Microneedling — Does It Still Have a Place?

One of the oldest techniques in modern aesthetic medicine is also one of the most misunderstood. Here is an honest clinical account of what actually does, what the science says about penetration, and where the procedure sits in a treatment landscape.

A technique with a longer history than its current marketing suggests

is frequently as though it were a recent innovation; a of the and energy-based era. In fact, the concept of using controlled skin injury to stimulate collagen most of the treatments that now share its clinical space.


The modern dermaroller, the device that brought the technique into widespread aesthetic was in the mid-1990s by Dr. Fernandes, a South African surgeon, who that repeated needling of the skin produced progressive in texture, firmness, and scar architecture. His were clinically astute, and the biological mechanism he was exploiting has since been characterised in scientific detail.

What microneedling actually does

Microneedling, formally termed percutaneous collagen induction therapy, works by creating thousands of micro-injuries in the epidermis and upper dermis using fine needles. These micro-injuries trigger the skin's intrinsic wound healing cascade, a precisely orchestrated sequence that unfolds in three phases: an initial inflammatory response in the first 24 to 72 hours, a proliferative phase lasting days three to fourteen during which new and elastin fibres begin forming, and a remodelling phase that for weeks to months as the new and


The main mechanisms associated with are collagen and elastin production, transient increases in skin permeability, and improved skin barrier post-treatment. As the wound repair is initiated, to the wounded area to collagen and production, contributing to firmness and of the healed epidermis.


vascularity enhances the delivery of and growth to the tissue, to the overall in skin quality that goes beyond what collagen stimulation alone would .

Is Needle depth important and what it determines

The depth to which penetrate determines which tissue layer is targeted and, consequently, what clinical effect is


0.5mm, needles the epidermis and dermis, primarily enhancing topical and improving skin quality.


At 0.5 to 1.5mm, needles reach the dermis and initiate meaningful collagen .


At 1.5 to 2.5mm, the reticular dermis is targeted, producing the most significant collagen stimulation, but with the most significant post-procedure .


This depth-effect relationship has important clinical . A 0.3mm used at home bears little resemblance to a 1.5mm in its effects, however the devices may look.


The marketing that the two or that implies home microneedling the same clinical result as a professional treatment is not patients .

From manual to motorised — and why it matters

The relies on manual pressure and a to drive needles to the depth . The shift to motorised microneedling pens in which needles at high speed and penetrate vertically rather than at an angle represented a genuine clinical advance.


Vertical needle penetration the epidermal tearing that can occur with rolling motion, produces more consistent depth control across areas and skin thicknesses, and allows depth and speed to be within a single treatment session.


The motorised pen is now the standard for good clinical reasons, and Exosomes those reasons go beyond marketing preference. It is for these sound that at the Cosmetic Company in Esher, Surrey we use the

The topical penetration question — and its surprising answer

One of the most clinically discussed of is its capacity to enhance the penetration of .


The logic is intuitive: create microchannels through the stratum corneum, apply beneficial ingredients, and those ingredients will more deeply than they could through intact skin.


This logic is correct in principle. The clinical is more and in one important respect, genuinely surprising.


skin sites recover properties within approximately two hours. Hence the effective penetration window for applied is considerably shorter than most post-procedure protocols


More significantly, topical agent applied immediately before penetrated deeper compared to agent applied afterward at one and three hours, with demonstrating lateral beyond microchannels with increased over time. This finding, that pre-application may deeper penetration than post-application, challenges the clinical that topicals should be applied after and raises important questions about the of topical in a microneedling protocol

What topical serums are worth using and when

Given the penetration described above, the strategy deserves more clinical thought than it typically .


The ingredients with the strongest rationale for are those with a effect on wound and recovery: acid for surface hydration and tissue support, growth factors and PDRN for wound healing acceleration, and ceramide-based formulations to barrier recovery as the microchannels reseal.


The trendy examined in namely exosome complexes, cocktails, and NAD may have a more defensible delivery window via application than via use. The questions about their activity after formulation, and about whether they are optimally sized for microchannel penetration, remain.

The clinical indications where microneedling genuinely excels

The base for microneedling is in several specific indications.


Acne scarring — particularly rolling and boxcar scars has a to sessions, with evidence of genuine dermal remodelling and clinical in scar depth and texture.


Skin quality improvement in texture, tone, pore appearance, and the overall quality of the dermal matrix is consistently demonstrated across a broad range of studies. has been widely in for acne scar treatment, skin rejuvenation, hair loss, melasma, and skin cancer, with the micro-channels formed facilitating delivery of cosmetic agents while stimulating and elastin through the cascade.


The for stretch marks and for certain presentations of is more variable but clinically . The evidence for hair loss, particularly in with topical minoxidil, is growing and genuinely interesting.

Where microneedling sits in a contemporary treatment landscape

Standard microneedling genuine and well-evidenced without the thermal component that energy-based introduce.


For with darker skin types, where the risk of hyperpigmentation with is a meaningful consideration, offers a safer path to collagen stimulation. Its cost profile, both for the clinic and the patient, makes a series of treatments more than alternatives. And its capacity to penetration, understood and properly managed, adds a clinically useful that energy-based cannot replicate in the same way.

Summary

has a well-established, well-evidenced role that has not been by newer . It works through a mechanism that is characterised and consistently .


The results in appropriate indications i.e. acne scarring, skin and stimulation are real, meaningful, and durable when a proper series of is completed.


The dimension is important but more than standard protocols acknowledge. The that Dr. developed in the 1990s remains, in 2025, a useful and scientifically credible tool in the aesthetic medicine repertoire. Not everything that has come since has earned the right to it.


The views expressed in Clinical are the Dr Forrester’s own and his personal and professional in .
