What skin response is triggered by micro needling?

1. A wound response

2. Skin exfoliation

3. Cleansing of the pores

4. Increased collagen production

The correct answer is: A wound response

Micro needling involves the use of fine needles to create micro-injuries in the skin, which triggers the body’s natural healing process. This process is known as a wound response. When the skin detects these tiny injuries, it initiates a series of biological events aimed at repairing the damage. During this healing process, various growth factors are released, and the body increases the production of collagen and elastin, which are essential for maintaining skin elasticity and firmness. While the increased collagen production that follows is a significant outcome of the wound response, the primary skin response that micro needling triggers is indeed the wound healing process itself. This response is essential for rejuvenating the skin, reducing the appearance of scars, improving texture, and minimizing fine lines. Thus, understanding the concept of the wound response is crucial for grasping how micro needling enhances the overall quality and appearance of the skin.
