A Genuine Medical-Grade Device — Not All Microneedling Is the Same

Not every microneedling device on the market is created equal — and the difference genuinely matters for your safety and results. The Original Dermapen 4® is FDA-cleared (Clearance No. K221070) specifically for the treatment of facial acne scars, alongside CE certification, TGA certification, and Taiwan Ministry of Health and Welfare approval. It’s used by over 20,000 professionals across 108 countries, with more than 7 million treatments performed. Many microneedling pens marketed to clinics and consumers carry no such clearance at all — at Eva Clinic, we use the genuine Original Dermapen 4, not an imitation device, precisely because this regulatory clearance reflects real safety and performance standards that lower-grade devices simply haven’t met.

How AOVN™ Technology Works

Dermapen 4 uses patented Advanced Oscillating Vertical Needling™ (AOVN™) technology — a precise, vertical up-and-down needling motion (rather than the dragging or rolling action of older devices) that creates up to 1,920 micro-channels per second through 16 fine needles in a single-use, sterile cartridge. This vertical action minimises trauma to the skin compared with dermal rolling, meaning the skin can focus its energy on genuine healing and regeneration rather than repairing collateral damage caused by the treatment technique itself. Needle depth is digitally controlled from 0.2mm to 3.0mm in precise 0.1mm increments, with an RFID safety chip automatically calibrating each new cartridge — allowing treatment to be precisely tailored to your specific skin concern and the area being treated, from delicate under-eye skin to deeper acne scarring.

Key Benefits

• Collagen & Elastin Stimulation: The controlled micro-channels trigger your body’s natural wound-healing response, releasing growth factors that stimulate genuine new collagen and elastin production — enhancing skin texture and elasticity from within, not just on the surface.
• Scar Reduction: Effectively diminishes the appearance of acne scars, surgical scars, and stretch marks, with Dermapen 4 being the only device on the market with a dedicated Scar Treatment (“ST”) setting specifically calibrated for this purpose.
• Anti-Ageing Effects: Reduces the appearance of fine lines and wrinkles, leading to a smoother, more youthful-looking complexion.
• Improved Skin Tone & Texture: Addresses enlarged pores, uneven pigmentation, and sun damage.
• Enhanced Product Absorption: The micro-channels created allow for significantly deeper penetration of topical treatments applied afterwards, maximising their effectiveness compared with applying the same products to intact skin.
• A Safer Alternative to More Invasive Options: Because treatment depth and speed are precisely, digitally controlled, Dermapen 4 offers many of the collagen-stimulating benefits of laser resurfacing with less downtime and a different risk profile — a genuine option for clients wanting real results without more intensive treatment.

What Dermapen 4 Can Treat

• Acne scars, including atrophic (indented) scarring

Treatment Details

Most treatment plans involve a course of 3–6 sessions, spaced approximately 4 weeks apart, allowing your skin’s natural collagen remodelling process to properly complete between treatments. Where Dermapen 4 is combined with other injectable treatments (such as the collagen-boosting biostimulators covered elsewhere on our site), a spacing interval is maintained between the two to protect skin integrity and results — this will be planned specifically for you as part of a wider treatment plan if relevant.

What to Expect: Preparation, Sessions & Aftercare

Before your session: discontinue retinoids, AHA/BHA exfoliants, or other abrasive skincare for 72 hours prior, and arrive with clean skin free of makeup or heavy moisturiser.

During treatment: a topical numbing cream is typically applied beforehand for comfort. The treatment itself is quick, with the digitally controlled AOVN technology delivering consistent, precise results across the treated area.

After treatment: skin will appear red, similar to mild sunburn, immediately afterwards — this is a normal, expected response. Medical-grade SPF 50+ sunscreen is essential in the days following treatment to protect healing skin and prevent UV-induced pigmentation, and harsh exfoliants or excessive heat exposure should be avoided for 5–7 days.

Results timeline: initial improvement can be visible from around 10 days post-treatment, with most clients seeing meaningful results within 6–8 weeks, and continued improvement for up to a year following your first treatment as collagen remodelling continues.
