What is true of microneedling?

• A. It induces collagen production.
• B. It decreases collagen production.
• C. It hydrates skin without any other changes.
• D. It eliminates the need for sunscreen.

Answer: (A)

When skin is punctured with tiny needles, it creates controlled micro-injuries that awaken the skin’s healing process. This repair response activates fibroblasts to produce new collagen and elastin, rebuilding the dermal matrix. Over the coming weeks to months, the newly laid collagen remodels the skin, improving texture, reducing fine lines, and helping with scar appearance. That is why the statement that microneedling induces collagen production is true and central to how the treatment works.

It doesn’t decrease collagen production, and the effect isn’t simply hydration—the hydrating impact is more about the products used during and after the procedure rather than the microneedling itself. Sunscreen remains essential after microneedling because the skin is more sensitive to sun exposure during and after the healing process. While serums may be applied to boost results, the core mechanism is the induction of collagen production.
