    I feel like the effects are minimal, but I think I'm starting to see my face getting a bit slimmer. The manager was also kind, and I will definitely come back next time!

    This is my second visit. Please provide a friendly consultation. The price events are always great, so I received treatment at a really low cost. I am using ice packs for pain relief in the treatment area, but the effect isn't very significant. Last time I was given coffee, but that service was not available this time. I plan to come back in 5 months. ^^

    The new building is clean and spacious, which is great. Typically, skin clinics suggest a lot of other treatments during the pre-procedure consultation, but I really appreciated that they only focused on the scheduled procedure. I also noticed they have a few menu items to order like a coffee shop while waiting. I received a refreshing coffee as a complimentary service, and my first impression was very positive. I switched clinics for this event to get chin Botox, and I think I’ll be visiting regularly from now on. ^^ Also, there was an amazing first-visit discount, so I received the treatment for much less than the event price. What a bonus! The results are not fully visible yet since it hasn't even been a month, but I received the full dosage, so I expect noticeable changes in two months. Overall, highly recommended!

Photos may look different depending on shooting conditions, and results vary from person to person even with the same procedure. The text shown with a photo is an excerpt from that review; the full text is in the review section.

    I got Masseter Botox! After watching a doctor on YouTube say that Xeomin works well, I decided to stick with Xeomin from now on to get the best value for my money haha. It barely hurt, and I was able to get right back to my daily routine, so I’m completely satisfied!

    First of all, the staff was friendly, which was great. They were kind both during the phone consultation and when I visited the office. I've heard the effects take about three weeks, so I'm looking forward to it.

    I was looking for a hospital due to my parents' upper eyelid surgery and visited based on recommendations from those around me. They carefully explained the surgical method and precautions, which was great. The doctor and all the staff were very kind, so I would consider returning.

    I got 50cc of Masseter Botox (25cc on each side). They didn’t tell me the name of the doctor in charge, but they gave me detailed instructions to avoid saunas, massages, and things like that for a week. I had it done somewhere else last summer, and even though it’s only been a year, the staff here are much kinder.

    It’s been two weeks since I got Botox in my jaw, and the results are amazing. I got it because I was stressed about my square jaw, but they applied numbing cream beforehand, so there was barely any pain. My previously blunt-looking jawline has become slimmer, and my overall appearance definitely looks more refined. People around me have even asked if I’ve lost weight, so I’m extremely satisfied! I haven’t had any side effects, and I plan to keep getting it regularly. Highly recommend!

    The doctor is really thorough and does the treatment very well. On top of that, the prices are very reasonable, and I’m getting treatments that I’m really satisfied with. I’m currently getting Pico Toning MLA and Botox treatments. My forehead wrinkles, frown lines, and square jaw were pretty severe, but they’re improving a lot. The best!

    The jawline was well-defined, but as the facial fat reduced, it became more pronounced. With square jaw Botox, the jawline has also softened.

    The square jaw Botox is less painful than I expected. I'm hopeful about the results, and it's now the second week, and I'm starting to see a slight reduction in my jawline.

    I got Botox for my square jaw and my nostrils, and both were less painful than I expected. I knew what to expect with my jaw since I've had it done before, but the nostrils were actually more bearable than I thought.
