Microneedling is known to cause what physiological effect?

Microneedling is primarily recognized for its ability to stimulate the body's natural healing processes, which leads to an increase in growth factors. When the microneedling procedure is performed, tiny, controlled injuries are created in the skin, prompting a response that includes the release of growth factors. These growth factors play a crucial role in tissue repair and regeneration, promoting cellular turnover and encouraging the production of new collagen and elastin. This physiological effect ultimately contributes to improved skin texture, firmness, and elasticity, making microneedling a popular treatment for various skin concerns.

In contrast, a decrease in blood circulation would not align with the mechanisms of microneedling since the procedure encourages increased blood flow to the treated area as part of the healing response. The thinning of the dermis and a reduction in collagen synthesis would also be contrary to the intended outcomes of microneedling, as the goal is to enhance dermal thickness and promote collagen production rather than to diminish it.
