2.1 Clinic environment and service experience
TUP Dermatology Clinic is located in a conveniently accessible area in downtown Seoul. The clinic is designed in a modern, minimalist style, with a white color scheme and streamlined layouts, creating a clean and fresh atmosphere. The waiting area is spacious, so there is no sense of crowding. The staff are generally young and energetic, and their service attitude is friendly.
The reservation process is quite user-friendly for Chinese customers. It is possible to communicate in advance through WeChat or official channels, and the staff have basic Chinese language skills or can assist with translations. During the consultation, there is no excessive pressure to make purchases; doctors provide specific recommendations based on the patient’s skin condition, which gives patients a sense of confidence.

2.2 Main Treatments and Efficacy
TUP’s core strengths lie in skin management and laser treatments:
- Skincare Treatments: These are TUP’s signature services, particularly effective for issues such as pores, uneven skin tone, and acne scars. It is generally recommended to undergo 3-5 treatments, spaced 2-3 weeks apart, for noticeable improvements in skin quality.
- Picosecond Lasers: TUP excels in treating spots and pigmentation issues, thanks to well-maintained equipment and highly skilled physicians.
- Hyaluronic Acid Injections: These provide deep hydration, leaving the skin feeling soft and supple. The effects last for about 2-3 months.
- Pico Laser: Ideal for those looking to improve their overall skin texture, this treatment requires no long recovery time and allows for normal daily activities.
According to customer feedback, TUP’s strength lies in achieving visible results that look natural—without creating an overly artificial “tweaked” appearance. Instead, the skin appears to have been upgraded to a higher quality.

2.3 Cost Information
TUP’s prices are considered mid-to-high among Seoul’s dermatology clinics, but they offer good value for money.
- The cost for a single skin treatment is approximately 150,000 to 250,000 Korean won.
- Picosecond lasers cost around 300,000 to 600,000 Korean won, depending on the area treated.
- Hydrofacial treatments cost approximately 200,000 to 350,000 Korean won.
- Combo packages are usually more cost-effective than individual treatments; you can inquire about them during a consultation.
The total costs are relatively transparent. After a consultation, you will be clearly informed about the fees for each service, with no vague estimates.

III. Detailed review of Gao Yongxu Dermatology
3.1 Location and style of the clinic
Gao Yongxu Dermatology stands out for its “director-brand” reputation—the entire clinic’s credibility and word-of-mouth are largely built on Director Gao Yongxu’s personal expertise. Such clinics are not uncommon in Korea, but Gao Yongxu has managed to establish a solid foothold in the highly competitive Seoul dermatology market, indeed thanks to his proven technical skills and positive reputation.
The clinic’s environment is refined and understated; it does not pursue a “internet-famous” look but instead focuses on creating an atmosphere that conveys “this is a place where medical care is taken seriously.” The waiting areas are well-designed, and privacy is carefully protected, ensuring that each patient receives consultations and treatments in a relatively private setting.

3.2 Core Strengths: Injection Treatments
What Gao Yongxu Dermatology is most renowned for are its injection-based anti-aging treatments. The clinic director has extensive clinical experience in areas such as hyaluronic acid and botulinum toxin injections, and his techniques are precise and deliver natural results.
- Hyaluronic Acid Filling: Fillings in areas such as the nasolabial folds, tear troughs, and apple cheeks provide natural results without excess. The clinic director carefully controls the dosage to prevent the face from looking puffy.
- Botulinum Toxin Injections: These treatments for forehead wrinkles, crow’s feet, and masseter muscle reduction are highly praised. The dosage is precisely controlled, ensuring natural expressions after the procedure.
- PLLA Face Lifts: These collagen-stimulating treatments are suitable for mild signs of aging and help improve overall skin elasticity. Results are gradual but long-lasting.
- Thread Lifts: Ideal for mild to moderate sagging, these procedures work best when combined with injection treatments.

3.3 Fee Information
Gao Yongxu Dermatology offers relatively high-end pricing, which is related to the fact that all consultations are conducted by the clinic director in person:
- Hyaluronic acid (per vial): Approximately 600,000 to 1,000,000 Korean won (varies by brand and area of application)
- Botulinum toxin: Approximately 300,000 to 500,000 Korean won (depends on the injection area)
- Youthful appearance injections: Approximately 600,000 to 800,000 Korean won
- Thread lifting: Prices vary depending on the area and number of threads used, usually starting from over 1,000,000 Korean won
Although the costs are not low, having consultations conducted personally by the director means that it is less likely that an assistant will perform the procedures on your behalf. This is a significant guarantee for customers who need injectable treatments.
