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 measured microneedling as a method. The studies were done with dermarollers and clinical devices.
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 responds the least, improving only slightly even with a longer, clinical needle. Rolling and boxcar scars are the territory.
anatomy: your scar type decidesWhat we DON'T know / what wasn't measured
How much your scar improves is decided by its type and depth, so nobody can give you a percentage in advance.
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.
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 microchannels, the skin is temporarily more sun-sensitive: no direct sun or tanning beds for 24 hours after treatment, and from the next morning, SPF 50 sunscreen every morning. UV breaks down collagen and can cause discolouration, 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. Press down gently, especially over bony areas. The depth comes from the fixed 1 mm needle.
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 is more likely to give at least some improvement.
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 protocolStep by step, from preparation to disposal
One session every 2–3 weeks, in the evening, for at least 4–6 treatments. On the same area, no sooner than two weeks later, always with a new stamp.
Wash your hands with soap. Wash your face with a gentle foaming cleanser; micellar water isn't enough here. Start without makeup, on completely dry skin.
Open it right before use, and don't touch the needles. Rinse the needle head with warm water, then disinfect it with 70% or stronger alcohol for 60–120 seconds. Wait until it is completely dry.
Divide the area into smaller sections. Place the stamp perpendicular to the skin, press down gently, and lift. You don't drag it, you just press. 4–6 times per section, each time a little further along. Mild redness and tiny pinpoint bleeding are normal.
Don't rub it or wash it off, let it dry on its own. Don't put anything on it that day.
Foaming cleanser, Centella serum, moisturiser, and finally SPF 50. From this day on, you need sunscreen every morning.
For 24 hours: makeup, swimming pools, saunas, tanning beds and strong sun. Retinoid and vitamin C: the user guide says 24 hours for retinoids, I wait 48 hours to be on the safe side. Acid exfoliants (AHA/BHA): at least one week, a published review recommends this. Every skin is different, find out what works for you.
Never on active acne, broken or inflamed skin.
One stamp, one session. Put it back in its case and throw it away, closed, with your household waste.
Fixed 1.0 mm. It can't be adjusted, so you can't accidentally go deeper.
Frequently asked questions
How many sessions do I need?
At least 4–6 sessions, every 2–3 weeks. Collagen builds slowly, so don't expect visible change after 1–2 sessions. If you see no change after 4–6 sessions, check your scar type: the icepick scar responds the least, improving only slightly even with a longer, clinical needle. That calls for TCA CROSS or a clinical procedure.
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.
Which devices were the studies cited here carried out with?
These studies measured microneedling as a method, with clinical devices (roller, motorized pen, radiofrequency device), under medical supervision. I refer to them. My aim is to bring this mechanism home as safely as possible, because many good effects are possible.
Today you're in a better position than you'll be tomorrow.

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.

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 else do I need to buy?
- 170% alcohol: for disinfecting the stampBefore stamping, the stamp needs to soak in alcohol. The instructions for use name 70% isopropyl alcohol (IPA), and the steps call for a 70% or stronger alcohol-based disinfectant. 70% ethyl alcohol is such a disinfectant too. According to the disinfection guidance of the US Centers for Disease Control and Prevention (CDC), ethyl alcohol acts on a broader range of viruses, while isopropyl was slightly stronger on two tested bacteria (E. coli, S. aureus). I also show the process on video, in the "Usage on video" section, and I detail it in the instructions in the box.
- 2SPF 50 sunscreen: if you use it on your faceStamped skin is more sensitive to UV radiation, so you need SPF 50 every morning, starting the morning after.
- 3Gentle cleanser: if you use it on your faceYou need a gentle, foaming cleanser; micellar water isn't enough here. Start without makeup, on completely dry skin. The alcohol is for the stamp's needle head.
Why is it single-use?
- 1This is a manufacturer requirementThe device is registered as single-use (EU-MDR Class I): according to the manufacturer's instructions, one treatment, one person, and after that it can't be cleaned or reused. This is a requirement.
- 2Every session is a clean startThis way, you start every treatment with a new device, factory-treated with an electron beam and then disinfected by you before use.
- 3Less guesswork at homeYou don't have to wonder how many times you've used it, how clean it stayed, or whether the needles have degraded. One treatment equals one stamp: a simpler, more consistent, more hygienic routine.
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.

