Microneedling for Acne Scars: Results, Sessions and a Real Before and After

After nine years of acne, I was left with boxcar and rolling scars, plus dark marks that no cream would shift. I had four microneedling treatments over five months, and the photos in this article are my own skin, before, during and after.

Short answer: yes, microneedling works for acne scars, but only certain kinds. It worked for mine. It is one of the best-supported treatments for depressed scars like rolling and boxcar, it does less for deep icepick scars, and it is the wrong treatment for raised scars. Most people need 3 to 6 sessions, and the results keep building for months.

Below is my full session-by-session log with what each one cost, including the add-on that made my scars worse, and what the research says about why some of it worked and some of it didn’t.

Does Microneedling Work For Acne Scars?

It did for me. After four sessions my scars are barely visible and the discoloration is minimal. My texture still is not perfectly smooth, but the difference is obvious in the photos.

The reason it works: acne scars form where inflammation destroyed collagen, leaving a dip in the skin. Microneedling makes thousands of tiny controlled injuries, and as the skin repairs them it lays down new collagen that gradually lifts those dips. The research backs up what I saw:

• A 2022 meta-analysis of 12 randomized trials and 414 patients found that microneedling without radiofrequency gave significantly better scar improvement than the treatments it was compared with. It also caused less post-inflammatory hyperpigmentation, the dark marks that can follow a treatment, and no study reported infection or new scarring (Shen et al., Aesthetic Plastic Surgery).
• A 2021 systematic review of 9 randomized trials concluded that microneedling works for atrophic acne scars on its own or combined with other treatments, with no serious side effects reported (Sitohang et al., International Wound Journal).
• The FDA has cleared microneedling devices to improve the appearance of facial acne scars in adults 22 and older (FDA).

What it will not do is erase scars completely. Mine got shallower and far less noticeable, not gone. The American Academy of Dermatology also notes that results fade gradually as your body loses collagen with age, and that a dermatologist may recommend a maintenance session once a year.

Which Acne Scars Respond (And Which Don’t)

My scars were boxcar and rolling, which turned out to be the two types that respond best. That is probably the biggest reason my results were good. In one clinical study that measured results by scar type, rolling and boxcar scars showed good to very good improvement after three months, icepick scars only moderate improvement, and many deep scars responded poorly (El-Domyati et al., 2015).

Scar type	What it looks like	Microneedling	What else is used
Rolling	Wide, soft, wave-like dips	Good response	Often combined with subcision or fillers
Boxcar	Round or oval dips with sharp edges	Good response	Fractional laser, chemical peels
Icepick	Narrow, deep pinpoint holes	Moderate	Acne scar surgery, sometimes combined with microneedling
Deep atrophic	Wide and deep	Poor on its own	Combination treatment planned by a dermatologist
Raised (hypertrophic, keloid)	Bumps above the skin	Not a microneedling treatment	Steroid injections, lasers, other procedures

That last row matters. Raised scars form because the body made too much collagen, so stimulating more only makes them worse. The AAD lists laser treatment and corticosteroid injections among the options for raised scars instead (AAD acne scar treatment). Knowing my scar types going in made the whole plan make sense, and I would not start without knowing yours. It decides everything that follows.

How Many Microneedling Sessions For Acne Scars?

I had four. My scars were not very deep, so my dermatologist recommended stopping there. Most people need 3 to 6 sessions, with shallower scars at the low end and deeper scars at the high end, and clinics usually space them 4 to 6 weeks apart so the skin can finish rebuilding in between. Looking back, I suspect one of my PRP sessions went badly because I didn’t give my skin enough time to heal first.

The part I underestimated was how long the results take. My biggest change showed up about six months after my last session. The research shows the same slow curve. In the El-Domyati study, patients had six sessions two weeks apart:

Point in treatment	Improvement in scar appearance	Patient satisfaction
After 1 month (2 sessions)	15 to 20% (mild)	30 to 40%
After 3 months (6 sessions)	51 to 60% (good)	80 to 85%

That was a small study of 10 people, so treat the percentages as a guide rather than a promise. The shape is the useful part: early change is modest, and most of the improvement arrives months later. The AAD says the same, that full results usually take several months because the collagen keeps rebuilding after your skin looks healed. If you are judging your results a week after a session, you are judging too early.

What Depth Is Used For Acne Scars?

My dermatologist handled the depth, which is how it should be for scars. Clinics treat acne scars with needle lengths of roughly 0.5mm to 2mm, going deeper for deeper scars and pockmarks (Cleveland Clinic). The depth changes across the face, since skin over the cheeks is thicker than skin near the eyes or over bone.

