On the face, this is where the evidence is strongest, but not for every scar.
The scar type decides. Which one responds, and for which the home needle isn't the answer.
- 11 studies pooled, 713 people (meta-analysis).
- They looked at microneedling itself, measured with a medical scar scale.
Evidence level · ACNE SCARS
A Proven
What this grade means: Multiple rigorous randomized trials (RCTs), or a pooled analysis of these (meta-analysis), measure microneedling itself, on a medical scale. The grade describes the level of evidence, not what will happen for you.
This page stands at grade A.
These studies are about microneedling itself, typically with a clinical device (pen, roller, RF device), we have no study of our own.
The honest balance, what it actually measures
Meaningful improvement is this much more likely than with chemical exfoliation (peeling). Chance doesn't explain this (p<0.0001).
PMID 42281674 · 4 studies pooled, 264 people (meta-analysis) · with a clinical device (pen, roller)In the odds of significant (at least 50%) improvement, there's no difference compared to peeling, it's a tie here.
same pooled analysis · 5 studies, 215 peopleThe deep, needle-width channel doesn't fill in with needling. Rolling and boxcar scars are the territory.
this isn't statistics, it's anatomy, your scar type decidesWhat we DON'T know / what wasn't measured
There's no guaranteed percentage: the type and depth of your scar decides, not the average.
There's no study done with a home hand-held device, the direction of the effect is the same, the magnitude is expected to be smaller.
The weak point in this evidence
The meta-analysis compares against chemical peeling, not against doing nothing. So the number says: microneedling is at least as good as an established treatment. It does NOT say "1.79 times better than doing nothing."
My own acne scars
The photo is of my own face, from personal use. I also used a skincare routine alongside it, so I can't isolate what microneedling alone contributed. My scars became shallower, but didn't disappear, and your results may vary.
What it helps with, and what it doesn't
Rolling + boxcar scars: microneedling's territory.
Icepick scars: they don't fill in, we point you elsewhere.
Active, inflamed acne: contraindicated, don't stamp over it.
Only start if you can take sun protection seriously. Because of the fresh micro-channels, the skin is temporarily more sun-sensitive: no direct sun or tanning beds for 24 hours after treatment, and after that, daily high-factor (at least SPF 30) sunscreen, especially in the days following treatment. UV breaks down collagen and can cause discoloration, so without sun protection, UV can undo what the needling started.
Not every acne scar is the same
Rolling and boxcar scars fill in with collagen induction. The deep icepick channel doesn't.
More details
For icepick scars, TCA CROSS or a clinical procedure is more effective. If you don't know which type you have, ask for an expert opinion.
Will it scar my skin?
The needle makes many tiny, separate punctures: intact skin remains between them, and regeneration starts from there, which lets it heal without scarring. Linear, "tram-track"-like scars come from sideways movement (dragging), and the stamp rules exactly that out: one press down, one lift up, no dragging.
More details
The dermaroller inherently drags: it rotates, entering and exiting at an angle, which causes the "tram-track scar." The motorized pen is a vertical device, but it runs continuously: if you drag it across the skin instead of lifting it between two points, a linear mark can form there too. That's a user error, but an easy one to make. The manual stamp works without a motor or rotation, at a fixed 1 mm, with a single motion: there's nothing to get wrong in the movement. That's why, for home use in inexperienced hands, this is the most controllable, hardest-to-mess-up form, you're in charge the whole time. The remaining risk is excessive pressure (especially over bony areas), so don't force it in, and don't go above 1 mm.
