The ultimate guide to microneedling.

Microneedling is the practice of creating thousands of microscopic, controlled punctures in the skin with fine, sterile needles, usually delivered by a motorised pen gliding across the surface. Each micro-channel is invisible to the eye and heals within hours. But collectively, they send the skin a powerful message: rebuild.

The proper name, collagen induction therapy (CIT), describes exactly what happens next. The skin’s wound-healing cascade switches on, growth factors flood the area, and over the following weeks fibroblasts lay down fresh collagen and elastin, the scaffolding proteins that keep skin firm, smooth and bouncy. You are not adding anything to the skin. You are persuading the skin to renew itself, using machinery it has owned all along.

That elegance is why microneedling has gone from niche to near-universal on UK treatment menus, and why it pairs so naturally with the rest of the professional toolkit, from chemical peels to dermaplaning.

Microneedling is young by skincare standards, and its origin story runs through three names worth knowing. In 1995, the New York dermatologists Orentreich and Orentreich described subcision: using needles beneath scars to free and rebuild them, proof that needles alone could remodel skin. In the mid-1990s the Cape Town plastic surgeon Des Fernandes took the leap that created the field, designing needle devices to trigger what he named percutaneous collagen induction, publishing the landmark paper in 2002 and establishing needling as a genuine alternative to laser resurfacing.

The German inventor Horst Liebl put the idea into a rolling drum in 2000 (the original Dermaroller), the motorised pen era arrived around 2010, and the watershed for standards came in 2018, when SkinPen became the first microneedling device cleared by the US FDA, dragging a previously unregulated category up to medical-device evidence levels. Thirty years from clinical curiosity to one of the world’s most performed aesthetic treatments: not bad for a technique whose entire premise is a very small hole.

Skin responds to injury in three overlapping phases, and microneedling choreographs all three deliberately:

• Inflammation (day 0 to 3). Platelets and immune cells arrive at each micro-channel, releasing the growth factors that act as the body’s “rebuild here” signal. This is the short window of redness clients notice.
• Proliferation (day 3 to 14). Fibroblasts multiply and begin producing new collagen, elastin and the skin’s own hyaluronic acid. New micro-circulation forms.
• Remodelling (weeks to months). The fast, temporary collagen is steadily replaced with strong, organised type I collagen. This is where texture, scars and lines genuinely change, and why results keep improving for months after a course.

Two practical truths follow. First, patience is part of the protocol: the best results of a session arrive weeks later, which is why honest practitioners photograph, plan and review rather than promise overnight miracles. Second, control is everything: depth, speed, pass count and technique decide whether you trigger productive renewal or pointless trauma. That control is precisely what separates a professional device, and professional training, from a cheap pen bought online.

• Acne scarring. The flagship indication, and the one with the strongest evidence base. Remodelling gradually softens rolling and boxcar scars that creams cannot reach.
• Texture and pores. Fresh collagen plumps and refines the skin’s surface, making enlarged pores appear smaller and rough texture smoother.
• Fine lines and early laxity. Rebuilt scaffolding firms the skin and softens fine lines, particularly around the cheeks, forehead and neck.
• Pigmentation and tone. Renewal helps disperse uneven pigment and brighten overall tone, and microneedling is often favoured for deeper skin tones because it does not target melanin with light or heat.
• Stretch marks and body concerns. The same remodelling logic applies off the face, an established and growing area of practice.

One treatment, mechanical and drug-free, covering scarring, texture, ageing and tone. Like peels, microneedling rewards the practitioner who masters it properly rather than learns it shallowly.

Needle depth is microneedling’s equivalent of peel depth: the single variable that defines result, risk and, in UK practice, who should be holding the pen. As with peels, there is no single statute drawing the lines; industry training frameworks, insurers and device companies draw them instead, and they converge on a familiar pattern:

• Shallower work (around 0.5mm) sits comfortably with qualified beauty therapists with accredited microneedling training, and is widely used for glow, product absorption and early texture work.
• Mid depths (around 1.0mm) are generally treated as advanced practice, with insurers expecting higher-level qualifications (the voluntary UK frameworks map this to Level 5 and above).
• Deeper protocols (1.5mm and beyond), which reliably draw pinpoint blood, are widely treated as medical-adjacent: many insurers restrict them to advanced practitioners or require medical oversight.

The pattern to internalise: your scope is built from your qualifications and your insurance, and it grows as you train. Our pathways are designed around exactly that ladder, from foundation skills in Aesthetic Skincare For Beginners to advanced practice in The Ultimate Skincare Professional.

