Microneedling creates controlled micro-injuries in the skin to trigger a natural wound-healing response. This process stimulates the production of new collagen and elastin, key structural proteins that decline with age. From a healthspan perspective, this improves the integrity, thickness, and resilience of the skin, which is the body's largest organ and primary environmental barrier.
Verdict
Effective for skin appearance; unproven for systemic healthspan or longevity.

Flags
- Risk of infection, scarring, or hyperpigmentation is elevated with improper technique or at-home devices.
