What Is Microneedling with a Derma Pen Using a Combination of Exosomes, Peptides, Polynucleotides vs NCTF Hyaluronic Acid?
Microneedling with a derma pen using exosomes, peptides, polynucleotides, or NCTF hyaluronic acid is increasingly used to support skin quality, collagen production, hydration, and recovery after treatment. It is one of the more versatile approaches in aesthetic medicine because the treatment itself — the microneedling — can be paired with different regenerative ingredients depending on what the individual skin actually needs.
Many patients researching skin rejuvenation treatments come across these terms but are unsure what they actually mean or how they differ. While the treatments are often grouped together, each ingredient works differently within the skin — and understanding those differences is what allows for a more personalised and effective treatment plan.
Understanding how microneedling works — and how exosomes, peptides, polynucleotides, and NCTF hyaluronic acid may support the skin — can help patients make informed decisions based on their skin concerns rather than trends.
What Is Microneedling with a Derma Pen?
Microneedling is a treatment that uses very small sterile needles to create controlled micro-injuries in the skin. A derma pen is a motorised microneedling device that moves the needles vertically across the skin in a controlled and adjustable way. The depth and speed of the needles can be precisely adjusted, which allows the treatment to be tailored to different skin thicknesses, sensitivities, and concerns.
Microneedling is commonly used for fine lines, uneven skin texture, mild acne scarring, enlarged pores, dull skin, and early skin laxity. Because it works by stimulating the skin’s own repair mechanisms rather than introducing a dramatic external change, it tends to produce results that feel gradual and natural — which suits many patients who are looking for improvement without a significant alteration in how they look.
How Does Microneedling Work?
During treatment, the needles create microscopic channels in the skin. These channels trigger a wound-healing response — the skin begins producing growth factors and collagen as part of its natural repair process. This is the same biological mechanism the body uses to heal any injury, but in a very controlled and targeted way that encourages structural skin improvement rather than scarring.
The temporary channels created during microneedling may also improve the absorption of topical products applied during or immediately after treatment. The skin’s barrier is temporarily more permeable, which means that active ingredients applied at this stage can reach deeper layers than they would through routine skincare application. This is why combining microneedling with exosomes, peptides, polynucleotides, or NCTF hyaluronic acid can enhance the overall outcome beyond what microneedling alone would achieve.
Quick Answer
Microneedling with a derma pen can be combined with regenerative ingredients such as exosomes, peptides, polynucleotides, or NCTF hyaluronic acid depending on the skin concern being treated. Exosomes are commonly used to support cellular communication and recovery, peptides focus on collagen support, polynucleotides are often selected for hydration and tissue repair, while NCTF hyaluronic acid is generally used to improve hydration, skin quality, and overall radiance.
What Are Exosomes in Microneedling?
Exosomes are microscopic extracellular vesicles released naturally by cells. In aesthetic medicine, they are used to support skin recovery and regeneration after treatments such as microneedling. Research into exosomes is still developing, and treatment approaches vary between clinics — but the current evidence suggests they may play a meaningful role in supporting cellular repair and reducing the inflammatory response that follows treatment.
Exosomes may contain growth factors, peptides, amino acids, lipids, and cellular signalling molecules. When applied following microneedling, they are thought to support skin recovery, reduce post-treatment redness, improve brightness, and contribute to a smoother skin texture. They are often considered particularly useful for patients whose skin needs support with recovery as much as stimulation.
What Are Peptides in Microneedling?
Peptides are short chains of amino acids that act as signalling molecules within the skin. They are widely used in medical-grade skincare because they may support skin barrier repair, hydration, collagen stimulation, and recovery after inflammation. When combined with microneedling, peptide serums are often selected for patients wanting gradual improvement in fine lines, mild dehydration, uneven texture, and early ageing changes.
Different peptides target different processes within the skin — some signal the skin to produce more collagen, others support barrier repair, and others help to calm post-treatment inflammation. The specific peptide combination used will depend on the patient’s skin concern and their response to previous treatments.
What Are Polynucleotides in Microneedling?
Polynucleotides are purified DNA fragments commonly derived from salmon or trout DNA. They are increasingly used in regenerative aesthetic medicine and are often selected for sensitive, thin, or fragile skin, under-eye rejuvenation, dehydrated skin, and recovery-focused treatments. Some clinics combine polynucleotides with microneedling to support healing while gradually improving skin hydration and elasticity.
Their primary mechanism is tissue repair and deep hydration rather than surface-level brightening. This makes them particularly well suited to patients whose skin quality is the main concern — where the goal is to restore healthy function rather than simply improve appearance.
