If you plan to visit Seongsu-dong against the wind and also want to take care of your skin, then this article is for you. For locals, Seongsu-dong is just a place to hang out on weekends – with coffee shops, stylish boutiques, and a long street full of options. When it comes to dermatology clinics in this area, the most frequently mentioned ones are Allup, Sosu, and Bellis. Today, we’ll give you an in-depth look at these three clinics.
Which clinic in Seongsu-dong do you recommend for facial treatments?
Allup Dermatology: Offers a wide range of treatments suitable for those looking to address multiple skin issues at once.
Allup in Seongsu-dong provides a fairly comprehensive range of services. From basic cleansing and pore management to advanced treatments like picosecond lasers, Ulthera, and hyaluronic acid injections, they have almost everything you might need. The consultants here are very professional and take the time to understand your skin type before recommending a treatment plan—they don’t just push the most expensive options on you.
I asked a Korean friend who lives nearby, and she said she often goes to Allup for microneedling and pore treatment, as well as hyaluronic acid injections. She said, “If you want to choose your treatments carefully without going over budget, go to Allup.” In other words, the consultants there are more reasonable and won’t try to sell you unnecessary extra services.
The interior of the clinic is simple, clean, and modern. The waiting area is small but well-organized. If you want to address multiple skin issues in one go, Allup is a great choice.

Sosu Dermatology: For those with sensitive skin, their Hydra Facial treatment is highly recommended.
Sosu is quite popular in Seongsu-dong, and the atmosphere there is very feminine and comfortable. The receptionists speak both Chinese and English, making it easy for international visitors.
The most talked-about treatment at Sosu is their Hydra Facial. It combines deep cleansing, hydration, and other steps to improve skin with large pores or other issues. A friend who tried it said that the blackheads around her nose were removed so thoroughly it was like using a camera to clean them—her skin felt incredibly clean afterward. This real-life review really impressed me.
In terms of prices, a single Hydra Facial treatment at Sosu costs around 200,000 Korean won. If additional treatments like picosecond lasers are added, the total cost may range from 300,000 to 400,000 won. They are especially good at treating skin with large pores.

Bellis Dermatology: Comprehensive facial treatments at affordable prices, suitable for those with moderate budgets.
Bellis was previously featured in a detailed article; here’s a brief overview of its position among the three services. If Allup offers a full range of treatments and Sosu is an advanced option for pore care, then Bellis represents the entry-level comprehensive care solution.
Bellis’ comprehensive facial treatment costs around 280,000 to 350,000 Korean won and includes deep cleansing, hydration, light therapy, and a soothing mask. I asked about it personally, and they said they would recommend the right treatment based on your skin condition without forcing anything on you. It’s ideal for those who want to improve their overall skin health but don’t have a large budget.

Comparison of the three services: Each has its own strengths—choose according to your needs.
| Dimensions | Allup | Sosu | Bellis |
|---|---|---|---|
| Range of treatments | Most comprehensive | Focused on pore management | Comprehensive care as the main focus |
| Price range | 200,000 – 600,000 Korean won | 200,000 – 400,000 Korean won | 280,000 – 350,000 Korean won |
| Consultation-style service | Detailed assessment of skin condition | Relaxed and comfortable experience | Directly corresponds to the prescription. |
| Suitability for foreigners. | Moderate. | Relatively high. | Moderate. |
| Who is it most suitable for? | Those with a generous budget and multiple skin concerns. | Those with large pores who want to reduce the appearance of blemishes. | Those with a moderate budget who seek stable results. |
Actually, none of these three options is absolutely the best; the one that best matches your needs is the best choice. If you just want to use a short vacation to improve your overall skin condition, Bellis offers a better value for money; if you have large pores and many blackheads, Sosu is more targeted; if you have multiple skin issues that you want to address at once, Allup offers the greatest flexibility in its treatment packages.

When going to the spa in Seongsu-dong for dermatology treatments, make sure to use BeautsGO for reservations.
Most dermatology clinics in this area of Seongsu-dong serve local customers primarily, so their reviews are generally good. However, if you don’t speak Korean, it might be a bit difficult to communicate directly. For example, phrases like “count them directly” may not be understood as quickly as you expect when compared to requests like “check my pores” or “get pore treatment.”
The biggest advantage of using the BeautsGO app for reservations is that you can communicate entirely in Chinese. You don’t need to worry about how to describe your skin concerns in Korean—just write down your requirements in Chinese before booking, and the staff will handle the details for you. Once you arrive, everything will go smoothly without the need for further communication.
BeautsGO also displays the total cost in advance, so you can be prepared before going, avoiding unnecessary extra services at the spa.
Practical tips
- Reservations should be made in advance: Weekends and holidays are usually the busiest times, so it’s recommended to book at least 3–5 days in advance using BeautsGO.
- Stop using acidic products for 2–3 days:暂时 avoid using fruit acids, salicylic acid, retinol, and other irritating substances to reduce irritation.
- Come without makeup: The staff will help you remove it before the treatment, saving you time.
- Bring your passport: It’s required for foreign visitors to register.
- Post-treatment sun protection: After light therapy treatments, the skin is more sensitive, so sun protection is essential.
- Do not apply makeup on the same day: Return to the hotel immediately after the treatment to allow your skin to fully absorb the benefits.
