Dermapen 4 Derma Micropen

Dermapen 4｜Introduction of minimally invasive rejuvenation therapy

Procedure Overview and Certification Rationale

Based on the core principle of Percutaneous Collagen Induction (PCI), the microneedle treatment creates a large number of micro-channels in the skin through the use of precision electric microneedles, triggering the body's natural cascade of trauma repair, which in turn systematically rebuilds the structure of the dermis.

The Dermapen 4 (approved name: "Ikumi" Dermapen) introduced by Aresin has passed three international certifications: FDA, CE, and TFDA. It is the only microneedle therapy device in Taiwan that has the above certifications at the same time, and has been granted a Class II medical device license, which requires that it be operated by a physician.

Treatment Machines

After microneedle puncture, the skin initiates a wound repair cascade: platelets and growth factors (PDGF, FGF, etc.) are released, fibroblasts are activated, and collagen and elastin fibers are reorganized and proliferated. The proliferation period is about 7 to 14 days, and the complete improvement effect is gradually visible from 4 to 6 weeks after surgery.

At the same time, the micro-channels formed by the microneedles can significantly enhance the efficiency of transdermal penetration of externally applied active ingredients, so that peptides, growth factors, hyaluronic acid and other restorative essence can reach the dermis layer directly to enhance the overall effectiveness of the treatment.

Equipment Core Technology

The Dermapen 4 is equipped with 16 fine needles that can make up to 1,920 vertical punctures per second. The depth of penetration can be precisely adjusted from 0.2mm to 3.0mm to 0.1mm, which can be flexibly set according to the treatment site and the depth of the lesion.

The AOVN (Advanced Oscillating Vertical Needling) technology adopts a vertical puncture design, which is different from the traditional roller-type angled puncture, and effectively reduces pain during the treatment process, as well as postoperative redness and swelling, shortening the recovery period. The device is equipped with RFID chip syringes and disposable needles, eliminating the risk of cross-infection.

Indications

Clinical indications include: acne pits and various types of acne scars, enlarged pores, rough and dull skin, small wrinkles and mild relaxation, post-surgical scars and stretch marks; localized hyperplastic scars can also be treated with medication injections.

It has also been clinically documented as a complementary treatment for problems such as liver spots, rose spots (rosacea) and ingrown hairs, and can be used in conjunction with mainstream treatments such as electrolysis, chemical peels and hydrafacial injections to achieve a more comprehensive and long-lasting improvement.

Matching Therapy

Differences in orientation from other treatments

Microneedle pen vs traditional roller microneedle: Although both are "microneedles", there is a significant difference between the generations. Traditional rollers are manually operated, creating far fewer micro-channels in 5 minutes than the hundreds of thousands created by an electric microneedle pen, and the angled rolling method creates irregular pulling on the skin, resulting in uneven results and a higher pain level.

Treatment Planning Suggestions

The recommended intervals and frequency for each indication are as follows, with actual planning to be evaluated by a physician based on individual skin conditions: acne scars every 6 to 8 weeks, 4 to 6 times recommended; anti-aging and regeneration every 6 to 8 weeks, 4 to 8 times recommended; skin tone brightening and evenness every 2 to 4 weeks, 4 to 6 times recommended; general skin care every 4 to 6 weeks, 3 to 5 times recommended.

Preoperative Preparation and Postoperative Care

Pre-operative: The skin should be kept clean before treatment, and skin care products containing A-acids should be discontinued for at least 3 days. Inform your doctor of your recent history of filler injections (hyaluronic acid, crystalline ceramics, etc.), current medications, and pregnancy or breastfeeding status.

After surgery: After the treatment, the skin is particularly sensitive and should be protected from prolonged sun exposure with a highly effective sunscreen to minimize the risk of hyperpigmentation. At the same time, avoid scrubbing or rubbing the treated area and follow your doctor's instructions for aftercare. Avoid hot springs, steam baths or swimming for 3 days after the procedure. Use mild cleansers and stop using acid, scrubs or alcohol-based skin care products.

contraindication

Active acne or skin infections, crabs, severe eczema or active roseola, herpes outbreaks, and those receiving anticoagulant medication must be carefully evaluated by a physician before scheduling a course of treatment. Persons under 18 years of age must be accompanied by a legal guardian and sign a consent form.