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.
If the symptoms get stronger or do not go away, or you see signs of infection (increasing pain, pus, fever), stop and see a healthcare professional.
No makeup for 24 hours. From the next morning, SPF 50 every morning.
What's allowed and what isn't after stamping? →Personal experience, 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.
Age, pregnancy: Under 18. During pregnancy or breastfeeding only after talking to your doctor.
Your skin in the treated area: Open wound, abrasion, burn, fresh scar, active inflammation, eczema, psoriasis, fungal or bacterial infection. Severe acne, a tendency to keloids or abnormal scarring.
Illness, medication: Uncontrolled diabetes, a blood clotting disorder, blood thinners. Active cancer, chemotherapy or radiotherapy. HIV/AIDS, hepatitis or another severe infection.
Allergy: A known allergy to the disinfectant or to the cosmetics you use. If you have a metal allergy, especially to nickel, ask a healthcare professional first: the needles are SUS304 steel, gold-plated.
Where not to use it: Eyelids, the very thin skin around the eyes, mucous membranes, mouth, nostrils, genitals.
For hair loss: if the shedding came on suddenly or is patchy, or if scarring hair loss has been diagnosed, see a doctor about it. The stamp isn't the answer for these.
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?
Stamp gently and perpendicularly: you press down, lift, and don't drag. Divide the area into smaller sections and go over each one 4–6 times, each time a little further along. It's enough when you see mild redness and a few tiny pinpoint spots of blood here and there. The needle is a fixed 1.0 mm and can't be adjusted, so you can't accidentally go deeper.
The goal is even coverage.
Why 1 mm, and why isn't it adjustable?
I didn't want a deeper device for home use. On most of the facial skin, the 1 mm needle reaches at most the upper-middle band of the dermis, the layer where the collagen-producing cells (fibroblasts) are. A simple design: a needle stamp with no moving parts. Press down gently, the depth comes from the length of the needle. Fixed 1.0 mm, it can't be adjusted, so you can't accidentally go deeper. I didn't choose an adjustable one because I don't consider the moving parts of an adjustable head properly disinfectable at home.
When will I get it, and how do I pay?
Cash on delivery for one-time purchases: you pay when the parcel is in your hands. A subscription starts with card payment; card payment is also available for one-time purchases. Foxpost parcel locker 990 Ft, free from 21,000 Ft and with a subscription.
When can I see a change?
The studies on wrinkles and acne scars measured results months after the start, typically between 3 and 8 months. For hair loss, microneedling was added alongside minoxidil, for 3–6 months with regular sessions. These studies used other devices, and I cannot tell you your result in advance.
How does the subscription work?
With the scalp subscription a 4-pack arrives on its own every 4 weeks, with free parcel-locker delivery. In your account, under My subscription, you can skip a pack, pause or cancel. There is no minimum term, and a pack you have already paid for still arrives after you cancel. Payment is handled by the Shopify checkout; I never see your full card number.
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 dozens of models 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 microchannels.

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.
E-BEAM hygiene step
This is what gives the clear protective cap its amber colour
Electron beam treatment during manufacturing
Important: not a sterile device. The effect applies while still sealed.

Electron beam treatment during manufacturing
Important: not a sterile device. The effect applies while still sealed.
- The E-BEAM (electron beam) treatment is a quality-assurance/hygiene boost during manufacturing: the packaged product is briefly exposed to an electron beam.
- Before use, you disinfect the needle head for 60–120 seconds with 70% or stronger alcohol.
- 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.