Demystifying the appointment itself, because informed clients are calmer clients, and trainees should know the choreography before they ever hold a pen:

• Consultation and consent. Skin and medical history, scar and concern mapping, photographs for honest before-and-after tracking, contraindication checks, and a clear conversation about realistic outcomes and session counts.
• Numbing. A topical anaesthetic cream sits for 20–30 minutes for most protocols beyond the shallowest depths, then is fully removed.
• Prep. Skin is cleansed and disinfected; a sterile cartridge is fitted in front of the client (with SkinPen, the single-use lockout makes reuse physically impossible, which is worth watching for as a client).
• The passes. A hydrating glide medium goes on, then the pen travels in controlled, overlapping passes, with depth adjusted zone by zone: deeper where scarring lives, shallower over delicate areas. Uniform pinpoint redness, not bleeding, is the professional endpoint for standard protocols.
• Finish. Soothing, microneedling-appropriate serums (this matters: only properly formulated products belong on open micro-channels), barrier protection, SPF and written aftercare.

Start to finish, expect roughly an hour, of which the needling itself is perhaps twenty minutes.

Microneedling’s recovery is short, but it rewards being taken seriously, and clients appreciate knowing the script in advance.

The rules of the first 48 hours: no makeup until at least the next day, no actives (retinoids, exfoliating acids, vitamin C unless specifically prescribed), no gyms, saunas, pools or deliberate sun, and only the gentle products you’ve been given, because the micro-channels turn everything up. From day three life is normal, with one permanent addition: daily SPF, the bodyguard of every collagen investment.

And how often should the whole cycle repeat? Less often than the internet thinks. Here’s how our founder answered exactly that question at a recent student Q&A, including for clients in their fifties and beyond:

The gym analogy is worth keeping: the session is the stimulus, but the muscle, or in this case the collagen, is built in the rest. Booking more frequently doesn’t buy faster results; it interrupts them.

Microneedling has a dirty secret: the treatment is only as good, and as safe, as the device and the hands holding it. The market is flooded with cheap pens of unknown sterility, inconsistent needle depth and zero clinical evidence. Professional devices exist precisely to remove those unknowns: engineered cartridges that cannot leak fluids back into the device, verified depth accuracy, sterile single-use needle heads and published clinical data.

At MSTA we train on, and recommend, two devices, and they happen to share a parent company (both now sit within the Crown Aesthetics family): SkinPen Precision and MicroPen EVO. Between them they cover the whole professional market, from medical clinics to ambitious solo aestheticians.

SkinPen Precision holds a unique place in microneedling history: in 2018 it became the first microneedling device ever cleared by the US FDA, initially for improving facial acne scars in adults, with a further clearance for neck wrinkles added in 2021. That clearance matters because it forced a standard onto a previously unregulated category: validated engineering, documented sterility and real clinical evidence, with a dossier now spanning more than ninety validation studies.

The engineering is the quiet star. Every treatment uses a sterile, single-use needle cartridge with a patented sleeve that acts as a barrier against cross-contamination, and a lockout system that physically prevents a used cartridge from being fitted again. As a client, that means the hygiene argument is settled by design, not by trust. As a practitioner, it means you are holding the device the medical aesthetics world treats as the reference point.

SkinPen is unapologetically premium. The device and its consumables cost more than the market average, and we won’t pretend otherwise. What you are buying is the deepest evidence base in the category, engineering that protects you and your client, and a consumer brand so strong that, for many clients, SkinPen simply means professional microneedling. Clients search for it by name and will choose a clinic because it offers it. Few devices in aesthetics carry that kind of pull, and it is why SkinPen is our core recommendation, and why MSTA is proud to be the UK’s exclusive SkinPen training partner.

MicroPen EVO is the answer to a fair question: what if you want professional-grade microneedling with a gentler startup cost? Launched by Eclipse in 2021 and brought into the Crown family in 2022, EVO is also FDA-cleared, for facial acne scars and neck wrinkles, and built like it means it: a cordless, aerospace-grade magnesium body, depth adjustment in fine 0.25mm increments, and a safety cartridge designed with active needle retraction.

In our hands-on experience at the academy, EVO simply delivers: consistent, science-backed outcomes that stand confidently beside far pricier setups. Its positioning is deliberately more accessible: a lower entry cost for the device and consumables, which changes the early economics meaningfully for a solo practitioner or new clinic, and UK supply that welcomes Level 3 and Level 4 professionals as well as medics.

You will sometimes hear the split described as “SkinPen for medical professionals, EVO for aestheticians”, and as a picture of typical usage that’s broadly true. But to be clear: it is not a rule. Both devices can be used by qualified skincare professionals and medics alike. The difference is positioning and price, not permission.

Our straightforward guidance, the same we give students:

• Choose SkinPen if you want the category benchmark: the deepest clinical dossier, the strongest consumer brand, and a device clients actively search for. The premium price is the cost of owning the reference standard, and for many clinics it pays for itself in marketing pull alone.
• Choose MicroPen EVO if you want outcomes you can fully stand behind with a more accessible entry point: equally FDA-cleared for its indications, genuinely excellent in practice, and kinder to a young business’s cash flow.

