Phase I: Inflammation. Piercing the skin triggers your immune system to disinfect the wounds, remove debris, increase blood flow and begin to create new tissue.

​

Phase II: Proliferation. The wound is re-built with new granulation cells, as well as a temporary (type III) collagen and elastin, which are part of the extracellular matrix. Additionally, a new network of blood vessels develops.

​

Phase III: Remodeling. The wound has been replaced with new dermal tissues and blood vessels. The type III collagen in the newly formed tissue is replaced with stronger type I collagen, which can contract to create a tightening or “shrink wrap” effect on the skin.
