Introduction to Sia’s Dermatology Services at Gangnam SWOMAN | Thread Lift + Precise Filling for Defined Contours – Only 2 Onda Machines Available in All of Korea, Delivering a Natural Look Without an Overly Plastic Face

Let’s get straight to the point: Sia CLINIC in Gangnam is a Dermatology practice located in the Gangnam Station area of Seoul that specializes in “contour anti-aging” treatments. It focuses on thread lifting and precise contouring performed by its chief physician, and even boasts two of the only Onda microwave body sculpting devices available in all of Korea. This clinic has a clear philosophy—improving sagging and facial contours while achieving a natural, subtle look, avoiding the overly artificial appearance often seen among internet celebrities. Below, we’ll provide you with the address, booking procedures, actual prices for services at Sia CLINIC in Gangnam, along with four key factors to consider before making a decision.

II. Why did I write about Gangnam Sia Dermatology? An Onda device helped me understand this clinic better.

I first came across Gangnam’s Sia Dermatology because it advertised the use of Onda microwave body sculpting devices — just 2 of which exist throughout all of South Korea. Onda has been the most popular body sculpting device in South Korea over the past couple of years, and Sia Dermatology in Gangnam uses it as one of its key tools for shaping and anti-aging treatments. This alone shows that they don’t aim to follow a one-size-fits-all, generic approach to medical aesthetics.

Onda is neither an HIFU nor Thermage. It’s the Coolwaves microwave body sculpting system developed by the Italian medical equipment manufacturer DEKA, utilizing 2.45GHz microwaves to target the subcutaneous fat layer, thereby breaking down excess fat while simultaneously tightening the skin. In contrast, HIFU and Thermage focus primarily on skin tightening and lifting. By including Onda in its treatment menu, Gangnam’s Sia Dermatology allows patients to address both fat reduction and skin tightening in the same session.

Another reason why I’m willing to write about Sia’s Dermatology clinic in Gangnam is its aesthetic approach. The clinic emphasizes “natural restraint, avoiding the look of a social media celebrity.” Whether it’s thread lifting or precise contouring, everything is aimed at one goal: restoring lost contours and boosting weakened bone structure, rather than turning the face into something entirely different. For those who worry about not being recognized after treatment, I think this approach is particularly worth noting.

III. How to Make an Appointment at Gangnam Sia Dermatology? 5 Steps from BeautsGO to in-person Consultation

Sia Dermatology in Gangnam is particularly welcoming to international patients, with clear processes for making appointments and visiting the clinic. The appointment process at Sia Dermatology can be broken down into 5 steps, from locking in a time slot online to post-treatment follow-ups. There’s a dedicated person to assist you at each stage, so even if you don’t speak Korean, you won’t encounter any difficulties.

1. Online booking: Use the Chinese interface of BeautsGO to check the schedule and current prices at Gangnam Sia Dermatology, so you can secure a time slot for your visit.
2. On-site registration: Go to the counter on the 4th floor at Gangnam Central Plaza to confirm your appointment, where a staff member who speaks Chinese will assist with the registration process.
3. Personal consultation with the director: The director determines the number of threads to use for thread lifting, the areas to precisely fill in for bone contouring, and the energy dosage for Onda, based on the degree of relaxation, bone structure, and fat distribution.
4. Treatment and Verification: Before the procedure, the probe and treatment agents are opened in person, and the batch number is shown. Both Onda and ultrasound-based treatments record the energy output (in kJ or pulses).
5. Post-surgery notes: Patients receive a checklist with instructions, and Gangnam Sia Dermatology offers follow-up care and consultation recommendations.

IV. Is Sia Dermatology in Gangnam expensive? How much does thread lifting, precise contouring, and Onda treatment cost?

Let’s start with the mechanism before discussing the cost. Thread lifting involves inserting absorbable PDO threads beneath the skin. The barbed threads provide immediate mechanical lift, pulling sagging tissues back into place. As these threads are gradually absorbed by the body over 6 to 8 months, they continuously stimulate the production of collagen and elastin, resulting in effects that typically last between 12 to 18 months. Gangnam’s Sia Dermatology specializes in this thread lifting technique, offering the dual benefits of immediate lifting combined with long-term skin rejuvenation.

