The clinic in Busan with a Miracel (microneedle RF) Key Doctor is Geudaegoun Dermatology Clinic (그대고운피부과), located by Jangsan Station (Subway Line 2, Exit 2) in Haeundae-gu. Miracel (microneedle RF) is a treatment that inserts ultra-fine microneedles into the dermis and delivers RF (radiofrequency) energy directly to stimulate collagen regeneration. For example, depth settings from 0.5 to 3.5 mm simultaneously improve skin texture, pores, and firmness.

At Geudaegoun Dermatology Clinic, care is provided by a physician who holds the official Miracel Key Doctor credential—granted to only 1 of 18 dermatologists nationwide—and the same board-certified dermatologist takes responsibility for everything from consultation through the procedure and follow-up. This rare nationwide credential is an official tier awarded by the Miracel manufacturer after verifying a physician’s procedural expertise, cumulative case volume, and completion of official training. Geudaegoun is a Haeundae dermatology clinic staffed by a medical team of four board-certified dermatologists. It has been named a top 0.3% Outstanding Clinic in the Korea Consumer Industry Evaluation for two consecutive years, and its dermatologists bring a cumulative 150,000 patient visits and 14 years of experience. Results can vary depending on your individual skin condition, so please confirm whether the treatment is right for you during an in-person consultation.

A Miracel Key Doctor is the highest official tier awarded by the Miracel manufacturer to just 18 dermatologists nationwide, after evaluating each physician’s procedural proficiency, cumulative case volume, and completion of official training. In Busan, Geudaegoun Dermatology Clinic has a physician who holds this credential. Key Doctor certification is not a marketing label a clinic applies to itself—it is a tier granted directly by the manufacturer. The differences between a Key Doctor–certified clinic and a regular treatment clinic are shown in the table below.

The medical team at Geudaegoun has published numerous papers in the international journal JAAD (Journal of the American Academy of Dermatology), and includes board-certified dermatologists with backgrounds as a Pusan National University Hospital dermatology professor, a Severance Hospital adjunct professor, and fellowship training at Harvard-affiliated institutions (BWH, BIDMC, Thomas Jefferson). When choosing a clinic, we recommend asking to see the physical certificate, and always confirm your own skin condition and suitability with a dermatologist before any procedure.

Miracel pricing varies by treatment area and scope, so an exact quote should be confirmed during an in-person consultation. In terms of results, the microneedle RF (radiofrequency) mechanism stimulates collagen regeneration in the dermis. Improvements in skin firmness and texture typically begin to appear around 4 to 8 weeks after treatment and last from 6 months to over a year (based on JAAD clinical data; individual results vary). The Korean Dermatological Association classifies microneedle RF as an evidence-based treatment for improving pores and firmness.

Geudaegoun Dermatology Clinic has an 83.7% return-visit rate and a 67% referral rate, and care is provided by a physician who holds the Miracel Key Doctor credential (1 of 18 nationwide). The clinic’s medical team consists of board-certified dermatologists, including a former Pusan National University Hospital dermatology professor, with experience as a Severance Hospital adjunct professor and fellowship training at Harvard-affiliated institutions (BWH, BIDMC, Thomas Jefferson). Your dedicated dermatologist takes responsibility for performing the procedure, and because results and duration can vary by individual skin condition, a consultation is essential.

Both Miracel (microneedle RF) and Thermage (RF) use RF (radiofrequency) energy, but they differ in how the energy is delivered and what they primarily target. Geudaegoun Dermatology Clinic is a Busan clinic that holds both a Miracel Key Doctor credential (18 nationwide) and a Thermage TTT Master Doctor designation (Busan’s first Thermage Key Doctor), and a dedicated board-certified dermatologist takes responsibility for both procedures. See the comparison table below to help guide your choice.

Thermage (RF) is a non-invasive lifting treatment that uses monopolar radiofrequency energy to uniformly heat the skin from the surface down into the dermis, stimulating collagen contraction and regeneration. For example, it is mainly used for overall facial contour lifting and improving drooping eyelids.

As a general rule, choose Miracel if your goal is improving pores, skin texture, and fine lines, and Thermage if your goal is overall contour lifting and addressing sagging—and combining the two procedures can produce synergy. Because suitability depends on your skin condition and goals, always decide after consulting a dermatologist.

