Opening: Why Choose a “Less Famous” Dermatology Clinic?
In the Korean medical beauty community, greater popularity doesn’t necessarily mean that a clinic is better suited for you.
That’s the conclusion I reached after researching several dermatology clinics in Gangnam. I looked at several frequently mentioned clinics and noticed a common pattern: they emphasized their promotions heavily but provided very little information about actual patient experiences.
DayOne Dermatology Clinic is an exception.
They have two locations right next to each other on Gangnam-daero—one is located at Gangnam Station (4th floor of Hansung Building), and the other is their main branch (5th floor of DaeWon Building), just a few hundred meters apart. When I checked user reviews on BeautsGO, I found that not many people had written about their experiences at DayOne, but those who had were very detailed. It was this sense of authenticity that convinced me.
1. DayOne Dermatology: Brand Background & Two Locations
The name “DayOne Clinic” literally means “Day One”—every day is a new beginning. Their brand philosophy is practical: they focus on delivering real results rather than relying on fancy decorations to impress customers.
DayOne Clinic, Gangnam Station Location (4th Floor of Hansung Building)
- Address: 4th Floor, 423 Gangnam-daero, Seocho-gu, Seoul
- Features: Beige-colored decor, compact waiting area, front desk located near the entrance; the director has three consultation rooms.
- Consultation Area: Separated by transparent glass – you can see the consultations taking place from the outside.
- Independent Treatment Rooms: Multiple treatment rooms, with a large multi-person management room at the back (individual cubicles available).
- Hours: Monday–Friday 10:30–20:30 / Saturday 10:30–16:00 / Closed on Sundays and holidays.
DayOne Main Branch (5th Floor, DaeWon Building)
- Address: 5th Floor, DaeWon Building, 437 Gangnam-daero, Seocho-gu, Seoul.
- Features: Larger in scale than the Gangnam Station location, with more consultation rooms.
- Hours: Monday/Tuesday/Friday 10:30–21:00 / Wednesday/Thursday 10:30–20:00 / Saturday 10:30–16:00 / Closed on Sundays and holidays.
2. Arrival Process: A step-by-step timeline from entry to completion.
11:00 AM: Arrive at Hansung Building.
Exit the Gangnam Station subway and walk for about 5 minutes along Gangnam-daero – the Hansung Building sign is easily recognizable. Take the elevator to the 4th floor, where the DayOne sign will be visible right at the door.
I pushed open the door, and the receptionist immediately greeted me in Chinese, asking if I had a reservation. Since I booked through BeautsGO, she quickly found my reservation and asked me to hand over my passport.
⚠️ Regarding passports: DayOne does not offer any tax-refund process at this time; the passport is simply registered and returned immediately, without being retained. This is different from some other clinics that provide tax refunds, so you can rest assured.
After completing the registration, I waited in the waiting area and was called into the consultant’s office within less than 10 minutes.
11:10 AM – Initial consultation with the consultant (free of charge)
The consultant asked me in Chinese, with the help of an interpreter, about my main concerns: noticeable sagging of the forehead, some drooping of the eyelids, and overall areas that needed lifting.
She then introduced two treatments that I hadn’t anticipated:
① Korean Ultherapy
- The probe can emit three energy beams simultaneously (unlike the single beam used in regular Ultherapy).
- Among Korean Ultherapy devices, this particular model belongs to the higher-energy category.
- The pricing is more affordable than that of US Ultherapy, but the results are more noticeable than those of the basic versions.
- Perfect for those with a limited budget who don’t want weak results.
② Scalp Air Gun
- Primarily used for lifting the forehead and eyebrows.
- The principle involves using air pressure to stimulate the subcutaneous tissue; immediate results can be seen.
- There is very little pain, and the entire procedure takes about 20 minutes.
- Before-and-after comparison photos will be taken.
The consultant explained that while skin lasers and other treatments usually don’t require before-and-after photos, the Scalp Air Gun produces immediate and obvious results, so these photos are necessary.
11:25 AM – Director’s consultation (30,000 KRW)
The director appeared to be in his early 50s and was very professional. He checked the condition of my forehead muscles, pressed them gently, and said, “There is good potential for lifting; the Scalp Air Gun would be suitable for you.”
Then he looked at my side profile:
“If you’re getting Ultherapy, I don’t recommend a full-face treatment – your jawline is in good condition, so focusing on the area from the cheeks to the temples will be enough to achieve the desired lifting effect. This way, the cost is more targeted and the results are more noticeable.”
This recommendation against a full package immediately built my trust in him.
⚠️ Regarding the consultation fee with a director: DayOne charges 30,000 KRW for a consultation with a director; the consultation with a regular consultant is free. If you just want to learn more about the treatments first, you can schedule a consultation with a consultant.