What Is NCTF Hyaluronic Acid in Microneedling?
NCTF is a skin revitalising solution that combines hyaluronic acid with vitamins, amino acids, antioxidants, and minerals. Hyaluronic acid is a naturally occurring substance that helps the skin retain water, and NCTF formulations build on this by providing a broader nutritional environment for the skin cells to work with. When used alongside microneedling, NCTF hyaluronic acid is often chosen for patients looking to improve overall skin quality and hydration rather than targeting deeper regenerative concerns.
It is commonly considered for dull or tired-looking skin, early signs of ageing, mild dehydration, and patients wanting improved radiance. For those newer to aesthetic treatments, or those looking for a more preventative approach, this combination can be a gentle and effective starting point.
Which Option Is Best for Different Skin Concerns?
The most appropriate ingredient to combine with microneedling depends on the individual’s skin condition, treatment goals, and medical suitability — not on trends or what is most commonly requested. During a consultation, I assess the skin in detail before making any recommendation.
- Exosomes: Best suited to recovery support, reducing post-treatment redness, improving skin brightness, and supporting cellular repair pathways — particularly useful for skin that has been through previous treatments or is slower to recover
- Peptides: Often selected for early anti-ageing support, improved skin texture, barrier repair, and gradual collagen stimulation — a good choice for patients in the earlier stages of visible skin ageing
- Polynucleotides: Commonly considered for mature or fragile skin, dehydration, under-eye concerns, and skin regeneration — particularly where the focus is on restoring skin quality rather than surface brightness
- NCTF Hyaluronic Acid: Well suited to improved hydration, brighter skin appearance, mild textural improvement, and early preventative treatments — often appropriate for patients new to medical-grade skin treatments
What Affects Results?
Several factors can influence the outcome of microneedling treatments. Skin age and condition, treatment depth, number of sessions, sun exposure, smoking, aftercare, hydration, and existing skin conditions all play a role. Results are usually gradual rather than immediate — most patients require a course of treatments spaced several weeks apart, and visible improvements often continue developing in the weeks following each session as collagen production progresses.
Patients who follow aftercare instructions carefully, avoid sun exposure during the recovery period, and maintain a consistent and appropriate skincare routine between sessions tend to achieve better and more sustained outcomes.
What Happens Over Time?
Microneedling stimulates gradual skin remodelling and collagen production over several weeks. After treatment, it is common to experience temporary redness, mild swelling, skin tightness, and some dryness or flaking — all of which are normal signs of the healing process. These effects typically resolve within a few days depending on the treatment depth used.
When exosomes, peptides, polynucleotides, or NCTF hyaluronic acid are used, improvements are still generally subtle, progressive, and focused on skin quality rather than dramatic change. This is not a treatment that produces an immediate visible result — it is one where the benefits build cumulatively over a course of sessions and continue developing in the weeks that follow.
Who Is Microneedling Suitable For?
Microneedling may be suitable for patients wanting gradual improvement in fine lines, mild acne scarring, skin texture, enlarged pores, skin dullness, and early laxity. However, it is not appropriate for everyone. Treatment may need to be avoided or delayed in patients with active acne infections, certain inflammatory skin conditions, poor wound healing, recent sunburn, some autoimmune conditions, or during pregnancy in certain circumstances.
A medical consultation is important before treatment — not only to confirm suitability but to ensure the most appropriate ingredient combination and treatment depth are selected for the individual’s skin.
Risks and Considerations
Although microneedling is generally considered minimally invasive, side effects and risks can still occur. Possible side effects include redness, irritation, swelling, infection, temporary sensitivity, and post-inflammatory pigmentation in some skin types. The risk of pigmentation changes is higher in darker Fitzpatrick skin tones, and this should be discussed and planned for before treatment begins.
The quality of the device, treatment depth, hygiene standards, and practitioner experience all contribute significantly to treatment safety. Microneedling performed with a medical-grade derma pen in a clinical setting by a trained practitioner carries a different risk profile to treatments performed in non-medical environments — this distinction matters and is worth understanding before committing to any clinic.
Closing Thoughts
Microneedling with a derma pen using exosomes, peptides, polynucleotides, or NCTF hyaluronic acid is not a single treatment but a group of approaches designed to support skin repair, hydration, and rejuvenation in different ways. The needle creates the channel — the ingredient determines the direction of healing that follows.
For patients seeking subtle and gradual improvements that feel aligned with natural-looking outcomes, this regenerative approach can be a well-suited and well-evidenced option. The most appropriate combination depends entirely on the individual’s skin condition, concerns, medical history, and treatment goals — and that is always the starting point for any recommendation I make.
