Opening: Why Choose a “Less Famous” Dermatology Clinic?
In the Korean medical beauty circle, bigger fame doesn’t necessarily mean more suitable for you.
This is the conclusion I reached after researching seven or eight Gangnam dermatology clinics. I ranked several frequently appearing clinics and found their common characteristics: extremely high promotion density, but very few descriptions of real consultation experiences.
DayOne Dermatology Clinic (데이원의원) is the exception.
It has two locations side by side on Gangnam-daero – one is Gangnam Station location (4F Hansung Building), the other is the main branch (5F DaeWon Building), just a few hundred meters apart. When browsing user reviews on BeautsGO, I noticed not many people wrote about DayOne experiences, but those who did were very specific – this “authentic amateur” feeling was what convinced me.
1. DayOne Dermatology: Brand Background & Two Locations
DayOne Clinic (데이원의원)‘s name literally translates to “Day One” – every day is a new beginning. The brand philosophy is pragmatic: not relying on luxurious decoration to impress, but on real results to retain returning customers.
DayOne Gangnam Station Location (4F Hansung Building)
- Address: 4F, 423 Gangnam-daero, Seocho-gu, Seoul
- Features: Beige-toned decoration, compact waiting space, front desk near entrance, director has three consultation rooms
- Consultant Area: Separated by transparent glass – you can see consultations happening inside from outside
- Independent Treatment Rooms: Multiple rooms, with a large multi-person management room at the back (individual cubicles)
- Hours: Mon-Fri 10:30-20:30 / Sat 10:30-16:00 / Closed Sun & Holidays
DayOne Main Branch (5F DaeWon Building)
- Address: 5F DaeWon Building, 437 Gangnam-daero, Seocho-gu, Seoul
- Features: Larger scale than Gangnam Station, more consultation rooms
- Hours: Mon/Tue/Fri 10:30-21:00 / Wed/Thu 10:30-20:00 / Sat 10:30-16:00 / Closed Sun & Holidays
2. Arrival Process: Real Timeline from Entry to Completion
11:00 AM Arrive at Hansung Building
Exit Gangnam Station subway, walk about 5 minutes along Gangnam-daero – the Hansung Building sign is easy to spot. Take the elevator to 4F, where DayOne signage is visible at the door.
Push open the door, the front desk lady immediately greeted me, asking in Chinese if I had a reservation. Since I booked through BeautsGO, she found my reservation directly and had me hand over my passport.
⚠️ About Passport: DayOne currently has no tax refund process – passport is registered and returned immediately, not held. This differs from some clinics offering tax refunds, so you can rest assured.
After registration, I sat in the waiting area and was called into the consultant’s area in under 10 minutes.
11:10 AM Consultant Initial Consultation (Free)
The consultant asked in Chinese (with translator assistance) about my main concerns: obvious forehead sagging, some eye tail drooping, overall contour needing lifting.
She introduced two treatments I hadn’t expected:
① Korean Ultherapy
- Probe can emit three energy lines simultaneously (different from regular Ultherapy’s single line)
- Among Korean Ultherapy devices, belongs to higher energy level
- Pricing more accessible than US Ultherapy, but more noticeable results than basic versions
- Suitable for those with limited budget but don’t want weak effects
② Scalp Air Gun
- Mainly used for forehead and eyebrow lifting
- Principle is air pressure stimulating subcutaneous tissue, immediate results visible
- Very light pain, entire process about 20 minutes
- Before/after comparison photos will be taken
The consultant said: Skin lasers and skin boosters generally don’t take after photos, but scalp air gun shows immediate obvious results, so comparison photos are specifically taken.
11:25 AM Director Consultation (30,000 KRW)
The director appeared to be in his early 50s, very steady. He checked my forehead muscle condition, gently pressed it, and said: “Good lifting potential, air gun is suitable.”
Then he looked at my side profile:
“If doing Ultherapy, I don’t recommend full face – your jawline condition is good, mainly improving the lifting sensation from cheekbones to temples is enough. This concentrates the cost and makes results more targeted.”
This recommendation against a full package immediately built my trust in him.
⚠️ About Director Consultation Fee: DayOne charges 30,000 KRW for director consultation; consultant consultation is free. If you just want to learn about treatments first, you can book consultant consultation.
12:00 PM Price Consultation (Consultant)
Returning from the director’s room to the consultant area to confirm plan and pricing. DayOne has very transparent pricing – the consultant prints out unit prices for each treatment, no bundled package sales.
