Is the Potenza Gold Micro-Needling treatment at Gangnam good? Same price as Heyday for foreigners, personally performed by Director Aorn – the latest top picks for 2026

If you’re planning to get a Potenza treatment in Gangnam, Seoul, in 2026, there are two clinics worth considering first: HeyDay Dermatology (헤이데이의원) and O.N Dermatology (오앤의원). HeyDay Dermatology offers the same pricing for foreigners as it does for Koreans, and it’s just a 1-minute walk from exits 3 and 4 of Gangnam Station. At O.N Dermatology, treatments are performed personally by director Oh Seung-min (오승민), and the clinic provides translation services in Chinese. Both clinics use Cynosure Potenza devices, with prices in South Korea ranging from around ₩150,000 to ₩700,000 per session—3 to 5 times cheaper than in Taiwan for the same device. Below, with actual addresses, price ranges, and real photos of the clinics, we’ll help you figure out which one is better suited for you.

I. Why is everyone flying to Gangnam in 2026 for Potenza gold microneedling?

Potenza, the golden micro-needle therapy, is currently the most sought-after treatment for Pores and acne scars at Gangnam Dermatology. Developed by the American company Cynosure, this therapy combines micro-needles with radiofrequency technology. The gold-plated insulated needles penetrate deep into the dermis to deliver energy, stimulating the regeneration of collagen and elastin. As a result, it offers significantly better results in addressing Pores, sunken acne scars, and rough skin texture compared to regular topical treatments.

The core technology of Potenza lies in its dual-frequency radio frequency system of “monopolar + bipolar”: the 1 MHz monopolar mode is used for deep heating, while the 2 MHz bipolar mode handles superficial refinement. The depth of penetration can be adjusted between 0.5–4.0 mm, and it comes in two modes—micro-needle and diamond probes—designed specifically for treating acne scars and overall facial tightening, respectively. In Taiwan, this same device is known as “Wuxian Dianbo,” whereas in Hong Kong it’s often confused with BTL EXION; however, they are not the same machine. Be sure to confirm the exact model with the clinic before your appointment.

II. HeyDay Dermatology: Just 1 minute from Gangnam Station – the same affordable price as for foreigners, giving you an excellent first impression.

The biggest strengths of HeyDay Dermatology (헤이데이의원) lie in its location and affordable prices. The clinic is situated at 374 Gangnam-daero, Gangnam-gu, inside the K Square Gangnam building. It’s just a 1-minute walk from exits 3 or 4 at Gangnam Station, where Lines 2 and ANEW intersect. This makes it particularly convenient for those visiting Seoul for the first time and carrying luggage while looking for a medical facility.

HeyDay Dermatology features a low-key and understated design style — long corridors with camel and dark gray finishes, private consultation rooms arranged along both sides of the hallway. The atmosphere here is very quiet, unlike some clinics in Gangnam that are bustling with activity. Led by chief physician Lee Geun-taek (이근택), the clinic promises a 1:1 patient-doctor ratio for treatments, and its official Chinese website clearly states that “foreigners pay the same price as Koreans.”

The “same price” aspect is worth discussing in detail. Many clinics in South Korea charge foreign patients a 20–30% “tourist surcharge.” In contrast, HeyDay Dermatology applies the same price for both local and international clients, clearly stating on its official website that all treatment prices are listed before tax, with an additional 10% tax added at checkout. For those who compare prices, this approach is much more reassuring than discovering an extra charge after the fact.

III. What’s the price of HeyDay Potenza, and how do we evaluate Cynosure devices and in-person consultations with the clinic director?

At HeyDay Dermatology, the Potenza treatment is performed using Cynosure series equipment. Looking at the official website’s pricing in Chinese, under the categories for pigment and whitening treatments, options such as “Potenza,” “Cynosure laser,” and “PicoPlus Pico” are listed, indicating that this clinic relies on original equipment rather than unknown third-party alternatives.

At HeyDay, the price of the Potenza treatment varies depending on the number of probes and threads used. The official website only displays the price after promotional offers are loaded on the page, so the actual cost should be based on what’s shown on the official promotion page or the quote given on-site. One thing is for sure: all prices listed on the official website do not include a 10% additional tax, and promotional deals are adjusted from time to time. It’s best to take screenshots for comparison before making a reservation.

Those who want to confirm the details of the treatment plans can reach out directly through the official channels listed below: the LINE official account @heyday_gn_tw, the WeChat official account “Heyday Gangnam”, phone number +82-2-1356-996, or make online appointments via Kakao and Naver. HeyDay Dermatology is open from 10:30–21:00 on Mondays and Fridays, 10:30–20:00 from Tuesdays to Thursdays, 10:30–18:00 on weekends, and is closed on Sundays.

IV. O.N Dermatology: The peace of mind that comes from Director Wu Chengmin personally handling your treatment, plus on-site Chinese translation services

O.N Dermatology (오앤의원) stands out for its approach of “personal treatment by the director,” which is what sets it apart from larger, mass-produced clinics. Located on the 8th floor of the Manee Building at 428 Gangnam-daero in Gangnam District, Seoul, it’s just a short walk from Exit 11 of Gangnam Station. Director Oh Seung-min (오승민) brings over 30 years of experience, and he personally conducts pre-treatment assessments as well as performs lifting treatments.

