RF Microneedling for Acne Scars and Large Pores

RF microneedling is one of the more effective treatments for rolling and boxcar acne scars and for enlarged pores. It combines fine needles with radiofrequency energy to remodel collagen in the deeper layers of the skin. Most people need a course of around three sessions, four to six weeks apart, and see steady improvement over the following months.

It softens and smooths scarring rather than erasing it. Here’s what it involves and what you can realistically expect.

How does RF microneedling work?

Standard microneedling creates tiny channels in the skin to trigger healing. RF microneedling goes further. The needles deliver radiofrequency heat directly into the dermis, where scar tissue and pore structure sit.

At the clinic, Tanya uses the Lutronic Genius. Its needles are insulated, so the heat is released at the tip, deep in the skin, while the surface stays relatively protected. Depth and energy can be adjusted for each area, which matters on a face where scarring is rarely even.

Which acne scars respond best?

Acne scars come in different shapes, and they don’t all respond in the same way:

Rolling scars, with soft, wave-like edges, often respond well because the treatment loosens and rebuilds the tissue underneath
Boxcar scars, with broader, defined edges, usually improve, particularly shallower ones
Icepick scars, which are narrow and deep, are the hardest to shift and may need other approaches alongside

Most people have a mix. Tanya will assess yours at consultation and be honest about how much change is likely.

What about large pores?

Pores look larger when the skin around them loses firmness, or when they’re stretched by oil and congestion. The collagen tightening from RF microneedling helps the surrounding skin hold pores more tightly, so they look smaller and the skin looks smoother overall. Keeping oil under control with the right skin care helps the results last.

What happens during treatment?

Numbing cream is usually applied first to keep you comfortable. The treatment itself takes between 20 and 45 minutes, depending on the area. You’ll feel pressure and some heat as the handpiece moves across the skin.

How much downtime is there?

Expect redness, warmth and some swelling for up to 72 hours. Most people can wear makeup the next day and are back to normal activities within one to two days. Plan your first session for a time when looking a little flushed for a day or two won’t matter.

How many sessions, and when will I see results?

A typical course is three sessions, spaced four to six weeks apart, with maintenance as needed afterwards. Collagen renewal starts straight away and continues for months, so improvement is gradual. Most people notice the clearest change six to twelve weeks after their final session.

Published research on fractional RF microneedling for acne scars is encouraging. Across several studies, most patients showed moderate or better improvement, and side effects were mainly short-lived redness. The studies are small, though, and results vary from person to person.

Is RF microneedling suitable for darker skin?

Because the surface of the skin is largely protected, RF microneedling carries a lower risk of pigmentation changes than many lasers. Studies including people with darker skin tones have reported few cases of post-inflammatory pigmentation. Tanya will still adjust settings carefully for your skin type and may suggest preparing the skin beforehand.

Get active acne under control first

RF microneedling treats scars, not active breakouts. If you’re still getting spots, the first step is to calm them down, usually with medical-grade skin care and, where suitable, treatments such as LaseMD Ultra or a skin peel. Once the skin is settled, scar treatment works better and the risk of flare-ups is lower.

Let Tanya know if you’ve taken isotretinoin (sometimes called Roaccutane) recently, if you’re pregnant, or if you tend to form raised or keloid scars. These can affect whether, or when, treatment is right for you.

Frequently asked questions

Does RF microneedling hurt?

Numbing cream is usually applied first, so most people find it manageable. You’ll feel pressure and heat during treatment.

How many RF microneedling sessions will I need for acne scars?

Most people need around three sessions, four to six weeks apart. Deeper or more extensive scarring may need more.

Can RF microneedling get rid of acne scars completely?

It can soften and smooth scarring noticeably, but it rarely removes it completely. The aim is a clear improvement in texture and how scars catch the light.

When can I wear makeup after RF microneedling?

Most people can wear makeup the day after treatment.
