What is Microneedling?
Microneedling is a minimally-invasive cosmetic procedure that involves using a device to stimulate the natural production of collagen and elastin. Microneedling is safe and effective on all skin types without the risk of discoloration. This procedure can be performed by licensed qualified medical professionals including physicians, osteopaths and naturopaths and is used for many skin conditions.
- Reducing scars caused by acne, surgery or burns.
- Fading stretch marks.
- Reducing fine lines and deep wrinkles.
- Evening skin pigmentation.
- Tightening sagging skin.
What is the procedure like?
The microneedling device used looks like a shaving razor with a drum. The drum can differ in widths and is embedded with up to hundreds of fine micro needles for penetrating the skin. The entire procedure is all-natural and fast:
- The medical professional applies a numbing cream on the treatment area.
- Then rolls the microneedling device across the treatment area, puncturing the skin in a specific pattern.
- As each fine needle punctures the skin, it creates a channel or micro-wound.
- This creates a controlled injury on and below the skin’s surface. The “injury” triggers the body to “fill” these micro-wounds by producing new collagen and elastin, and by stimulating skin cell regeneration.
- The patient resumes regular activities almost immediately.
How does it work?
Microneedling, also known as Collagen Induction Therapy (CIT), works by stimulating the immune system and wound-healing mechanisms. As the tiny needles penetrate the skin causing micro-wounds, it triggers an intense inflammatory reaction that begins a cascade of subsequent reactions. The skin’s nerve receptors and defense mechanisms sense these fine needle intrusions as a specific type of injury and heals accordingly.
During the healing process, skin cells (within a 1 to 2 mm radius around the pricking channel) release growth signals to undifferentiated cells otherwise known as skin stem cells. These signals also stimulate rapid growth of new fibroblasts and other wound repairing cells.
The new collagen fibers thicken the skin, filling in atrophic scars.
Have lots of scarring? The new collagen fibers created from this treatment thicken the skin, filling in atrophic scars. A new layer of skin forms to reveal a new, healthy collagen layer in the treatment area. This reaction is called collagenesis. The wound healing process also stimulates rapid growth of endothelial cells (the thin layer of cells which line capillaries and blood vessels). In turn, this creates new capillaries for better blood supply to the skin. This reaction is called angiogenesis.
During the micro-needling procedure, tissue damage is unlikely because the needles are very fine and thin. In fact, skin integrity actually remains intact even though the skin reacts as if it had been “injured.” The tiny wounds caused by the micro-needles are repaired and close very quickly. No tissue lesion can be detected, infections are rare, and there is nothing to repair.
