Microneedling has quickly become one of the most popular non-surgical skin treatments in aesthetics — and for good reason. It is highly effective, minimally invasive, suitable for a wide range of skin concerns, and requires very little downtime compared to more aggressive resurfacing procedures.

Using advanced devices such as the Genosys Dermafix Pen, microneedling helps stimulate the skin's natural healing response to improve fine lines, skin texture, acne scarring, pigmentation, enlarged pores, and overall skin quality.

In simple terms: it encourages your skin to repair itself more efficiently. Which, frankly, feels like a useful life skill in general.

What is microneedling?

Microneedling — also known as collagen induction therapy — is a treatment that creates tiny, controlled micro-injuries within the skin using ultra-fine sterile needles. These microscopic channels stimulate the body's natural repair response, encouraging increased production of collagen and elastin — the proteins responsible for keeping skin firm, smooth, elastic, and youthful-looking.

As collagen levels increase over time, the skin gradually becomes smoother, firmer, more refined, and more even in tone and texture.

What is the Genosys Dermafix Pen?

At Radiant, microneedling is performed using the Genosys Dermafix Pen — a professional-grade automated microneedling device designed to deliver precise, controlled treatment with improved comfort and consistency. The device uses ultra-fine needles that move rapidly across the skin to create uniform microchannels at adjustable depths.

Key features include adjustable needle depth, high-speed oscillation, precise treatment delivery, sterile single-use cartridges, and the ability to combine with active serums. This allows treatments to be tailored for different skin concerns and areas — including more delicate regions such as around the eyes. Because not all skin areas appreciate the same level of enthusiastic needling.

What skin concerns can microneedling help with?

One of microneedling's biggest strengths is its versatility. It can improve:

Microneedling can also be used on the scalp to support hair restoration treatments.

How does microneedling actually work?

Microneedling works by triggering the skin's natural wound-healing process, which happens in three stages:

1

Inflammation phase

The controlled micro-injuries stimulate blood flow, immune response, and cellular activity. This initial response signals the skin to begin repairing itself.

2

Proliferation phase

Fibroblast cells become activated and begin producing new collagen and new elastin. This is where improvements in texture, firmness, and skin quality begin developing.

3

Remodelling phase

Over the following weeks and months, the skin continues rebuilding and strengthening itself — resulting in gradually smoother, firmer, healthier-looking skin. Essentially, microneedling tricks the skin into behaving like it is younger and significantly more motivated.

Why combine microneedling with serums?

One major advantage of microneedling is that the temporary microchannels created during treatment allow active ingredients to penetrate more effectively. This means treatments can be combined with serums containing hyaluronic acid, peptides, vitamins, and growth factors to further enhance hydration, healing, and skin rejuvenation. Your skincare products finally get invited beyond the front door instead of sitting on the surface hoping for the best.

What happens during a microneedling treatment?

A typical session usually lasts around 45–60 minutes depending on the treatment area.

Consultation

Your practitioner will assess skin concerns, medical history, treatment suitability, and desired outcomes before proceeding.

Preparation

The skin is thoroughly cleansed and a topical numbing cream is usually applied to improve comfort before treatment begins.

Treatment

The Genosys Dermafix Pen is passed carefully across the skin in a controlled pattern. Most patients describe the sensation as mild buzzing, light scratching, or slight vibration — rather than pain.

Post-treatment care

After treatment, soothing products are applied to calm and hydrate the skin. At Radiant, LED light therapy is often used as an additional post-treatment boost to reduce redness, calm inflammation, and support healing.

What is recovery like?

Downtime is generally minimal. Most patients experience mild redness, slight tightness, and temporary sensitivity — similar to a mild sunburn — for 24–48 hours. Some mild dryness or flaking may occur as the skin heals, but this usually resolves quickly.

Aftercare advice

Proper aftercare helps support healing and optimise results:

Avoid makeup for 24 hours — give the skin barrier time to recover before applying anything to the surface.
Wear SPF daily — treated skin is more sensitive to UV. Daily sunscreen is essential.
Use gentle skincare — stick to mild, hydrating products and avoid anything harsh or heavily active.
Avoid retinoids and exfoliants temporarily — these are too strong for freshly treated skin. Reintroduce gradually once healed.
Avoid saunas, steam rooms, and swimming pools — for several days after treatment to allow proper healing. So perhaps avoid experimenting with seventeen active ingredients immediately afterwards.

How many treatments are needed?

For general skin rejuvenation, typically 3–6 sessions spaced 4–6 weeks apart are recommended. Acne scarring or deeper wrinkles may require additional treatments and longer-term collagen remodelling. Some patients notice improvements after the first session, but collagen production continues developing over several weeks to months — because collagen, annoyingly, does not operate on immediate gratification.

Is microneedling safe?

When performed by trained professionals using medical-grade devices, microneedling is considered very safe. Temporary side effects can include redness, mild swelling, dryness, sensitivity, and light flaking. Serious complications are rare when sterile protocols and appropriate aftercare are followed.

Who should avoid microneedling?

Microneedling may not be suitable for patients who are pregnant or breastfeeding, have active acne infections, have eczema or psoriasis in the treatment area, have certain healing disorders, are prone to keloid scarring, or are taking some blood-thinning medications. A consultation helps determine whether the treatment is appropriate and safe.

Microneedling with the Genosys Dermafix Pen is one of the most effective non-surgical treatments for improving overall skin quality. By stimulating collagen production and encouraging natural skin repair, it can help improve fine lines, acne scarring, pigmentation, texture, firmness, and skin radiance — all with relatively little downtime. At Radiant, treatments are tailored to each individual's skin concerns and goals to create safe, natural-looking results and healthier skin long-term. Because sometimes the most impressive skin rejuvenation comes not from adding something artificial — but from encouraging your own skin to do what it was designed to do all along.