Those depths are clinic work. At-home devices are built for shallow depths, and the AAD warns that home microneedling gives less noticeable results and can cause infection, scarring or color changes when misused. For scars, home needling is the wrong tool. The microneedling depth chart covers the full range by concern and face area.

My Microneedling Acne Scars Before And After: Session By Session

This is exactly what I had done, what it cost, and what happened after each session. It is one person’s experience, not medical advice, but it shows how the process really goes, including what did not work.

Before microneedling, I finished a three-month course of Accutane and tried collagen-boosting and anti-pigment products, with little change. That is when my dermatologist recommended microneedling. Along with the boxcar and rolling scars, I had some hyperpigmentation that showed up as red, purple and dark marks.

Session 1: Microneedling ($230)

My dermatologist applied numbing cream and microneedled my skin for about 15 minutes. I felt no pain. Afterward I got a soothing hyaluronic acid cream and light therapy to calm the inflammation. A brown, sunburn-like patch appeared, which is not very common, and it went away after 72 hours. I skipped makeup and wore sunscreen the whole time, as my dermatologist told me to.

Result: a noticeable reduction in both the indentations and the dark marks after one session. I was happy enough that I tried microneedling with PRP four weeks later.

Session 2: Microneedling With PRP ($650)

I gave blood before the procedure, since I was told that combining the two boosts collagen more. My dermatologist applied the platelet-rich plasma to my scars and microneedled for about 10 minutes, followed by light therapy. The redness took 72 hours to clear.

Result: disappointing. It did not make anything worse, but I saw no real improvement.

Session 3: Microneedling With PRP Again ($650)

Two months later I gave PRP another try, applied both before and after needling. Redness and some inflammation took two to three days to settle.

Result: this one made my scars more visible. My dermatologist concluded PRP did not suit my skin and switched me to microneedling combined with a fractional laser.

Session 4: Microneedling With Fractional CO2 Laser ($1,500)

My dermatologist combined microneedling with a fractional CO2 laser, and discounted it because of my earlier results. My face felt very hot afterward, and the redness and inflammation took a week to subside.

Result: this worked extremely well, for both the scars and the dark spots. It took about six months for the full change to show. I also started azelaic acid for three months afterward.

Where I Ended Up

I spent about $3,030 on four sessions, in a small town in the Midwest where prices are lower than in a big city. My texture still is not as smooth as I would like, but the scars are barely visible and the discoloration is minimal. I am very happy with the result, and I did not have to step away from my daily life for long to get it.

On downtime: people say microneedling has none, but I needed about 72 hours after each session before my skin looked normal, with a sunburn feeling and tightness for the first day. My hairline, jawline, upper lip and forehead were more sensitive than the rest of my face.

Microneedling vs Laser vs PRP vs RF For Acne Scars

My experience lines up with the research in a way I did not expect: the plain treatment beat the expensive add-on, and my biggest jump came from combining two methods under my dermatologist’s plan.

Treatment	What the evidence says	Worth knowing
Microneedling	Best scar improvement in the 2022 meta-analysis; less post-inflammatory darkening than comparators	Low downtime. Cleveland Clinic calls it ideal for darker skin tones because it does not carry the discoloration risk of heat, light and laser treatments
Fractional laser	The AAD lists laser resurfacing as a standard acne scar treatment	More downtime and more discoloration risk on darker skin. Combined with microneedling, it was my most effective session
RF microneedling	No significant advantage over comparators in the 2022 meta-analysis	Costs about double. The AAD says it is safe for all skin tones based on small studies; the FDA has issued a safety communication on certain uses
PRP add-on	Commonly offered for acne scars; whether it adds enough to justify the price is still debated	Adds several hundred dollars a session. It did not help me, and one session made my scars more visible
Fillers	The AAD says they add volume to depressed scars	Temporary, about 3 months to 2 years, and need touch-ups

If your scars are rolling or boxcar like mine, plain microneedling is the sensible place to start, and it is the one the research supports best. I would want any add-on justified for my specific scars rather than sold to me as an upgrade. More on each: microneedling with PRP and RF microneedling.

How Much Does Microneedling For Acne Scars Cost?

My four sessions came to about $3,030, and almost all of that was the three sessions with PRP or laser added. My plain microneedling session was $230.

