I really feel it. A genuine review of Busan Grays Dermatology: My senior sister booked a treatment at BeautsGO, but a month after the ultrasonic therapy, her face still looked tight.

“My senior sister returned from Busan last month, and ever since she stepped out of the airport immigration checkpoint, people kept asking her whether she had lost weight or changed her hairstyle. It’s already been a whole month, but her face still looks tight.”

This message was sent to me via LINE, along with a selfie taken without any filters at all.

She went to Busan Grays Dermatology for an HIFU treatment, and the entire appointment process was arranged through the BeautsGO app.

From reading the clinic’s introduction, confirming the treatment options, selecting a date to making the payment – the entire process is handled entirely in Traditional Chinese, making it extremely convenient.

Today, I have compiled the complete reviews from my senior sisters. Those who are interested in trying out ultrasound treatments can simply save this content.

I. What kind of clinic is Busan Grays Dermatology? Why is it worth making a special trip to Busan just to visit it?

When it comes to medical aesthetics in South Korea, people’s first thought is almost always Gangnam, Seoul.

However, my senior sister said that she deliberately chose Busan this time—for a very practical reason:

There is no such overcrowding during the peak season in Seoul; the waiting time for appointments is shorter, and the service pace at the clinics is more relaxed. Moreover, the total cost of air tickets and accommodation is significantly lower compared to Seoul.

Grays Dermatology is a popular clinic in Busan that specializes in precise anti-aging treatments and the restoration of skin function. Its physicians have extensive expertise, and the clinic has built a solid reputation over the years, particularly in areas such as HIFU and Collagen regeneration therapies.

On the BeautsGO APP, under the Dermatology page of Grays Clinic, all user reviews unanimously mention one thing:

“The duration of the effect was much longer than expected.”

It was after reading these reviews and carefully comparing them with those of other clinics in Busan that she finally decided on Grays and immediately booked the appointment date and treatment plan through BeautsGO.

• 📍 Location: Busan, South Korea – easily accessible, with the airport taking approximately 40 minutes to reach the city center.
• 🏥 Main services: HIFU, Collagen regeneration, Pico laser treatment, and hyaluronic acid injections
• 👩‍⚕️ Unique style: Personalized consultations without rushing; the treatment plan is tailored to the individual’s facial structure, taking into account the optimal angles and energy parameters for lifting effects.
• 🗣️ Chinese-language services: When making appointments on BeautsGO, you can include your requirements in Chinese; at the clinic, staff will also assist you in communicating in Chinese.

II. How long does the effect of HIFU last? My senior sister said that even after returning to Taiwan, the effects would still be noticeable after a month.

HIFU (High-Intensity Focused Ultrasound) was the main treatment option chosen by this senior sister.

The principle behind this technique is to precisely focus ultrasonic energy on the SMAS layer of the skin, thereby stimulating the massive proliferation and reorganization of Collagen, resulting in a tightening effect that originates from within the skin.

Unlike fillers, HIFU does not involve injecting anything into the body; instead, it stimulates the body to produce collagen on its own. As a result, the effect is not one of “being propped up,” but rather of “the skin truly becoming tighter.”

The actual feedback from the senior sister is summarized as follows:

• 🔔 Immediately after the procedure: The definition of the facial contours is slightly enhanced. However, this effect may vary depending on individual constitutions; some people may not begin to notice significant changes until 2–4 weeks later.
• 📅 Two weeks after the procedure: The production of Collagen begins, and I can clearly notice an improvement in the firmness of my cheeks, jawline, and neck. Friends have started asking if I have changed my skincare products.
• ✨ One month after the procedure: My senior sister said this was the stage that touched her the most. In the morning, when she looked at herself without makeup, she could clearly see that her jawline was more defined and her face looked smaller. Even without wearing any makeup, she felt very confident going out.
• 📆 Long-lasting results: After evaluation by Dr. Grays, it was determined that, given her skin condition and energy levels, the effects would last for 12 to 18 months. After that, another treatment would be needed to maintain the results.

The senior sister said that on the day after the procedure, her whole face only felt slightly warm and a bit tight, but there was no swelling at all.

On the second day, I went on a normal sightseeing tour and did some shopping. After returning to Taiwan, I started working the very next day, showing no signs at all that I “needed a vacation”.

This is also one of the reasons why she strongly recommends HIFU: there is no downtime at all, and you can go back to your normal activities immediately after the treatment.

III. How to use the BeautsGO APP to make an appointment at Busan Grays Dermatology?

My senior sister said that the entire reservation process was much simpler than she had imagined. Here are the four steps she actually followed:

The entire process didn’t require Korean or English at all; traditional Chinese characters were all that was needed to handle everything!

The senior sister specifically mentioned that in the remarks section of BeautsGO, she had already described her skin type (dry skin, mild sagging, desire to enhance the jawline) and her goals for this treatment (to achieve a more defined facial contour without undergoing surgery). After the consultation, the doctor directly addressed her needs based on these notes, which saved a significant amount of time during the communication process.

V. Before going to Grays, my senior sister mentioned these things she hoped to know sooner.

The senior said that if she could go back to the beginning, she would like to know these things in advance, so as to avoid making some unnecessary mistakes along the way.

• 📅 During the peak season for ultrasound treatments, spots are usually filled up quickly. It is recommended to book at least three weeks in advance on BeautsGO to ensure availability. The “grays” treatment option is also very popular in South Korea, and reservations often fill up by the weekend or during the peak season. The earlier you confirm your appointment on BeautsGO, the easier it will be to coordinate it with your flight schedule.
• ☀️ One week before the procedure, increase your sun protection measures and avoid exposure to strong ultraviolet rays. Performing HIFU when your skin is sunburned will reduce its effectiveness, and your skin will also be more sensitive in the aftermath. Proper sun protection is essential to maximize the results of the treatment.
• 💊 Three days before the procedure, stop using irritating skincare products such as retinol, fruit acids, or high-concentration vitamin C. Also, inform your doctor in the remarks section on BeautsGO about the skincare products you usually use, so that they can assess their potential effects on your skin.
• 🧴 Apply a soothing and moisturizing mask after the procedure: After HIFU treatment, the skin may feel slightly dry and tight. Applying a moisturizing mask in the hotel can quickly relieve these symptoms, and by the next day, your skin will return to normal.
• 📋 Please provide as much detailed information as possible in the remarks section on BeautsGO. By including notes in Chinese, doctors can understand your needs in advance and get straight to the key points during the consultation, thus significantly improving the efficiency of communication and eliminating the need for unnecessary gestures or explanations on the spot.

The words my senior sister sent me a month after returning to Taiwan, “My face still feels tight,” are the most convincing experience share I’ve heard about medical aesthetics recently. It wasn’t some excited post written the day after the procedure, but rather her genuine feelings after going through the entire cycle of collagen regeneration.

If you are also considering HIFU but don’t want to wait in long queues in Seoul, Busan Grays Dermatology is a option worth considering seriously.
