The Mechanism of Action Behind Microneedling Treatment

You are already aware of the many benefits that microneedling offers to those who undergo the treatment. The next question that you may have is how the procedure works.

This article is a brief guide on microneedling and how each of its components works towards giving you flawless, ageless, and blemish-free skin.

Why does microneedling involve puncturing the skin?

The creation of micro-injuries creates controlled injuries on the superficial layer of the skin; just enough depth to trigger the healing process. It does not damage the epidermal layer of the skin. Once the wound healing process starts, various growth factors are produced including connective-tissue activating protein and fibroblast growth factors.

The needles also contribute to the breakdown of scars while allowing the skin to revascularize yet again. 

How deep should the micro-injuries be to induce collagenesis?

Once fibroblasts have formed a matrix on healing skin, the process of collagen production occurs. The deposition of collagen that leads to skin tightening usually happens 7 days after microneedling treatment. For effective collagen production of up to 5 micromillimetres, a 1- 1.5 mm needle length is to be used. Using the right needle length for your skin, you can expect an increase of up to 400% collagen production after 4 sessions of microneedling spaced 4 weeks apart.

How does microneedling enhance the absorption of skincare products?

Microneedling greatly enhances the skin’s absorbing abilities as it allows the entry of nutrients directly into the vascularized layer of the skin. As new skin surfaces, the scales and oil that arises from the superficial layers of the skin are bypassed, too.
