Dermapen microneedling is a clinically validated skin rejuvenation treatment used to address acne scars, fine lines, enlarged pores, and uneven skin texture. By harnessing the skin's own healing cascade, it stimulates collagen and elastin synthesis without the need for ablative procedures. At Virtuana Clinic in Izmit, Kocaeli, all treatments are performed under physician supervision with personalised protocols for each patient.
The Biological Mechanism of Microneedling: Controlled Injury, Maximum Renewal
Dermapen treatment is founded on the principle of controlled tissue injury. When very fine needles (0.1–0.25 mm in diameter) penetrate the dermis, the body perceives this as a genuine wound and initiates the healing cascade. Three key biochemical pathways are activated in this cascade:
- TGF-β (Transforming Growth Factor-beta) release: Triggers fibroblast activation; increases synthesis of Collagen Types I and III.
- EGF (Epidermal Growth Factor) and VEGF (Vascular Endothelial Growth Factor): Support epidermal cell renewal and vascularisation.
- PDGF (Platelet-Derived Growth Factor): Accelerates tissue repair; this effect is amplified when combined with PRP.
Clinical studies demonstrate that Dermapen treatment increases skin collagen content by an average of 206% and reorganises elastin fibres (Aust et al., Journal of Dermatological Science). This biological response continues for 4–8 weeks; maximum collagen accumulation is seen 3–6 months after treatment. For this reason, a minimum of 4 weeks between sessions is clinically mandatory.
Dermapen vs Other Devices: Which System Is Superior?
Various microneedling devices are available on the market. A comparison of professional-grade devices is summarised in the table below:
| Device | Needle Count | Max Speed (oscillations/sec) | Max Depth | Single-Use Cartridge | RF Feature |
|---|---|---|---|---|---|
| Dermapen 4 | 16 | 1,920 | 3.0 mm | Yes | No |
| SkinPen Precision | 14 | 1,500 | 2.5 mm | Yes | No |
| Rejuvapen NXT | 9 | 1,100 | 2.0 mm | Yes | No |
| RF Microneedling (Morpheus8 etc.) | 24–40 | Variable | 4.0–8.0 mm | Yes | Yes |
Dermapen 4, with its high needle count and speed, passes through the epidermis more uniformly — meaning fewer visible entry-channel marks. RF microneedling provides deeper skin tightening thanks to added thermal energy; however, it carries higher cost and longer recovery time.
Needle Depth Guide: The Right Depth for the Right Result
The most critical parameter in Dermapen treatment is needle depth. Incorrect depth selection can lead to both ineffective treatment and complications:
| Depth | Target Layer | Indication | Recovery Time |
|---|---|---|---|
| 0.25 mm | Upper epidermis | Enhanced active ingredient absorption (serum, PRP), skin tone correction | 0–12 hours |
| 0.50 mm | Epidermal–dermal junction | Superficial wrinkles, pore tightening, skin tone improvement | 12–24 hours |
| 1.0 mm | Superficial dermis | Acne scars (mild–moderate), melasma, skin renewal | 24–48 hours |
| 1.5 mm | Mid dermis | Moderate–deep acne scars, hypertrophic scars, stretch marks | 2–4 days |
| 2.0–3.0 mm | Deep dermis | Deep scars, body stretch marks, severe atrophic scarring | 4–7 days |
Important clinical note: A maximum of 0.5–0.75 mm should be used in thin-skinned areas such as the periorbital region; 0.5–1.0 mm is the limit over bony prominences such as the nasal bridge. For the neck and décolletage, 0.5–1.0 mm is recommended; for body stretch marks, 1.5–2.5 mm is the appropriate range.
Home Dermaroller vs Professional Dermapen: Critical Differences
Home dermaroller use, which has become widespread on social media, leads to serious misconceptions. The key differences between the two approaches are as follows:
| Feature | Home Dermaroller | Clinical Dermapen |
|---|---|---|
| Sterilisation | Inadequate (alcohol alone is insufficient) | Single-use sterile cartridge |
| Depth control | Fixed, non-adjustable | Precise digital adjustment |
| Needle entry angle | 45° (high skin trauma risk) | 90° perpendicular entry (uniform) |
| Speed control | None (dependent on hand pressure) | Adjustable motor speed |
| Anaesthesia | No | Topical anaesthetic cream |
| Infection risk | High | Minimal (sterile environment) |
| Risk of scarring and hyperpigmentation | High (especially in darker skin tones) | Low with controlled protocol |
| Efficacy | Low–Moderate | High |
Another serious problem with home dermarollers is the risk of needle breakage and cross-contamination resulting from the rolling motion. Clinical Dermapen eliminates this issue with its vertical oscillating movement.