Compared against an established treatment
Microneedling made improvement ~79% more likely than chemical peeling (RR 1.79). PMID 42281674 So the comparison is against an established treatment, not against doing nothing.
More details
In the odds of significant, ≥50% improvement, though, there's no difference between the two (RR 0.97; p=0.74). Microneedling is at least as good as peeling, and more likely to give at least some improvement, but it's not a miracle cure.
PMID 42281674 · systematic review + meta-analysis, 11 studies, 713 participants.
How it fills in the scarThe skin cross-section: the scar rebuilds from below
The needle targets the scarred dermis, right where the collagen is missing. Wound healing fills the crater from below, it doesn't cover it over from above.
How to use it, the full protocolNeedle depth, how many sessions, what to apply afterward
Our device is a fixed 1.0 mm. In the literature, deeper scars are often treated at 1.5 mm, but with a clinical device. You can NOT go "deeper" by pressing harder: that only causes injury.
Every 4–6 weeks, min. 3–6 sessions
Minimal formulas. No active ingredients on the day of treatment: no vitamin C, no peptides, no acids. Whatever you put on can get in through the micro-channels.
acids for 21 days · retinol for 5–7 days (our own caution recommendation) · active acne: never
Frequently asked questions
How many sessions do I need?
Minimum 3–6 sessions, every 4–6 weeks. No results are expected after 1–2 sessions, building collagen takes time. If there's nothing after 3, the protocol (depth, scar type) needs adjusting.
Is this the same as a clinical treatment?
Not the same. According to the evidence, microneedling is comparable to chemical peeling, laser may offer more for deeper scars.
Can I use it on active acne?
No. Stamping on active acne is forbidden, it can cause pigmentation spots and infection. Address the active acne first, and only treat the settled, scarred area.
Who it's NOT for
Keloid tendency or abnormal scarring: NEVER. If you've ever grown a keloid scar, microneedling stimulates exactly the collagen formation that's overactive in you. It's a contraindication in the instructions for use as well, and this is the group where it can do the most harm.
Severe, inflamed acne: contraindicated overall, not just on the affected spots. The needle carries the bacteria deeper and into neighboring follicles. Address the inflammation first, with a dermatologist, there's time for the scars later.
The full list of contraindications
Don't use this device if: you're under 18 · there's an open wound, abrasion, burn, or fresh scar in the area · you have active skin inflammation, eczema, psoriasis, or a fungal or bacterial infection there · you have severe acne, or a tendency to keloids / abnormal scarring · you have rosacea · you have uncontrolled diabetes · you have a blood clotting disorder or take blood thinners · you have active cancer, or are undergoing chemotherapy or radiation therapy · you have HIV/AIDS, hepatitis, or another serious systemic infection · you're pregnant / breastfeeding (only with medical consultation) · you're allergic to the disinfectant or to the cosmetic product you intend to use.
And never use it on the eyelids, the thin skin around the eyes, mucous membranes, lips, or body openings.
What do the studies referenced here prove, and what do they NOT prove?
Important: these studies support microneedling as a method, typically with a clinical device (roller, motorized pen, radiofrequency device), under medical supervision. No study has been done with our device, and we don't have a study of our own. We bring the mechanism home, as safely as possible: many good effects are possible, but we can't guarantee anything.
The older a scar is, the harder it is to shift: the connective tissue matures over time and becomes more stubborn. Old scars aren't hopeless either, but time isn't working for you. If you have active acne, address that first, order and patience.
Today you're in a better position than you'll be tomorrow.