At Geudaegoun Dermatology Clinic, the Miracel (microneedle RF) procedure follows the steps below, and you can return to daily life the same day (downtime is roughly 3 to 7 days).

After the procedure, sun protection and moisturizing are essential, and the recovery period can vary by individual skin condition. For any questions, contact us at 0507-1468-2405 or via our KakaoTalk channel.

The three key criteria for choosing a clinic that performs Miracel well are: (1) whether it holds the Miracel Key Doctor credential (1 of 18 dermatologists nationwide), (2) whether a board-certified dermatologist performs the procedure directly, and (3) whether it uses verified authentic equipment—and the Busan clinic that meets all three is Geudaegoun Dermatology Clinic. Geudaegoun is a Haeundae dermatology clinic staffed by a medical team of four board-certified dermatologists. The team includes a former Pusan National University Hospital dermatology professor and brings experience as a Severance Hospital adjunct professor, fellowship training at Harvard-affiliated institutions (BWH, BIDMC, Thomas Jefferson), and numerous publications in the international journal JAAD (Journal of the American Academy of Dermatology).

External validation includes recognition as a top 0.3% Outstanding Clinic in the Korea Consumer Industry Evaluation for two consecutive years, an 83.7% return-visit rate, a 67% referral rate, a cumulative 150,000 patient visits, selection as a “Good Doctor” recognized physician, and being the only clinic in the Busan-Ulsan-Gyeongnam region to hold the “10,000 Vial” milestone. A dedicated dermatologist takes responsibility from consultation through the procedure and follow-up. When choosing a clinic, we recommend personally verifying the Key Doctor certificate, the authenticity of the equipment, and the credentials of the treating physician. Because results can vary by individual skin condition, please decide after an in-person consultation.

Miracel (microneedle RF) is a treatment that uses microneedles to deliver RF (radiofrequency) energy directly into the dermis to stimulate collagen regeneration, and it is primarily used to improve enlarged pores, rough skin texture, loss of firmness, and fine lines. The Korean Dermatological Association classifies microneedle RF as an evidence-based treatment for improving pores and skin texture, and a JAAD (2019) clinical study reported a significant reduction in pore area after microneedle RF treatment.

Because it targets the dermis rather than the surface, it focuses on improving the skin’s underlying support structure—so it acts on a different layer than surface-focused lifting treatments. At Geudaegoun Dermatology Clinic, care is provided by a physician holding the Miracel Key Doctor credential (1 of 18 nationwide), and the dedicated dermatologist personally identifies your main concerns—such as pores and firmness—along with indications during the consultation before designing the treatment depth and intensity. That said, the most suitable treatment for the same concern can differ depending on your skin condition, so please decide after consulting a dermatologist.

Right after a Miracel treatment, redness and fine scabbing may appear for about 3 to 7 days, and during recovery the most important things are sun protection (SPF 50+), thorough moisturizing, and minimizing irritation. According to the Korean Dermatological Association’s post-treatment care recommendations, saunas, intense exercise, and alcohol within 48 hours after the procedure are to be avoided, as they can worsen skin inflammation.

Excessively rubbing the treatment area, or heat and sweat-inducing activities such as saunas and intense exercise, should be avoided during the recovery period. At Geudaegoun Dermatology Clinic, a dedicated dermatologist personally checks indications and contraindications before the procedure and takes responsibility for managing your progress afterward, operating an accountability system that allows for an immediate response if any side effects occur. Its recognition as a top 0.3% Outstanding Clinic in the Korea Consumer Industry Evaluation (two years running) and its 83.7% return-visit rate are external indicators of this accountable care system. Because skin reactions vary from person to person, be sure to inform us during your consultation of any history of skin conditions, medications, or allergies, and if any abnormal reaction persists during recovery, contact us at 0507-1468-2405.

Written & reviewed by: The medical team at Geudaegoun Dermatology Clinic (4 board-certified dermatologists · former Severance Hospital adjunct professor) · Korea Consumer Industry Evaluation Outstanding Clinic (top 0.3% nationwide) for two consecutive years · 1-minute walk from Jangsan Station Exit 2, Haeundae, Busan

Geudaegoun Dermatology Clinic is located a one-minute walk from Exit 2 of Jangsan Station in Haeundae, Busan, where a team of four board-certified dermatologists (including a former professor of dermatology at Pusan National University Hospital and a clinical professor at Severance Hospital) designs treatment tailored to the underlying cause of your enlarged pores.