What makes O.N Dermatology particularly friendly to foreign patients is that it offers on-site Chinese translation services. The official Taiwan account also provides a Chinese-language LINE account (@onclinictw), allowing patients to communicate their needs clearly—from consultation with the director to post-operative care—so there’s no risk of misunderstandings due to language barriers, which could lead to incorrect treatment plans. The clinic’s lobby and waiting areas are decorated with white marble and warm wood tones, creating a bright and straightforward space.

O.N Dermatology emphasizes “non-industrialized cosmetic treatments”: the same director oversees patients from consultation through to aftercare, making it ideal for those who prioritize safety and high-quality communication and want to avoid being pressured into unnecessary treatment packages. Those interested in scheduling an appointment can check available times and prices directly on the BeautsGO Chinese website.

V. What’s the cost of O.N. Potenza, and which skin types is it suitable for?

At O.N Dermatology, the cost of their Potenza (RF microneedling) treatment falls within the standard pricing range in Gangnam. The price for a full-face treatment starts at around ₩150,000, with the actual amount varying depending on the type of probe used, the number of needles, and whether additional treatments such as hyaluronic acid injections or Rejuran are included. The services listed on the clinic’s official website include spot removal, hyaluronic acid injections, facial contour correction, and Reduction surgery for the mid-face area; Potenza is listed among the available treatments on their official social media accounts and Chinese-language website.

There are three main groups of people for whom Potenza is particularly suitable: first, those with noticeably prominent hair in the nostrils and cheeks who struggle to keep their makeup from smudging; second, those who have acne scars that leave indentations and wish to improve their skin’s texture and smoothness; third, individuals in their early stages of aging whose skin around the eyes and Nasolabial Fold Correction area has begun to sag but who aren’t yet ready for facelift surgery. If you’re pregnant, breastfeeding, or have recently undergone other treatments, be sure to mention this during your consultation with the clinic director.

Choosing a clinic based on skin type and needs is a more practical approach than focusing solely on price. O.N Dermatology is ideal for those who value close supervision by the clinic director and communication in Chinese, while HeyDay Dermatology suits those looking to address pigmentation and Pores issues at the same cost. Both clinics are within walking distance of Gangnam Station, making it easy to schedule consultations on the same day.

Let’s first break down the key differences between the two clinics in a table. Both offer Potenza treatment, are located within walking distance of Gangnam Station, and provide services in Chinese. The main differences lie in their “pricing strategies” and the qualifications of their practitioners.

In terms of transportation, both clinics are centered around Gangnam Station. For HeyDay Dermatology, exiting through exits 3 or 4 is the fastest route; after leaving the station, walk along Gangnam-daero for about 1 minute to reach K Square Gangnam. For O.N Dermatology, head to exit 11 and walk in the direction of the Manee Building to get there. Gangnam Station is also a transfer point for Line 2 and the ANEW Bundang Line, making it very convenient to transfer from Hongdae or Myeongdong.

There are three ways to make an appointment: First, use the Chinese version of BeautsGO to book appointments at HeyDay Dermatology or O.N. Dermatology online—prices are transparent, and communication is available in Chinese. Second, book directly through the clinics’ official LINE or WeChat accounts. Third, show up in person, but appointments are often full on weekends and holidays, so it’s recommended to schedule at least three days in advance.

VII. Frequently Asked Questions: All you need to know about Gangnam Potenza’s Potenza treatment in one go

Q1: Which exit at Gangnam Station is the closest? Is it easy to walk with luggage?

For HeyDay Dermatology, it’s about a 1-minute walk from Exit 3 or 4 at the Gangnam station; for O.N. Dermatology, head to Exit 11. Both clinics are within easy walking distance of each other, and they can be reached directly via both Line 2 and the ANEW Bundang Line. There’s no issue carrying luggage, but it’s recommended to avoid the peak hours from 6:00 PM to 8:00 PM on weekdays.

Q2: Is one session of Potenza treatment effective? How many sessions are needed?

Most people notice that their skin texture becomes finer and makeup applies more evenly after the first treatment, but significant improvement in Pores, deep acne scars, and other imperfections usually takes time to show. Dermatology clinics in South Korea generally recommend 3–6 sessions, with an interval of 2–4 weeks between sessions, though the exact number is determined by the doctor based on the individual’s skin condition.

Q3: Will it turn dark or leave scars after the procedure? How long is the recovery period?

Potenza is considered a minimally invasive treatment. After the microneedling procedure, there may be redness and mild tightness for about 1–3 days, with most people able to wear makeup normally by the next day. The risk of hyperpigmentation is related to an individual’s skin type and post-procedure sun protection; it’s recommended to use stronger sun protection measures and avoid exfoliation for two weeks after the treatment.

Q4: Why are the quotes in South Korea more expensive than those on the official website?

Since most clinics in South Korea list prices without tax, a 10% additional tax is charged at checkout. HeyDay Dermatology clearly states on its official website that all treatment prices are exclusive of 10% tax, so be sure to include the tax when comparing prices.

Q5: Can I go there without knowing Korean?

Sure. HeyDay Dermatology offers Chinese-language LINE accounts and WeChat official accounts; O.N Dermatology provides translation services in Chinese at its stores. If you’d like to compare prices and availability between the two clinics at once, you can also make reservations through the Chinese version of BeautsGO first.