Dermastamp (1 mm)
EU-registered It's on the market as a medical device (EU-MDR 2017/745, Class I), and it's listed in EUDAMED, the EU's official database: UDI-DI 06976567878014. As the importer, I'm registered too: HU-IM-000051605. This is traceability, not approval: being registered doesn't mean anyone has confirmed that it works. , Single-use One stamp equals one treatment: according to the manufacturer's instructions, it can't be cleaned or reused after use (registered under EU-MDR Class I). You start every treatment with a new device, factory-treated with an electron beam and disinfected by you before use. This is the most hygienic way to do microneedling at home. microneedling device with detailed instructions for use; How long does one package last? The calculation for the four single-use stamps is based on 1 use per week on the scalp, or 1 use every two weeks on the face. You use a new, unopened stamp for every treatment: no reuse, no carried-over contamination. The 1-pack variant is enough for one treatment.
We currently ship within the European Union only.
So you cannot order this product right now, and prices are shown in Hungarian forint.

I'm training to be a cosmetologist, and I found microneedling because of my own hair loss and skin problems. I want to bring this mechanism home as safely as possible, for you too. I stamp my own scalp weekly, and my face every 2–3 weeks.

Edit✓ verified buyer2026. 07. 24.
The parcel arrived on the third working day after my weekend order 😊 The product matches the description, using it is practically painless, afterwards there is a mild burning feeling and redness. I can report on the effect later, I trust that I have reason to hope. Before use I disinfected not only the stamp but the skin as well, with a spray made specifically for this. I found a face mask as a gift in the parcel, I am really glad about it, thank you!
Special thanks for the detailed description :)
Wishing you much success, kind regards: Edit -

Everything arrived fine. I had my doubts that the site was a scam, but no. I got what was promised. After a 0.5 mm CIT pen (which was quite good, but is not available anymore) and cosmetic mesotherapy (which is expensive, and my skin protested against it so much after the 4th time that I stopped), I am now waiting for this treatment with curiosity. Thank you for the work you put into it!

What to expect?
Does it hurt? What to expect the first time?
Personal experience
Not pleasant, but in my own experience, clearly bearable. On the image I marked how sensitive I found each zone:
- Green: easiest. Forehead, most of the face.
- Yellow: noticeable, but comfortable. Around the eyebrows, nose bridge, jaw.
- Red: more sensitive, but short-lived. Nose, under-eye area, around the mouth. Don't stamp near the eyelid or inner corner of the eye.
In my experience the scalp is less sensitive than the face. The first session feels the most unfamiliar, but based on customer feedback, most people expect it to be worse than it is.
How long does your skin stay red?
In my experience the redness on the face fades within a few hours, with little trace left by the next morning. In more sensitive zones (nose, around the mouth) it can take a bit longer. On the scalp it's less visible, mostly covered by hair, and settles faster.
Don't wear makeup the next day. Sun protection is required.
What's allowed and what isn't after stamping? →Personal experience, not a clinical study result. Individual reactions may vary.
What shouldn't you use it for?
Don't use it on irritated, sunburned, actively inflamed, or infected skin. Not recommended for open wounds, active acne, eczema, or psoriasis-affected areas. If you take blood thinners or are under dermatological treatment, check with your doctor.
You'll find the full list of contraindications in the instructions for use that comes with every package. You can review the full risk picture here: Before you buy.
How do you know it's enough? How hard should you press?
It's not about force. Work with vertical, precise motions: straight in, straight out. Go over each area several times to cover the whole zone evenly. The device's 1 mm needle length helps you avoid going deeper than needed.
The goal is even coverage and controlled technique, not force.
When will I get it, and how do I pay?
Cash on delivery too: you pay when the package is in your hands, not in advance. Card payment is also available. Delivery 990 Ft, to a Foxpost parcel locker.
Why is this device different?
Needle material
80 GOLD-PLATED STEEL NEEDLES
Medical-grade 304 stainless steel, with a real gold coating, the same base material used in surgical instruments. According to independent lab tests (TÜV SÜD, SGS) and the biocompatibility tests mandatory for skin-contact medical devices (EN ISO 10993-1, -5, -10), every value for the needle came in below the limit, and it passed TÜV's heavy-metal migration test (21 metals, including nickel release). Regardless, if you have a known metal allergy, consult a doctor, known allergy is a contraindication according to the instructions for use.
1 treatment = 1 stamp, for maximum hygiene
Needle layout
I tried every model, so you don't have to
I tested dozens of microneedling devices, different needle densities, layouts, and depths. The stamp head with 80 needles arranged in an even grid gave the most uniform micro-channels.
Marci · I've been doing microneedling on my own skin for 4 years
Hygiene
Electron-beam treated (e-beam)
It undergoes electron-beam treatment during manufacturing. It's not a sterile device, disinfect it before each single use, according to the instructions. It keeps its factory cleanliness until the packaging is opened.
Factory e-beam treated, single-use
*If you have a strong metal allergy, it's worth testing the stamp with a few punctures on a small area of skin (e.g. the inner forearm) before first use, and observing the reaction for 48 hours.
- The E-BEAM (electron beam) treatment is a quality-assurance/hygiene boost during manufacturing: the packaged product is briefly exposed to an electron beam.
- This is not a "sterility promise," and the Dermastamp is not marketed as a sterile medical device.
- While still sealed, the product gets an extra, documented hygiene step.
- After opening, the home environment varies, which is why the manufacturer specifies: 1 treatment = 1 Dermastamp. This is the device's declared method of use.
This approach brings it closer to a clinical protocol: a predictable device + consistent hygiene.
