Key takeaways
- Microneedling prompts the skin to make new collagen and is especially useful for acne scars.
- Adding radiofrequency gives better results than either treatment alone.
- It's safe for all skin tones, one of its main advantages.
- Acne scars usually need 3 to 5 sessions every 2 to 4 weeks.
- Recovery is short: redness for a few days, and you can go back to work straight away.
What is microneedling?
A device with very fine needles makes tiny, controlled punctures in the skin. The skin responds to this small injury by making new collagen, so texture improves and scars soften gradually.
What does radiofrequency add?
In RF microneedling the needles deliver heat energy to a set depth in the skin. The combination makes acne scars less noticeable than radiofrequency or microneedling alone, and it remains safe for all skin tones.
Microneedling may also be combined with a chemical peel or PRP to improve results.
What does it treat?
- Acne scars.
- Scars from surgery or injury.
- Large pores.
- Uneven skin texture and tone.
- Fine lines, wrinkles and mild sagging.
- Stretch marks.
- Dark spots and melasma, as part of a plan set by your doctor.
How many sessions, and when do results show?
| Item | Typical |
|---|---|
| Number of sessions | 3 to 5 |
| Spacing | Every 2 to 4 weeks |
| First improvement | Within a few weeks |
| Full results | After several months |
| How much improvement | In studies, scars faded by 50% to 70% |
| Maintenance | A yearly session may be advised because collagen declines over time |
Recovery after a session
- Redness or slight darkening lasting a few days to a week.
- You can return to work or school straight away.
- Wait 24 hours before applying makeup.
- Use sunscreen every day during the treatment course.
Why we don't recommend at-home devices
At-home devices give weaker results, carry a risk of infection and scarring, and can spread warts, herpes and other viruses to new areas of the face.
Who shouldn't have microneedling?
- People who heal poorly or tend to form keloids.
- People with a weakened immune system.
- People having chemotherapy or radiation for cancer.
- People who recently took isotretinoin; wait at least one month.
Compared with fractional CO₂ laser
Fractional CO₂ may give greater improvement in scars, but with longer recovery and a higher risk of pigmentation in darker skin. RF microneedling is gentler and safer for darker skin, so Dr. Yousef chooses between them based on scar type and skin tone.
Common questions
- Does it hurt? A numbing cream is usually used, and most people find it tolerable.
- Is it safe for brown or dark skin? Yes, it's safe for all skin tones.
- Do results last? They last a long time, but collagen declines with age, so a yearly maintenance session can help.