There is no wrong answer between the two, which is exactly why we train on both. What we’d steer you away from, always, is the unverified bargain pen: in a treatment built on controlled injury, “probably fine” engineering is a risk neither you nor your clients should carry.

For completeness, names you’ll meet across the UK industry: Dermapen (the Australian-founded pioneer of the pen format), Dermaroller (the German heritage brand behind the original roller-based collagen induction), SQT bio-microneedling (a needle-free approach using natural sponge spicules, growing fast in UK clinics), and the ubiquitous low-cost online pens, which we’ve already given our honest view on. Knowing the landscape makes you a better adviser to your clients, whatever you practise with.

Three spin-offs come up in every modern microneedling conversation, and a well-trained professional can place each one precisely:

• RF microneedling (devices like Morpheus8 and Potenza) delivers radiofrequency heat through the needles into the dermis, adding heat-driven tightening to mechanical collagen induction. More powerful for laxity and deeper remodelling; also pricier, warmer and firmly in advanced or medical-adjacent territory.
• Nano-needling uses ultra-fine tips that touch only the outermost epidermis: no dermal injury, no true collagen induction, but excellent for product infusion and gentle glow. Honest positioning: a lovely facial-adjacent treatment, not CIT.
• Microneedling with PRP (the famous “vampire facial”) applies the client’s own platelet-rich plasma during treatment to amplify the healing cascade. Because it involves drawing and processing blood, it lives with medical practitioners.

The pattern across all three: the core mechanism is the one this guide has already taught you. Master standard collagen induction properly and every variant becomes a footnote you can evaluate, rather than a mystery you can be sold.

Microneedling is unusually well-evidenced for an aesthetic treatment, and the honest summary goes like this. For atrophic acne scarring, the flagship indication, a 2020 meta-analysis in the Journal of the American Academy of Dermatology and a 2022 systematic review of randomised trials both support microneedling as an effective monotherapy, with visible improvement across studies, while noting that the degree of improvement varies and that combination approaches (including with chemical peels) often perform best of all.

At the device level, SkinPen’s FDA clearances rest on controlled trials for facial acne scars and neck wrinkles, inside a validation dossier its maker counts in the dozens of studies. And mechanistically, percutaneous collagen induction has been documented in the surgical literature since Fernandes’s 2002 paper. Where evidence is thinner, say so: very shallow cosmetic rolling, dramatic pore-size claims and most stacked-treatment marketing rest more on experience than trials. That balance, strong core, honest edges, is exactly how we teach it, and every key source is linked in the references below.

Microneedling’s safety record in trained hands is genuinely good, and it stays that way because professionals respect the no-list. A treatment is postponed or declined for: active acne, cold sores or any skin infection in the area; keloid-prone skin (a hard stop for many practitioners); recent isotretinoin; pregnancy, as a precaution; uncontrolled diabetes or impaired healing; blood-thinning medication, depending on depth; and freshly compromised skin of any kind.

The complications that do occur trace back to predictable causes: infection from poor hygiene or unsuitable aftercare products, pigmentation or track marks from excessive depth and aggression, and granulomas from applying products never designed for open micro-channels. Notice that every one of those is a choice the practitioner controls. The needle is rarely the problem; the system around it is everything, which is the entire argument for training with people who hold clinical standards.

• With chemical peels. Surface renewal plus deep stimulation, sequenced across a plan, is one of the most complete approaches to scarring, texture and pigmentation. (BioRePeel alongside microneedling is a particularly popular modern pairing.)
• With dermaplaning. A cleared, even surface makes needling smoother and serums more effective.
• With targeted serums and home care. The micro-channels dramatically increase absorption, which is an opportunity and a responsibility: only properly formulated products belong on freshly needled skin, a judgement call good training drills deeply.

For clients: professional microneedling in the UK typically runs £100–£300 per session, with London at the top of that range, regional clinics sometimes below it, and RF microneedling starting meaningfully higher. Courses of three to six sessions are usually packaged with a saving. As with peels: a price that undercuts everything around it is usually economising on the things you can’t see, like cartridge quality, training and insurance.

For practitioners, the economics differ from peels in one important way: there’s a device investment and a per- treatment cartridge cost, which is precisely the premium-vs- accessible decision the SkinPen and MicroPen EVO sections above unpack. What the spreadsheet shares with peels is the shape of the revenue: course-based treatment plans, strong session values and natural retail of aftercare, the model our business training is built around.

Microneedling sits at the heart of modern professional skincare, and at the heart of our curriculum. Complete beginners learn it properly, on professional devices, inside Aesthetic Skincare For Beginners. Qualified practitioners deepen and formalise their practice through The Ultimate Skincare Professional and our Executive Courses. And because we are the UK’s exclusive SkinPen training partner, you learn the benchmark device with the people who know it best, taught hands-on in Liverpool by clinicians who use it on real clients every week.