At clinics that publish prices, standard microneedling costs $200 to $699 a session, with a median of $350, and RF runs about double. A course of 3 to 6 plain sessions comes to roughly $1,050 to $2,100 at the median price. The microneedling cost guide has the published prices from 14 clinics and what to ask before you pay. To find a clinic, the city rankings for NYC, Tampa, Miami, Atlanta and San Diego list the top 10 providers by thousands of Google reviews.

Side Effects, Downtime And Skin Tone

Expect swelling and mild pain for the first day, then redness for a day or two. I needed closer to 72 hours per session, and a week after the laser combination. In the El-Domyati study, swelling and discomfort resolved within 24 hours, redness within one to two days, and patients were back to normal activity on day two. The FDA lists bleeding, bruising, redness, itching and peeling as common and short-lived, with dark or light spots, cold sore flare-ups and infection as less common risks.

Skin tone is where microneedling stands out for scars. Heat- and light-based treatments carry a higher risk of darkening or lightening the skin, which matters most for darker skin tones. The 2022 meta-analysis found microneedling caused less post-inflammatory hyperpigmentation than the treatments it was compared with.

What I Would Tell Anyone Starting Out

• Get your scar type diagnosed first. Mine were boxcar and rolling, which is why microneedling suited me. It decides whether it is the right treatment for you at all.
• Tell your dermatologist about every acne treatment from the last two years. I had just finished Accutane. The AAD advises this because starting some scar treatments during, or soon after, certain acne medications can cause unwanted side effects.
• Get active breakouts under control first. Scar treatment works best once new acne has stopped forming.
• Give your skin time between sessions. I think rushing is part of why my PRP sessions went badly.
• Ask for the full course price and how many sessions they expect for your scars.
• Choose a trained provider. The FDA recommends a provider specially trained in microneedling. Scar work at clinical depths is not something to do at home.

Aftercare matters too. My dermatologist applied a hyaluronic acid cream after my first session, and I skipped makeup and wore sunscreen every day. For home, a pure hyaluronic acid serum keeps healing skin hydrated. A mineral sunscreen such as EltaMD UV SPF 46 protects healing skin from the dark marks sun exposure can cause.

FAQ

How many microneedling sessions do you need for acne scars?

Most people need 3 to 6 sessions, spaced about 4 to 6 weeks apart. Shallow rolling scars sit at the low end and deeper scars at the high end. I needed four. Full results take several months to appear.

Does microneedling get rid of acne scars permanently?

It makes depressed scars shallower and less visible, but it does not erase them, and results fade slowly as you lose collagen with age. The AAD says a dermatologist may recommend one maintenance session a year.

Which acne scars does microneedling work best on?

Rolling and boxcar scars respond best. Icepick scars improve only moderately, many deep scars respond poorly on their own, and raised scars should not be treated with microneedling at all.

Is microneedling or laser better for acne scars?

For most depressed scars, microneedling is the better place to start. A 2022 meta-analysis found it gave better scar improvement and less post-inflammatory darkening than the treatments it was compared with, and it carries less discoloration risk on darker skin. Lasers are a strong option too, and combining the two worked best for my stubborn scars.

What depth is used for acne scars?

Clinics use roughly 0.5mm to 2mm, going deeper for deeper scars. Those are professional depths. At-home devices work far shallower and are not the right tool for scars.

Does PRP make microneedling better for acne scars?

Not reliably. PRP adds several hundred dollars a session, and whether it improves acne scar results enough to justify that is still debated. It did not help me, and one of my PRP sessions made my scars more visible.

How long until you see results from microneedling acne scars?

Some change shows within a few weeks, but most of the improvement arrives months later. In one study, scar appearance improved 15 to 20% after one month and 51 to 60% after three months of treatment. My own biggest change showed about six months after my last session.

Is microneedling safe for acne scars on dark skin?

It is one of the better options. Cleveland Clinic notes that microneedling does not carry the discoloration risk of heat, light and laser treatments, and a 2022 meta-analysis found it caused less post-inflammatory hyperpigmentation than comparable treatments.

Summary

• Microneedling is well supported for depressed acne scars, especially rolling and boxcar, the types I had.
• Icepick scars improve moderately; raised scars need a different treatment entirely.
• Plan on 3 to 6 sessions, 4 to 6 weeks apart. Most of the result arrives months later.
• Clinics use about 0.5mm to 2mm. Home devices are not for scars.
• Plain microneedling has the best evidence. PRP did not help me, and RF has no clear edge in the research.
• A course typically costs $1,050 to $2,100 at the median clinic price. Mine was $3,030 with add-ons.