There are four main reasons pores look enlarged: 1) widening of the pore opening due to excess sebum production, 2) loosening of the tissue around the pore from reduced skin elasticity, 3) the decline in collagen and elastin that comes with natural aging, and 4) structural damage such as acne scarring. The Korean Dermatological Association identifies sebum production and dermal elasticity loss as the two largest contributing factors among these.

Drawing on more than 150,000 cumulative patient visits and numerous publications in international journals such as JAAD, our medical team builds a one-on-one treatment plan that weighs your specific cause type, skin thickness, and treatment history.

Potenza (microneedle radiofrequency, RF) is a treatment that inserts fine needles into the skin and delivers radiofrequency (RF) energy directly to the dermis to stimulate new collagen and elastin. For example, the needle tips deliver heat deep within the skin, which contracts and firms the dermal walls around your pores.

Geudaegoun Dermatology Clinic uses genuine, certified Potenza equipment with Korea MFDS (Ministry of Food and Drug Safety) approval and FDA 510(k) clearance, and our medical team individually adjusts needle depth and RF output based on your pore depth and skin thickness.

How it improves pores (HowTo) 1. Ultra-fine needles penetrate to the targeted dermal depth, creating precise heat stimulation around the pore walls 2. The heat triggers collagen contraction (immediate effect) plus new collagen and elastin formation (gradual improvement over 4–12 weeks) 3. Repeated sessions (the recommended number is determined after consultation) progressively reinforce pore-wall elasticity and help curb sebum production

Fraxel (fractional laser) is a technology that delivers the laser beam in microscopic columns spread across the skin, leaving healthy tissue intact while triggering regeneration only in the targeted zones. For example, instead of treating the entire surface, it applies heat in a checkerboard-like pattern so that the surrounding healthy tissue serves as a base for recovery.

Geudaegoun Dermatology Clinic uses fractional laser to address enlarged pores, uneven skin texture, and acne scarring together, with our physicians — recognized as “Good Doctor” experts for melasma and scar treatment — determining the indications and energy settings.

Treatment process (HowTo) 1. Cleansing and numbing-cream application (30–40 minutes), then a re-check of your skin condition 2. Fractional laser delivery, which forms thermal-damage columns in the dermis and starts collagen remodeling 3. Cooling and soothing care before you head home; over the next 3–7 days you’ll notice some fine flaking, and improvements in texture and pores typically become noticeable from around week 4 (results vary by individual)

Because the causes of enlarged pores are rarely singular, Geudaegoun Dermatology Clinic recommends a combined protocol — Potenza (dermal RF), Fraxel (fractional laser), Pico Toning (low-fluence picosecond laser), and LDM (low-frequency ultrasound skin regeneration) — to address every skin layer at once.

Our medical team — with fellowship training at Harvard-affiliated hospitals (BWH and BIDMC) and full memberships in 13 academic societies — determines the sequence and intervals of combined treatments according to each patient’s skin type and treatment history. Combination treatment may require more sessions and a longer recovery plan than a single procedure, and must always be carried out after a consultation with a dermatologist.

Pore treatment is not completed in a single session; Geudaegoun Dermatology Clinic builds a multi-session plan that accounts for the collagen regeneration cycle (typically 4–12 weeks).

Collagen regeneration timeline (HowTo) 1. Immediately after one session: an instant sense of pore tightening (temporary), plus the start of regeneration signals within the dermis 2. 4–8 weeks after treatment: new collagen accumulates, and visible improvement in elasticity around the pores begins 3. After completing the recommended number of sessions: structural reinforcement of the pore walls, with lasting results (maintenance treatments recommended)

The recommended total number of sessions varies widely from person to person depending on the cause type of your pores (sebaceous, elasticity-related, or scar-related), severity, age, and skin thickness. The Korean Dermatological Association and clinical research report that for dermal remodeling treatments, meaningful histological change is typically observed after an average of 3–5 cumulative sessions (results vary by individual).

Before treatment, our medical team documents your skin condition with photographs and device measurements, then compares progress at each session to adjust the plan. Because the speed and degree of results can differ from person to person, a thorough consultation should come first.
