If you've ever finished a long fight with breakouts only to be left with dents, shadows and uneven texture, you're not alone. Acne scars are one of the most common reasons clients ask me about microneedling. It's a fair question, and it deserves an honest, research-backed answer. Here's what the studies actually show, which scars respond best, and what a realistic plan looks like at my Henderson studio.
First, what kind of acne scars do you have?
Not all scars are the same, and that matters for results. A widely used dermatology classification sorts atrophic (sunken) acne scars into three main types (Jacob et al., 2001):
Rolling scars: wide, soft, wave-like dips that make skin look uneven in side lighting.
Boxcar scars: round or oval depressions with sharper edges.
Icepick scars: narrow, deep pits that look like tiny punctures.
The same paper describes treatments matched to each scar type, including surgical options such as punch excision and subcision for certain scars (Jacob et al., 2001). Those are medical procedures I don't perform. So part of my job at your consultation is being honest about what microneedling can realistically improve, and when a dermatologist is the better next step.
How microneedling works on scar texture
Microneedling, also called percutaneous collagen induction, creates thousands of controlled micro-channels in the skin. Your skin responds with its natural repair process, which includes building new collagen. For sunken scars, the goal is to gradually soften the edges and improve overall texture. If you want the full step-by-step on the treatment itself, start with my guide to microneedling in Henderson: how it works, how many sessions and what to expect.
What the research shows
Microneedling for acne scars has been studied for years, and the overall picture is encouraging.
Consistent improvement across studies. A systematic review of 33 studies found that every one reported improvement in the appearance of acne scars after microneedling. The authors also noted that evidence was inconsistent when comparing microneedling alone with combination treatments or fractional lasers (Mujahid et al., 2020).
Strong results in randomized trials. A meta-analysis of 12 randomized controlled trials (414 participants) found that microneedling without radiofrequency produced significantly better objective scar improvement than the treatments it was compared with. It was also associated with less post-inflammatory hyperpigmentation, the dark marks that can follow skin trauma (Shen et al., 2022).
Safe across skin tones. In a study of 60 patients covering all skin phototypes (I through VI), three monthly microneedling sessions significantly reduced acne scar severity. Skin surface irregularity dropped by an average of 31%, and no short- or long-term pigment changes were seen in any group (Fabbrocini et al., 2014).
Pairing with peels can do more. A 2025 meta-analysis found that combining microneedling with chemical peels outperformed either treatment alone for atrophic acne scars, with only mild, temporary side effects (Woźna et al., 2025).
That skin-tone finding is a big deal for our diverse Henderson and Las Vegas community. A treatment that has held up well across every skin type in research is worth knowing about.
Microneedling in Henderson for acne scars: what a realistic plan looks like
Here's how I approach acne scar clients in the studio:
Start with a skin assessment. We look at your scar types, skin tone, sensitivity and whether you still have active breakouts. I don't microneedle over active, inflamed acne, so if breakouts are still happening, we calm those down first.
Book one session at a time. I offer microneedling as single sessions, not packages, so you're never locked in. In the research above, studies commonly used a series of sessions spaced about a month apart (Fabbrocini et al., 2014). Scar remodeling is gradual, so plan for a series rather than a one-and-done.
Consider the exosome add-on. Exosomes can be added to any microneedling session. If you're curious what they are and what the research does and doesn't say, read what exosomes in skincare actually are.
Think about peels as a partner. Because the research supports combining microneedling and peels (Woźna et al., 2025), we may talk about building a professional chemical peel into your plan on a separate visit. Each treatment is booked and priced on its own.
Protect your progress. Sun exposure is tough on healing skin, especially in the desert. Daily mineral SPF, like the EltaMD UV Skin Recovery SPF 50 Mineral Sunscreen, is non-negotiable in my aftercare. More picks are in my best mineral sunscreens for the Las Vegas sun.
What microneedling can't do
I'd rather set honest expectations than overpromise. Microneedling improves the look of scars. It doesn't erase them. Deep icepick scars and severely tethered scars may need medical procedures, such as those described in the classification research above, that are performed by a dermatologist or plastic surgeon. I don't offer lasers, radiofrequency microneedling or injectables, and I'll tell you plainly if your scars would be better served elsewhere.
And if what's bothering you is flat brown or red marks rather than true indentations, that's often pigment rather than scarring. A different plan, like targeted serums or peels, may be a better fit. My guides to azelaic acid and dark spot serums are a good place to start.
Why I love microneedling for acne scars
I love that microneedling works with your skin's own repair process, and that it has held up well across skin tones in the research. For clients who've been self-conscious about texture for years, steady, visible softening can make a real difference in how they feel about their skin.