Pigmentation issues (like melasma) were also mentioned by the consultant: requires multiple sessions, divided into Korean local brands and imported types, with significant price differences – needs to be chosen based on severity and budget.
12:20 PM Treatment Begins
Scalp Air Gun was done first – the sensation was like skin being lightly flicked many times, pain close to zero. After the nurse finished, she took a set of forehead comparison photos – the eyebrow arch curve was indeed slightly clearer.
Korean Ultherapy (cheekbones to temples area) followed, using the three-line probe. There was a clear “click” sensation when energy fired, with slight stinging at some points – most noticeable near the temples. The nurse checked sensations throughout, adjustments possible anytime. The entire area took about 40 minutes.
2:00 PM Complete, Departure
After completion, cheeks were slightly warm with some tightness in the forehead. The nurse applied a soothing mask, rested 20 minutes before leaving.
The clinic provided Chinese aftercare instructions, listing precautions for that day and the following week – clearly printed, not casually photocopied.

6. Real User Testimonials
@Xiaohongshu @GangnamBeautyLog:
“Scalp air gun is a treatment I’d never heard of in China – DayOne’s nurse said it’s very common in Korea. After completion, my forehead really lifted a bit. Looking at the before/after photos, the eyebrow arch change was obvious. Pain was really close to zero.”
@Weibo @seoulbeauty2026:
“DayOne’s director was very direct – didn’t recommend full face Ultherapy, only said to do partial, saving me a lot of money. This attitude of not forcing consumption still feels good looking back after returning home.”
@BeautsGO User Review:
“Medication unsealing was done entirely in front of me – could see batch numbers, complete packaging condition. This detail I particularly care about, DayOne delivered. After consultant discussed pricing, directly gave me an itemized list, no additional charges.”
7. FAQ
Q1: What’s the difference between DayOne and DayOne Main Branch?
A: Both locations use the same brand standards and pricing system. Main differences are operating hours (Main Branch Mon/Tue/Fri until 21:00, better for evening visits) and scale (Main Branch larger than Gangnam Station).
Q2: What is scalp air gun principle, is it safe?
A: Uses micro air pressure to stimulate subcutaneous tissue, promote blood circulation, help skin elasticity improvement – no injection, no trauma, safe non-invasive treatment.
Q3: Is Korean Ultherapy inferior to US Ultherapy?
A: Not inferior, but different positioning. US Ultherapy has more precise and controllable energy; Korean has stronger energy and better value. DayOne’s three-line probe Korean Ultherapy belongs to higher level among Korean devices, suitable for those wanting noticeable lifting effects but budget doesn’t reach US version.
Q4: Is director consultation fee mandatory?
A: If you need director examination and plan formulation, 30,000 KRW consultation fee applies. If you just want basic treatment information, you can book consultant first (free).
Q5: Can I decide to only do one treatment?
A: Absolutely, DayOne doesn’t force packages. After consultation, you can choose to do only one or both treatments, or do nothing that day and just consult.
Q6: Can I fly same day after Ultherapy/scalp air gun?
A: After Ultherapy, avoid strenuous exercise and sauna that day, but flying is generally fine. For surgery or more invasive treatments, confirm with director.
Q7: Can I see DayOne’s specific prices on BeautsGO?
A: Yes, search “DayOne Dermatology” on BeautsGO APP, enter clinic page to view current month price list and promotional activities.
8. Who Goes to DayOne?
In DayOne’s waiting area, I observed other customers visiting at the same time:
- A Korean working woman in her 30s, appearing to be a regular local customer for maintenance
- Two travelers from China, booked skin boosters and laser through BeautsGO
- A Japanese guest, with translator accompanying in Japanese throughout
This is a clinic with both local customers and foreign tourists – the proportion of local guests indicates reputation stability: not traffic supported by influencer effects, but return rates brought by real results.
9. Summary: Who Is DayOne Suitable For?
If you:
- Want to try Korea-specific aesthetic treatments (scalp air gun, Korean Ultherapy)
- Hope for transparent pricing, no forced consumption
- Are in Gangnam area, free after work or evening (Main Branch until 21:00)
- First time doing lifting treatments, want to consult before deciding
– then DayOne is worth including in your itinerary.
Open BeautsGO APP, search “DayOne Dermatology” or “dayone,” find the location suitable for you, and book a truly worthwhile consultation.