Precise bone contour augmentation involves injecting fillers or collagen-enhancing materials deeper into the periosteal layer to restore structural support for the cheekbones, lower jawline, chin, and temples, thereby creating defined contours based on natural bone structure rather than just superficial volume buildup. At Gangnam Sia Dermatology, thread lifting combined with precise bone contour augmentation is used—lifting the skin first followed by reinforcing its structure, which is what underpins their “naturally subtle” aesthetic results.

At Gangnam Sia Dermatology, the number of sessions, dosage, and Onda energy levels are customized based on individual needs, and must be determined by the clinic director after a personal consultation. The table below shows the publicly listed prices for various treatment packages at Gangnam Sia Dermatology on the BeautsGO platform; all prices are in South Korean won as specified by the clinic.

V. Is Gangnam’s Sia Dermatology worth visiting? These 4 key factors determine everything

• Focus Point 1｜Personal Care by the Director, No Assembly Line Process: At Gangnam’s Sia Dermatology, treatments are performed personally by the director. Procedures such as thread lifting and precise contouring rely on the doctor’s skill and understanding of facial anatomy—delegating these tasks to an assembly line approach carries significantly higher risks.
• Focus Point 2｜Aesthetics Means “Natural Restraint”: The goal at Gangnam Sia Dermatology is to restore lost facial contours to their original state, rather than reshaping the face into something entirely different—perfect for those who are worried about not being recognized after treatment.
• Focus Point 3｜Scarcity of Equipment: Sia’s Dermatology clinic in Gangnam has installed the Onda microwave body sculpting device, one of only two units available throughout South Korea. This offers a significant advantage for those looking to address both localized fat deposits and skin laxity at the same time.
• Focus Point 4｜Transparent Pricing with Pre-Comparison Options: The package deals offered by Sia’s Dermatology in Gangnam are listed openly on BeautsGO. Starting from NT$3,600 for basic packages, the full-face anti-aging treatment package costs around NT$94,300—allowing you to plan your budget accurately before making a decision.

When considering these four factors together, Gangnam Sia Dermatology is a better choice for readers aged 28 to 40 who want to improve sagging skin, restore facial contours, and maintain a natural look. If what they’re after is a dramatic transformation in just one treatment or an extremely low price, the customized pricing approach offered by Gangnam Sia Dermatology might not be the most cost-effective option.

VI. Common Questions at Gangnam Sia Dermatology: The 5 Things Hong Kong and Taiwan Readers Most Want to Know

Q1: Can I make an appointment at Gangnam Sia Dermatology even if I don’t speak Korean?

Sure. At Gangnam Sia Dermatology, you can check prices and book appointments through the BeautsGO Chinese interface. Upon arrival, a staff member who speaks Chinese will assist with registration, and an interpreter will be provided during the consultation, so you don’t need to bring Korean with you.

Q2: Will you look swollen to the point of being unrecognizable right after a thread lifting procedure?

Frown line lifting is considered a minimally invasive procedure. Common side effects include swelling and mild tightness, which usually subside within 1 to 5 days. Most people can resume wearing makeup just a few days after the treatment. Sia’s Gangnam Dermatology clinic provides patients with a post-procedure care guide, recommending that they avoid strenuous exercise and saunas for 48 hours.

Q3: What are the differences between Onda, HIFU, and Thermage? Which one is better?

The three devices target different layers of the skin. Onda uses microwaves to target the subcutaneous fat layer, focusing on fat reduction and skin tightening; HIFU and Thermage primarily aim at lifting and firming the skin. At Gangnam Sia Dermatology, a common treatment approach is to combine Onda with HIFU and Thermage. For example, the package that includes 300 shots of the second-generation HIFU at ₩1,190,000 plus Onda at 30kJ offers both fat reduction and lifting effects.

Q4: What’s the difference between precision filling for bone contours and regular Filler?

Bone-based contour fillers are injected at deeper levels of the periosteum to restore structural support for the cheekbones, lower jawline, and chin; regular fillers, on the other hand, are typically used to add volume at shallower layers. At Gangnam Sia Dermatology, specialists first assess the bone structure before determining the appropriate areas and dosage, which means customized quotes are provided and require an in-person consultation for final confirmation.

Q5: What are the business hours at Gangnam Sia Dermatology? Is it open on Sundays?

Gangnam Sia Dermatology is open from 10:30 to 20:30 on weekdays, and from 10:30 to 18:30 on Saturdays, Sundays, and public holidays. The only days off throughout the year are Lunar New Year and Mid-Autumn Festival. There is usually a high volume of customers on weekends, so it’s recommended to book an appointment through BeautsGO before heading there.
