The Definitive Guide to Microneedling

Microneedling, also called collagen induction therapy, uses fine needles to create tiny controlled injuries in the skin. This prompts the skin to produce new collagen and elastin. The evidence supports gradual improvements in acne scarring, skin texture and fine lines, and it helps treatments absorb more deeply. On its own, the effect is modest. Its real strength is as an adjunct, amplifying the prescription topicals that do the heavy lifting, whether on facial skin, the scalp or the beard.

Please note, we are an entirely online skin and hair clinic, so we do not offer microneedling. We used to provide it at our former physical clinic, but we now exclusively offer topical skincare treatments that microneedling works best alongside.

What is Microneedling?

Microneedling is a minimally invasive procedure. It uses a device fitted with very fine needles to create thousands of tiny, controlled punctures in the skin. These do two jobs. First, they switch on the skin’s wound-healing response, which lays down fresh collagen and elastin. Second, they briefly open the surface, so anything applied afterwards absorbs more readily. The procedure can be done professionally with a powered pen or a medical roller, or at home with a shorter-needled dermaroller. The same principle is now applied to the scalp for hair loss and to the beard for patchy growth.

How Does Microneedling Work?

The needles create micro-injuries that the body treats as small wounds. Healing them . Over a course of sessions, this can thicken the skin and soften scars and lines. The second mechanism matters just as much. Because the channels briefly increase the skin’s permeability, applied around the treatment further than they would through an intact barrier. This is why microneedling is rarely worth doing in isolation. The procedure opens the door. The topical you pair it with is what walks it.

What Does the Evidence Say About Microneedling?

The evidence is strongest for atrophic acne scars and skin texture. A found microneedling effective for acne scars, both on its own and combined with other treatments. For fine lines and early photoageing, the data is more modest but broadly supportive. A showed dermarolling improved the skin, and that pairing it with other treatments alone. The same pattern holds on the scalp. A found that scalp microneedling plus nightly minoxidil produced perceived improvement in ten out of eleven women.

Two honest caveats run through all of it. Most studies are small and short. And microneedling performs better as part of a combination than alone. It is a supportive treatment, not a standalone cure.

What’s the Difference Between At-Home & Professional Microneedling?

The single variable that separates the two is needle depth. Depth determines safety and what the treatment can actually achieve. Below are the main differences between at-home and professional microneedling:

Please beware that longer needles are sold online to the public but these are not a cheap to professional . Going deeper at home raises the risk of infection, scarring and hyperpigmentation, particularly in deeper skin tones. Anything beyond superficial dermarolling is better done professionally. If you do want to dermaroll at home, technique, hygiene and safety really matter. Always follow the manufacturer’s instructions.

What About Radiofrequency Microneedling?

Radiofrequency (RF) microneedling is a professional treatment that adds heat to the equation. The needles deliver radiofrequency energy into the dermis as they penetrate. This combines the collagen-stimulating effect of needling with deeper tightening. As a result, it tends to do more for skin laxity and deeper texture than standard microneedling. However, it is a more involved treatment, with more downtime and a higher cost. We explain how RF microneedling compares with traditional microneedling in our post on .

Can Microneedling Treat Acne Scars & Skin Ageing?

This is where microneedling earns its reputation. For , a course can soften the depressed, textured scars that topicals alone to shift. For , it can improve fine lines, pore appearance and overall firmness.

The bigger gains, though, come from it with the right prescription actives. is a popular partner. It drives collagen production through a separate pathway, so a retinoid running alongside a microneedling course tends to do more than either does alone (our covers this in depth).

Timing matters, though. Do not apply tretinoin, acids or vitamin C immediately after a professional session. The skin is at its most permeable then, and strong actives can cause significant irritation. Stick to bland, barrier-supporting products for the first days, then slowly return to your actives. Your will provide you with on duration for stopping and actives. A word of caution on melasma too. Microneedling can help deliver depigmenting agents, but aggressive can also worsen . As such, it needs a careful hand and is not a choice.

Does Microneedling Work for Hair Loss?

On the scalp, microneedling works through the same two mechanisms. The response the follicles directly. The micro-channels also help topical minoxidil reach them more effectively. Crucially, the is more convincing than microneedling alone. This matters most for the people who respond poorly to on its own. Around half do, often because of low scalp sulfotransferase activity, and better may help them. It is best thought of as an adjunct to topical treatment for and , not a fix. We cover the scalp protocol, the evidence and how to combine it safely in our post on , and the wider approach in our .

Does Microneedling Help Beard Growth?

The beard follows a different hormonal logic to the scalp, which is worth understanding. On the scalp, androgens like DHT drive hair loss, so treatment often works by blocking them. In the beard, the opposite is true. Facial hair growth is androgen-dependent, so the aim is to stimulate the follicles, not suppress hormones. This is why minoxidil is the mainstay for patchy beard growth, as it works through a vascular, non-hormonal route. It is also why DHT blockers have no role in the beard.

Microneedling works on the beard the same way it does on the scalp. Dermarolling the beard before applying a may absorption and add follicular stimulation. That said, the evidence for beards is more limited than for the scalp, and is extrapolated from it. Beard serums pair minoxidil with supporting actives such as and . Our post on explains how to dermaroll the beard safely.

Is Microneedling Safe?

Microneedling is generally well tolerated. However, it breaks the skin, so it carries real risks if done badly or on the wrong skin. Potential risks and things to be aware of include:

How Do You Get the Best Results from Microneedling?

Like most things in dermatology, microneedling rewards patience and consistency. This applies to at home and professional microneedling. The below principles can help improve your outcomes:

Ultimately, microneedling is a genuinely useful treatment, but it is an amplifier rather than a cure. Whether the target is acne scarring, an ageing complexion, a thinning scalp or a patchy beard, the gains come from combining it with the right prescription topical.