How Many Sessions Are Needed? Session Plan by Indication
The number of Dermapen sessions varies according to the type and severity of the concern being treated:
| Indication | Recommended Sessions | Session Interval | First Results Visible |
|---|---|---|---|
| General skin renewal / Brightening | 3–4 | 4 weeks | 2–3 weeks |
| Superficial wrinkles | 3–4 | 4 weeks | 4–6 weeks |
| Pore tightening | 3–5 | 3–4 weeks | 2–4 weeks |
| Mild–Moderate acne scars | 4–6 | 4–6 weeks | 6–8 weeks |
| Deep acne and atrophic scars | 6–8+ | 6–8 weeks | 3–6 months |
| Stretch marks (striae) | 6–10 | 4–6 weeks | 2–4 months |
| Melasma (cautious protocol) | 4–6 | 4–6 weeks | 6–10 weeks |
Virtuana Clinic protocol: A review appointment is scheduled at week 4 after the first session to analyse response and individually revise the session plan as needed.
Dermapen Combined with PRP: The Science Behind the "Vampire Facial"
PRP (Platelet-Rich Plasma) applied simultaneously with Dermapen significantly enhances treatment efficacy. The mechanism of this combination works as follows:
- The micro-channels created by Dermapen allow PRP to penetrate into the deeper layers of the dermis.
- Growth factors in PRP (TGF-β, EGF, VEGF, PDGF) potentiate the healing cascade triggered by Dermapen.
- The platelet-derived fibrin network keeps collagen-producing cells (fibroblasts) active for longer.
Clinical studies show that the Dermapen + PRP combination provides 40–60% greater improvement in acne scar treatment compared to Dermapen alone. At Virtuana Clinic, PRP is prepared from the patient's own blood via a sterile centrifuge process and applied topically during the Dermapen session.
Pre-Treatment Preparation: Steps That Determine Success
Certain preparations are required before Dermapen treatment to achieve the best results:
- 7–10 days before treatment: Vitamin A (retinol) and products containing high-concentration acids are discontinued.
- 5–7 days before treatment: Blood-thinning medications (with physician approval) and omega-3 supplements are stopped.
- 2 weeks to 1 month before treatment: Prophylactic antiviral therapy is initiated if there is a history of herpes simplex.
- Day of treatment: No make-up; attend with clean skin. Topical anaesthetic cream is applied 30–45 minutes before the procedure.
- Active acne, sunburn, eczema or rosacea flare-up: These constitute criteria for postponing treatment.
Post-Treatment Care and Recovery Process
Skin care after Dermapen treatment directly affects the quality of results. The recovery process occurs in four phases:
- 0–6 hours: Intense redness and warmth. Serum and moisturiser are applied; face washing is avoided.
- 6–48 hours: Redness subsides; mild flaking may begin. SPF 50+ sunscreen is mandatory.
- 2–5 days: Mild peeling, bronze/pink appearance. Products containing active ingredients should not yet be used.
- 1–4 weeks: Skin normalises; collagen synthesis continues. Routine skincare is gradually reintroduced.
What to avoid: Exercise, sauna, swimming, heating masks, retinol, AHA/BHA acids, and make-up are prohibited within the first 72 hours post-treatment. Sunscreen use must continue uninterrupted for at least 4–6 weeks.
Contraindications for Dermapen Treatment
Dermapen treatment should not be performed in the following situations:
- Active acne (risk of post-session spread)
- Active herpes simplex or other skin infections
- Predisposition to keloid scarring (hypertrophic scarring may develop)
- Isotretinoin (Roaccutane) use — at least 6–12 months must have elapsed since discontinuation
- Pregnancy and breastfeeding
- Active cancer or ongoing chemotherapy
- Anticoagulant (blood-thinning) medication use (relative contraindication)
- Copper or nickel allergy (some cartridges may contain metal components)
Dermapen Treatment Results: Clinical Evidence
An extensive body of scientific literature supports the efficacy of Dermapen and comparable professional microneedling devices:
- 51–75% improvement in atrophic acne scars (DQAS score) has been reported after 4–6 sessions.
- Efficacy in melasma treatment increases with the addition of trichloroacetic acid.
- In hair loss (androgenetic alopecia), the Dermapen + minoxidil combination has been found superior to minoxidil alone.
- For signs of ageing, significant improvement on the Global Aesthetic Improvement Scale (GAIS) is consistently achieved.

Frequently Asked Questions
Is Dermapen treatment painful? Thanks to topical anaesthetic cream, the procedure is comfortable. As needle depth increases, a mild pressure and warmth sensation may occur; however, severe pain is not expected.
Does Dermapen leave permanent marks? When applied at the correct depth, speed, and protocol, it leaves no permanent marks. A risk assessment should be performed in advance for individuals prone to keloid scarring.
Can Dermapen be done during summer? Yes; however, during periods of intense sun exposure, a shallower needle depth and longer interval between sessions is recommended due to the risk of post-inflammatory hyperpigmentation.
How long does a Dermapen session take? Including preparation, one session generally takes 60–90 minutes. The anaesthetic cream is applied 30–45 minutes beforehand, and the procedure itself takes 20–30 minutes.
