How Often Should You Get Microneedling, and How Many Sessions?

The short answer

How often should you get microneedling? During a course, once every four to six weeks; after the course, once every six to twelve months to keep the result. The number of sessions in the course depends on what you are treating: three to four for dullness, rough texture and fine lines, six or more for acne scars, and the longest course of all for stretch marks. Going more often does not speed anything up, because the change you are paying for is new collagen, and the skin builds it over weeks, not days. That is also why the best time to judge a course is months after the last session, not the morning after it.

• 3 to 8 weeksthe gap between professional sessions given by Cleveland Clinic, which adds that results can take three to six months to show.
• 6 monthswhen acne scars had improved significantly in a randomised trial of three needling sessions; at three months the change had not yet reached significance.
• 48.9%improvement in newer, red stretch marks six months after a course of four monthly sessions, up from 43.9% at three months, in a 2026 study.

Why sessions are spaced weeks apart

Each session makes a dense pattern of tiny channels in the skin. Those channels close over within about a day, but the useful part, the repair underneath, carries on for much longer: the collagen remodelling that changes a scar happens over roughly four to twelve weeks. A second session booked before that work has moved on mostly re-injures skin that is still busy, which adds redness and irritation without adding results.

So a course is a series of rounds. One session starts a wave of repair, the next session is timed to build on it, and the gains stack up. That is the reason a single treatment tells you very little, and the reason the result keeps improving after the last appointment. Our microneedling page explains the treatment itself, and the aftercare guide covers what to do in the days between.

What a course looks like over a year

Each dot is a session, planned five weeks apart, the middle of the four-to-six-week range. The pale band is the window in which to judge the result: three to six months after the last session.

How many sessions you need, by concern

The concern sets the course, not the area. Two people treating the same face can need very different numbers of visits.

Dullness and rough texture

This is the quickest change to see and the shortest course. Skin often looks brighter within the first week after a session, which is surface recovery rather than the real result, and most people treating dullness or mild roughness are finished in about three sessions. If enlarged pores are part of the picture, our guide on how to shrink pores explains which causes microneedling helps and which it does not.

Fine lines

Crepey texture around the eyes and mouth usually responds within three to four sessions. Microneedling firms the skin rather than relaxing the muscle beneath it, so it softens the texture of a line but will not erase a deep expression line. Microneedling for wrinkles goes into which lines it suits.

Acne scars

Plan for six or more sessions. Rolling and boxcar scars sit deeper, so each round of repair has more to do, and the improvement keeps building for months after the course ends. In the trial behind our second stat card, scars were measurably better at six months, after only three sessions. Our microneedling for acne scars page covers the scar types that respond, and our acne scar treatment guide compares it with the alternatives.

Stretch marks

These need the longest course, and newer marks do better than old ones. In a 2026 study of 29 people, red marks that were still forming improved more than silvery, mature ones after the same four monthly sessions, and both kept improving between three and six months after the last treatment. Body areas take longer and are priced at the clinic; see microneedling for stretch marks.

Active breakouts

Standard microneedling waits until breakouts have settled, because needling across active spots can spread bacteria. Bio microneedling is the needle-free option for skin that is breaking out now, offered at eight Ontario clinics.

What the research schedules looked like

Published studies are useful here because they record exactly how often people were treated. They do not agree on one interval, which is honest information in itself: protocols range from every two weeks to once a month, and every one of them used a series rather than a single session.

Two patterns run through all four. The result was measured weeks or months after the last session, and it was still growing when it was measured. And nobody was treated more often than every two weeks. Clinics generally space sessions further apart than these trials, at four to six weeks, so that each round of collagen building has time to move on before the next one starts.

Can you have microneedling too often?

Yes. The American Academy of Dermatology warns that overusing microneedling can irritate the skin, which is the opposite of what most people book it for. A 2021 review of 51 studies covering 1,029 patients found the usual side effects were the expected ones: redness, pain, swelling and short-lived irritation. Keeping enough time between sessions is a large part of keeping it that way.

Three signs mean the next session should wait: skin that is still red, flaking or sensitive from the last one; active breakouts in the area; or a cold sore or other skin infection. If you are using a home roller between clinic visits, read our guide to at-home microneedling first, because layering the two is one of the easiest ways to overdo it.

Plan your course

What a course costs at Femme

Microneedling is $199 a session, or $499 for a package of three, and $225 a session, or $597 for three, with the neck included. The price is the same at all twelve clinics. Because the course length is set by the concern, the useful number is the price of the course you need, not the price of one visit.

Our microneedling cost guide compares these prices with other Canadian clinics, every treatment is listed on the pricing page, and is microneedling worth it? sets out which concerns justify a full course. If you are also planning laser, how many laser hair removal sessions you need works the same way: a course sized to the goal, not a single visit.
