Can Microneedling Minimize Large Pores? What Dermatologists Say in 2026

Large pores are one of the most searched skincare concerns worldwide — and for good reason. They affect skin smoothness, make-up application, and overall confidence. Microneedling (also called collagen induction therapy, or CIT — a minimally invasive procedure that uses fine, sterilized needles to create controlled micro-injuries in the skin) has emerged as one of the most clinically credible options for addressing them. But does the science actually back it up? Here is what the latest dermatology research says.

What exactly are enlarged pores, and why do they appear?

Enlarged facial pores are a common aesthetic concern that worsens with age due to increased sebum production, reduced skin elasticity, and photoaging. A published study describes enlarged facial pores as a concern influenced by age, genetics, and increased sebaceous activity. In practical terms, a pore is the opening of a hair follicle and its attached sebaceous (oil-producing) gland. When the follicle wall loses structural support — because collagen has thinned — the opening stretches and becomes more visible. The body loses about 1 percent of its collagen per year starting in the mid-20s, and the skin gradually becomes rougher, duller, and less even. That slow structural decline is precisely where microneedling intervenes.

How does microneedling actually shrink the appearance of pores?

Microneedling involves using tiny needles to create controlled micro-injuries on the skin's surface, stimulating the body's natural healing response and boosting collagen and elastin production. The skin's natural wound-healing response is activated, producing and distributing new collagen, plumping up and tightening the appearance of the enlarged pores and effectively making them appear smaller. The key word here is appearance: pores are normal skin openings and cannot be removed or permanently closed; microneedling may make enlarged pores look less noticeable by supporting smoother, firmer-looking skin over time.

On a cellular level, microneedling has been shown to enhance the delivery of topically applied substances by creating microchannels in the skin, which is why many clinicians pair it with serums containing hyaluronic acid, growth factors, or — as cutting-edge research now shows — stem cell-derived exosomes.

What does the clinical research from 2025–2026 actually show?

The evidence base has matured significantly. A study published in the Journal of Clinical and Aesthetic Dermatology found that participants who underwent microneedling treatments experienced significant improvements in skin texture and pore size reduction. More recently, a study published in Plastic and Reconstructive Surgery, Global Open in 2025 evaluated microneedling combined with exosome therapy and reported Global Aesthetic Improvement Scale scores of 4 to 5, indicating "very much improved" outcomes for both pore reduction and skin texture enhancement.

A pivotal 2025 randomized controlled trial published in the Journal of Cosmetic Dermatology compared two delivery methods for pore treatment. The trial was conducted at a referral centre in Iran; thirty patients aged 25–60 years with enlarged facial pores were enrolled and randomized to receive intradermal BoNTA injections on one side of the face and microneedling-assisted BoNTA injections on the other side. Both intradermal and microneedling-assisted BoNTA injections proved effective in treating enlarged facial pores, with no significant difference in efficacy — findings that provide flexibility for dermatologists in selecting the appropriate treatment method based on patient preferences and clinical considerations.

On the broader systematic evidence front, a systematic review conducted in accordance with PRISMA guidelines included 15 randomized controlled trials involving approximately 1,200 participants and found that across multiple conditions, microneedling — particularly when combined with adjunct therapies — demonstrated significant clinical benefits.

A study cited by Liv Hospital found that 93.8 percent of patients saw meaningful pore improvement after four sessions; the collagen produced during each session tightens the tissue around the pore, making it look smaller and less visible over time.

How many sessions do you need, and how far apart should they be?

Realistic expectations are everything. A typical clinical plan involves 3 to 6 sessions, usually spaced about 4 weeks apart. Results are gradual — most people begin to see noticeable improvement after the 2nd or 3rd session, with continued progress over the following months as collagen remodeling takes place. Maintenance treatments every 6 to 12 months help sustain the improvement.

A practitioner may adjust the series for pore visibility, sensitivity, healing, and other concerns, so there is no universal prescription — individual skin type, sebum levels, and lifestyle all play a role.

Is at-home microneedling worth it for large pores?

Professional in-clinic treatments remain the gold standard for meaningful pore reduction, but at-home devices have improved considerably and can serve a complementary role. The at-home microneedling market has exploded with derma rollers, microneedling pens, and stamp devices available for consumer purchase — the appeal being that professional microneedling is expensive and requires appointments, while an at-home device promises similar results for a fraction of the cost and on your own schedule.

