Fun Facts - The Science Behind Microneedling and Why It Works

skin health Oct 16, 2023

The scientific mechanism behind microneedling lies in its ability to trigger the body's wound healing response, specifically the release of growth factors and the production of new collagen and elastin.

Here's a more detailed explanation of the science behind this process:

  1. Micro-Injuries and Wound Healing Response: Microneedling creates controlled micro-injuries in the skin, which are perceived by the body as minuscule wounds. In response to these perceived injuries, the body initiates a complex cascade of events known as the wound healing process.

  2. Platelet Activation and Growth Factor Release: When the tiny needles puncture the skin, they cause localized damage to the blood vessels and capillaries. This triggers the activation of platelets, leading to the release of various growth factors, including platelet-derived growth factor (PDGF), transforming growth factor (TGF), and fibroblast growth factor (FGF).

  3. Stimulation of Fibroblasts: Growth factors play a crucial role in stimulating fibroblasts, the cells responsible for producing collagen and elastin fibers. Fibroblasts are activated and recruited to the site of the micro-injuries, where they begin synthesizing and depositing new collagen and elastin.

  4. Collagen and Elastin Production: Collagen is the main structural protein found in the skin, providing it with strength and resilience. Elastin, on the other hand, is responsible for the skin's elasticity and ability to snap back into place. The increased production of these proteins as a result of microneedling leads to skin rejuvenation, firmness, and a reduction in the appearance of wrinkles and fine lines.

  5. Remodeling and Skin Regeneration: As the body continues to heal the micro-injuries, the newly generated collagen and elastin gradually replace the damaged tissue, resulting in a smoother and more youthful skin texture. This remodeling process can help diminish the appearance of scars, improve skin tone, and enhance overall skin quality.


By stimulating the body's natural healing response through microneedling, the skin undergoes a rejuvenation process that ultimately results in improved texture, tone, and firmness, thereby reducing the signs of aging, scars, and other skin imperfections.