12:00 PM – Price consultation with a consultant
After returning from the director’s office to the consultation area, we finalized the treatment plan and prices. DayOne has very transparent pricing; the consultant printed out the individual prices for each treatment, with no bundled packages offered.
The consultant also mentioned issues related to pigmentation, such as melasma. Multiple sessions would be needed, and the treatments were categorized into Korean local brands and imported products, with significant price differences. The choice of treatment would depend on the severity of the problem and the client’s budget.
12:20 PM – Treatment begins
First, the Scalp Air Gun treatment was performed. It felt like the skin was being gently tapped several times, with almost no pain at all. After the nurse finished, she took some before-and-after photos of my forehead, and indeed, the curve of my eyebrow arch appeared slightly clearer.
Next, Korean Ultherapy was applied to the area from the cheeks to the temples, using a three-line probe. There was a clear “click” sound whenever the energy was delivered, and there was a slight stinging sensation in some areas, especially near the temples. The nurse checked my comfort throughout the treatment, and adjustments could be made at any time. The entire procedure took about 40 minutes.
2:00 PM Completion, Departure
After the treatment, my cheeks were slightly warm, and there was some tightness on my forehead. The nurse applied a soothing mask, and I rested for 20 minutes before leaving.
The clinic provided detailed Chinese instructions for aftercare, listing precautions for that day and the following week—clearly printed, not carelessly photocopied.

6. Real User Reviews
@Xiaohongshu @GangnamBeautyLog: “The s
calp air gun treatment is something I had never heard of in China – but the nurse at DayOne said it’s very common in Korea. After the treatment, my forehead actually seemed to lift a bit. Looking at the before/after pictures, you could clearly see the change in the shape of my eyebrows. The pain was almost non-existent.”
@Weibo @seoulbeauty2026: “The
director at DayOne was very straightforward—they didn’t recommend a full-face Ultherapy treatment but suggested a partial session instead, which saved me a lot of money. This approach of not forcing customers to spend extra really impressed me; I’m glad I tried it.”
@BeautsGO User Review: “Th
e opening of the medication packets was done right in front of me—I could see the batch numbers and the condition of the packaging. This detail is something I really care about, and DayOne met my expectations. After the consultant explained the prices, they provided me with a detailed list without any hidden charges.”
7. FAQ
Q1: What is the difference between DayOne and DayOne Main Branch? A: Both locations use
the same brand standards and pricing system. The main differences are the operating hours (DayOne Main Branch is open until 9 PM on Mondays, Tuesdays, and Fridays, making it more convenient for evening visits) and the size of the premises (DayOne Main Branch is larger than the one near Gangnam Station).
Q2: How does the scalp air gun work, and is it safe? A: It
uses gentle micro-air pressure to stimulate the subcutaneous tissue, promoting blood circulation and enhancing skin elasticity. There are no injections or trauma involved; it’s a safe, non-invasive treatment method.
Q3: Is Korean Ultherapy inferior to American Ultherapy? A: I
t’s not inferior; rather, they serve different purposes. American Ultherapy offers more precise and controllable energy, while Korean Ultherapy delivers stronger results at a better value. DayOne’s three-line probe Korean Ultherapy is considered one of the higher-quality options in Korea, suitable for those who want noticeable lifting effects but don’t have the budget for the American version.
Q4: Is the consultation fee with a director mandat
ory? A: If you require a detailed assessment and treatment plan, a consultation fee of 30,000 KRW applies. If you just want basic information about the treatments, you can schedule a free consultation first.
Q5> Can I choose to have just one treatment? A: Absolut
ely. DayOne doesn’t force customers to opt for multiple treatments. After your consultation, you can decide to have just one or both treatments, or simply have a consultation without any treatment that day.
Q6> Can I fly on the same day after having Ultherapy or the scalp air
gun treatment? A: After Ultherapy, it’s best to avoid strenuous exercise and saunas on the same day, but flying is generally safe. For more invasive treatments, it’s advisable to consult your doctor first.
Q7> Can I view the specific prices of DayOne on BeautsGO?
A: Yes. Search for “DayOne Dermatology” on the BeautsGO app, and you can access the current price list and promotional offers on their clinic page.
8. Who Is DayOne Suitable For?
In DayOne’s waiting area, I observed other customers visiting at the same time:
- A Korean working woman in her 30s, who seemed to be a regular local customer for maintenance treatments
- Two travelers from China who had booked skin boosters and laser treatments through BeautsGO
- A Japanese guest, accompanied by a translator who spoke Japanese throughout the visit
This clinic attracts both local customers and foreign tourists – the high proportion of local clients indicates that its reputation is based on actual results, not just influencer marketing. Customers return because they see tangible benefits.
9. Summary: Who Is DayOne Suitable For?
If you:
- Want to try Korea-specific aesthetic treatments such as scalp air gun or Korean Ultherapy
