What are the indications and contraindications for the Dermapen microneedling device?

The indications for the Dermapen microneedling device include atrophic acne scars, surgical scars, stretch marks, enlarged pores, uneven skin tone, fine lines and wrinkles, as well as scalp care. However, there are certain contraindications for use, including active severe acne, skin conditions such as atopic dermatitis or psoriasis, oral anticoagulants, and pregnancy or breastfeeding. A physician should evaluate the patient before use to ensure their health and safety.

What is the process of Dermapen treatment?

The process of Dermapen treatment typically includes a professional consultation and skin condition assessment, cleansing and makeup removal, and the application of a topical anesthetic to alleviate discomfort. Next, the physician will adjust the needle depth based on the treatment area and use the Dermapen 4™ for microneedling, often simultaneously introducing a high-concentration hyaluronic acid serum to enhance the effect. After the procedure, a cold compress will be applied for soothing, along with the application of calming products. Patients can generally resume normal activities and apply makeup within 24 to 48 hours. The pain experienced during the entire treatment process is usually very mild.

How many Dermapen treatments are needed? Will the effects be visible immediately?

It is generally recommended to undergo 3 to 6 Dermapen treatments as a complete course of therapy, with each session spaced approximately 4 to 6 weeks apart. Some patients may notice a significant improvement in skin glow and plumpness after the first treatment, but collagen remodeling typically takes 4 to 6 weeks to become gradually noticeable. Therefore, patience is key to achieving the best results. Additionally, during each session, the physician may recommend additional treatments based on individual skin conditions to further improve deep scars or other skin issues.

What post-care is needed after Dermapen treatment?

Post-care is crucial for the effectiveness of Dermapen. Patients are advised to avoid intense exercise, sweating, or using alcohol-based skincare products for 48 hours to prevent skin irritation. During this time, focus on enhancing moisture and sun protection by using SPF50+ sunscreen products and opting for physical barriers for additional protection. Additionally, consider combining gentle fruit acids or exosomes to assist in skin repair and enhance the healing effect. If severe peeling or discoloration occurs, patients should return for an examination and treatment by a physician immediately.

Q: What is the Dermapen microneedling pen?

The Dermapen microneedling pen is a fourth-generation medical-grade automated microneedling system, featuring advanced automatic calibration for speed and depth control. It can create up to 1,920 microchannels per second, which is a 104% increase compared to other microneedling technologies. Its needle design uses 33G fine needles, effectively reducing skin pulling and pain, while ensuring comfort and safety during treatment. Dermapen 4™ has received triple medical device certifications from the U.S. FDA, EU CE, and Taiwan TFDA, focusing on improving skin issues such as acne scars, fine lines, and pigmentation.

Q: What is the principle of microneedling therapy?

Microneedling therapy, also known as collagen induction therapy, primarily relies on fine needles to create controlled micro-injuries on the skin, stimulating fibroblasts to produce new collagen and elastin. At the same time, this process opens microchannels in the stratum corneum, enhancing the transdermal absorption rate of active ingredients. This technique effectively targets skin issues such as acne scars, fine lines, and uneven skin tone, achieving repair and improvement. This treatment process is safe and effective, and under the operation of a professional physician, it can better ensure treatment results.

Microneedling principle: collagen induction

Microneedling, also known as collagen induction therapy, creates controlled micro-injuries on the skin with fine needles, activating fibroblasts to produce new collagen and elastin, while also opening the stratum corneum to form micro-channels, significantly enhancing the transdermal absorption rate of active ingredients.