For those who want to maintain results between clinic visits or dip their toes into CIT for the first time, the SKINDELÚX Microneedling Pen is a precision at-home option designed with adjustable needle depth so you can tailor intensity to your skin's tolerance. As with any at-home device, it is important to follow a sterile protocol, use appropriate needle lengths (0.25–0.5 mm for surface texture), and always apply a broad-spectrum SPF the morning after treatment.

That said, at-home rollers are unlikely to produce meaningful results for enlarged pores on the level that professional, clinic-grade devices achieve, so manage expectations accordingly and treat at-home use as a supportive — not replacement — tool.

Are there any real risks or side effects to know about?

Microneedling is generally well tolerated, but it is not risk-free. Aggressive or improperly performed microneedling at excessive depths or with contaminated tools can cause scarring or textural damage that makes pores look worse. Poor aftercare — applying irritating products, picking at peeling skin, or not protecting against UV exposure — can trigger post-inflammatory hyperpigmentation or prolonged inflammation that affects skin texture around pores.

Adding a controlled injury on top of existing skin inflammation is not therapeutic — it is provocative. This is why dermatologists consistently advise against microneedling on actively inflamed, infected, or sunburned skin. With minimal downtime and benefits for many skin types, it continues to be a popular option for patients looking to improve overall skin texture and quality without surgery — as long as it is performed correctly.

What is the emerging frontier in pore treatment — beyond standard microneedling?

The most exciting development is the combination of microneedling with stem cell-derived exosomes (exosomes — tiny nano-sized vesicles secreted by cells that carry regenerative growth factors and signaling proteins). Microneedling combined with stem cell-derived exosome therapy seems to be a safe and effective treatment for facial pore reduction and skin texture enhancement. A 2025 case study demonstrated 21-month sustained outcomes in pore size, erythema, and hyperpigmentation using exosome-based therapy, published in Dermatology and Therapy.

However, researchers urge caution: the small sample sizes and lack of control groups in current exosome studies limit generalizability, and these results should be seen as a foundation for future research rather than definitive evidence — larger randomized controlled trials with objective measurements are needed to confirm efficacy and long-term outcomes.

The bottom line: what should you realistically expect?

Microneedling can help reduce the appearance of acne scars, minimize enlarged pores, and soften fine lines and wrinkles by stimulating the skin's natural collagen production process. The clinical record as of 2026 is genuinely promising — but it demands realistic framing. Pores cannot be erased; their appearance can be meaningfully reduced with a consistent, properly spaced treatment plan, good aftercare, and the right adjunct therapies. Consistent treatments and a personalized approach can deliver noticeable, long-term improvements.

Frequently Asked Questions

Can microneedling permanently close my pores?
No. Pores are permanent anatomical structures that cannot be closed or removed. Microneedling works by stimulating collagen production to tighten the surrounding tissue, which reduces the visual appearance of pore size — it does not eliminate pores altogether.
How many microneedling sessions are needed to see results on large pores?
Most clinical protocols recommend 3 to 6 sessions spaced approximately 4 weeks apart. Visible improvement typically begins after the 2nd or 3rd session, with continued collagen remodeling for several months afterward. Maintenance sessions every 6–12 months help preserve results.
What needle depth is best for targeting enlarged pores?
For pore refinement and superficial skin texture, professional providers typically use needle depths of 0.5–1.5 mm depending on skin thickness and area. At-home devices should be used at shallower depths (0.25–0.5 mm) to minimize risk of irritation or damage.
Is microneedling safe for all skin types, including darker skin tones?
Microneedling is generally considered safe across all Fitzpatrick skin types because it generates no heat, significantly reducing the risk of post-inflammatory hyperpigmentation compared to ablative lasers. However, a consultation with a dermatologist familiar with your skin type is always recommended before treatment.
What makes microneedling with exosomes different from standard microneedling?
Exosomes are nano-vesicles derived from stem cells that carry regenerative growth factors. When applied immediately after microneedling, the microchannels created by the needles allow deeper penetration of these exosomes, potentially amplifying collagen synthesis and skin renewal. A 2025 study reported sustained pore improvement at 21 months with this combination — though larger trials are still needed.
What should I avoid immediately after a microneedling treatment?
For at least 24–72 hours post-treatment, avoid vigorous exercise (sweat can irritate open microchannels), direct sun exposure without SPF, active ingredients like retinol or AHAs, and any picking at peeling skin. Poor aftercare is one of the leading causes of suboptimal results and unwanted side effects.
