Microneedling: How It Works and What to Expect

Last updated: October 12, 2026 · Reviewed against current source guidance listed below

What the procedure involves

Microneedling uses fine needles to create tiny punctures in the skin, intended to trigger the body's wound-healing response and stimulate collagen production. It is sometimes combined with platelet-rich plasma (PRP), where a patient's own blood is processed and applied to the treated skin.

Risks and who should avoid it

Reported risks include bruising, temporary redness, scarring, infection, and pigment changes. People with active skin infections, active acne in the treatment area, or a history of keloid scarring are generally not good candidates. Devices that add heat or radiofrequency energy carry additional burn and scarring risk, and regulators have warned that radiofrequency microneedling should only be performed by an experienced, licensed provider.

Microneedling: who should be cautious
Who should be cautiousWhy
Active skin infectionRisk of spreading the infection into deeper skin layers
Active acne in the treatment areaCan worsen inflammation and spread bacteria
History of keloid scarringHigher risk of raised, excess scar tissue
Radiofrequency/heat-based devicesAdded burn and scarring risk — needs an experienced licensed provider

What recovery typically looks like

Mild redness and sensitivity for a few days is common after a standard session; full results, when they occur, tend to build gradually over repeated sessions rather than appearing after a single visit.

Key takeaways
  • Microneedling aims to stimulate collagen via controlled micro-injury to the skin.
  • Risks include infection, scarring, and pigment changes; energy-based devices add burn risk.
  • Not recommended for active skin infection, active acne, or keloid-prone skin.
When to see a doctor
  • Signs of infection after a session: increasing redness, warmth, pus, or fever.
  • Before treatment if you have a bleeding disorder or take blood thinners.
