What statement about microneedling is true?

• A. It increases collagen production.
• B. It increases blood flow without affecting collagen.
• C. It induces collagen production.
• D. It has no effect on the skin.

Answer: (C)

Controlled micro-injury triggers a wound-healing response that drives collagen production. By creating tiny punctures, microneedling prompts growth factors and fibroblasts to synthesize collagen and elastin, remodeling the dermal matrix over time. This makes the statement that microneedling induces collagen production the most accurate description, because it reflects the biological response to the treatment rather than just a change in blood flow or no effect at all. While increased blood flow and factor release occur alongside the process, the key outcome is the induction of collagen synthesis, which underlies the improved skin texture and firmness seen after treatment.
