    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!

    YOU&I Clinic Gimpo BranchGimpo) Wrinkle & square jaw Botox

    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. ^^

    YOU&I Clinic Gimpo BranchGimpo) Wrinkle & square jaw Botox

    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 Botox for my square jaw. Before the procedure, I received proper dosage recommendations during the consultation, which helped address my previous concerns about minimal results and side effects like a 'puffy cheek' look. They explained everything very clearly to me. Before the injection, the doctor took another look at me, opened the product right in front of me, and gave me plenty of time to do ice compresses, making it less painful. Other than the consultation area being a bit noisy since it wasn't separate, I didn't find anything else uncomfortable. The waiting area was also pleasant, and the staff was friendly. It's conveniently located near the subway station, making it easy to get to. The waiting time wasn't too long either, so overall, I was very satisfied, and I would definitely consider coming back next time.

    Because it’s conveniently located, I’ve been coming here for over three years whenever I need Masseter Botox or an anti-inflammatory injection, and everyone is always so friendly! I never have to wait long, and after making an appointment and checking in, the treatment starts almost immediately, so I love that I can get it done quickly and be on my way. I’m also satisfied with how the treatments turn out every time! They have lots of promotions, so I can get the same treatments for a little less than at other clinics, which makes it easy to come here without feeling too much of a financial burden. I once went with an acquaintance who was visiting for the first time, and they explained the treatment my friend was getting that day in detail, so my friend felt reassured and was able to go through with it comfortably. I was happy too for no particular reason, haha. I’ll be back again for more treatments and care~

    UnverifiedMaypure Clinic, City Hall Station Branch

    Since the clinic is nearby, I had no hesitation in getting domestic square Botox at the Meipure Clinic near City Hall. After a quick cold numbing, the doctor came in and kindly explained everything before proceeding with the treatment. This wasn't my first treatment, but I appreciated all the explanations from the doctor. It was a bit stingy because it was done on both sides of my jaw, but it was bearable, and they clearly explained all the aftercare instructions as well. The facility was very clean, which I really liked. I had made a reservation, but the wait time wasn't long, so I was satisfied. The numbing and the treatment were both finished in about 10 minutes, so it was great to fit it into my schedule easily. I plan to visit again in 6 months.

    I regularly get Botox for my square jaw. The last time I had the soft wave laser treatment, I loved it so much that I made an appointment for more care. People around me keep asking what I've done because they say my face has gotten smaller~ I wanted to maintain this with ongoing treatments, so I booked right away^^* As expected, since it's known for having great management programs, they have a variety of options, and unlike other factory-style clinics, there are many steps in the treatment process and you can feel that they use quality products~ All the staff are super friendly and skilled!! I'm the type to get fully immersed once I'm in, and I already have healthy skin, but I'm hoping it gets even better! The staff are very kind, and the clinic is clean and nice! The director is very attentive.

    - I had mole removal, Pico toning, and jawline Botox done! I was able to get such a great deal with the first-time visit price! It’s only available until April 6th, so if you need it, hurry and go! - The interior was super clean, which I appreciated! Instead of towels at the washing station, they had hand towels available, which was a nice touch. They even sprayed mist to prevent dryness after washing and not applying anything! Oh! And they had regeneration cream at the reception area, so it was nice to apply it simply after the treatment! - They didn’t pressure me with various recommendations but only suggested what was necessary, which I liked!

    UnverifiedBucheon Dr. Evers Clinic

    I recently got Botox treatment for my jaw and temporalis muscle at Doctor Evers in Bucheon, and I am extremely satisfied. I have a habit of grinding my teeth at night and unconsciously clenching my molars during the day, which has made my jaw muscles feel tight and has caused me frequent headaches. I was really stressed out about my square jawline and the volume on the sides of my head, so I decided to visit the clinic on a friend's recommendation. The hospital had a clean and pleasant atmosphere, and the staff warmly welcomed me. The consultation I had with the doctor before the procedure was particularly impressive. They carefully assessed the overall balance of my face and the condition of my muscle development, advising a natural improvement rather than excessive treatment, which made me feel a deep trust in them. Once I moved to the treatment room, they took great care to apply cooling anesthesia to minimize pain. Thanks to the doctor's skilled hands, I barely felt any pain when getting the injections, and the procedure was completed very quickly. About a week later, I noticed that the heavy pressure I used to feel when chewing was noticeably easing. The grinding symptoms and that persistent tightness disappeared, making my daily life much more comfortable. Now, a month later, the line of my face from my side hairline to my chin is significantly slimmer and smoother. People around me frequently ask why my face looks so small and if I've lost weight. I'm really happy that I've achieved not only the aesthetic effects I hoped for but also relief from pain. I plan to visit regularly for ongoing care.

    I think that for lifting procedures like Ultherapy, who performs it and how is more important than the price, so I visited based on a friend's recommendation. I watched videos of the head doctor’s style and approach beforehand on YouTube, and I found that their emphasis on natural and sophisticated facial contours matched well with what I was looking for, which is why I decided to visit. The consultation was conducted by the head doctor themselves, who carefully checked my facial shape, muscles, and skin elasticity. They explained that combining Ultherapy with Botox for my square jaw would give my face a more natural and refined line, which made me trust their expertise. After the procedure, my jawline was more defined, and overall my face looked slimmer and firmer. I was very satisfied because I felt that I naturally looked younger without an overly tight feeling or artificial changes, while maintaining the original vibe of my face. During the procedure, they continuously checked my condition, which reassured me, and the result met my expectation of feeling ‘pretty without being obvious.’ I would like to recommend this to anyone looking for a natural and elegant facial contour.

    UnverifiedBetterMe Clinic Gangnam Branch

    After considering Botox for my square jaw and glabellar area, I made an appointment and visited Better Me Clinic Gangnam. I was happy that I could go straight in without any waiting, and the clinic itself was very clean and comfortable. The staff guided me kindly, and most importantly, the doctor carefully checked my facial shape and muscle condition before the procedure, then performed it with great attention to achieve a natural result. What I liked most was that it wasn’t handled like a factory-style clinic—they took great care of me with a personalized, one-on-one approach. Even after the procedure, there was no bruising or needle marks at all, so it didn’t interfere with my daily life in any way. I recommend Better Me Clinic Gangnam to anyone looking for thorough care and natural-looking results. I’m 100% planning to come back!

    UnverifiedMaypure Clinic Bucheon Branch

    I received Pico Toning, Meladues, and Botox treatments for my square jaw, eye area, forehead, and glabella~ It's a factory-type clinic, so the prices are cheap, and since the procedures are relatively simple compared to others, I visit here frequently without any discomfort. There are several branches, and I've been to a few different locations, but for some reason, I find the Bucheon branch more comfortable, so I usually go there. The clinic is clean inside, but a downside could be that I have to do my post-treatment care myself... But considering the costs, it's something I have to put up with, I guess. They often have events, so if you plan your treatment around those times, you can get it at a lower price. The parking is spacious, but the narrow corridor going down to the basement level 2 is too tight, so I only park on the first floor. It's quite competitive for parking since the building is large, which is a bit inconvenient..ㅠㅠ

    It's what you'd call a factory-style clinic (?) I got domestic Masseter Botox. You can get it done at a low cost, but it takes an extremely, extremely long time. Since this isn't a treatment you can book separately, you have to register on-site and wait. In the large clinic, you have to go through three different areas: registration, consultation, and the procedure waiting area. Every time you move between those three places, they call your name out loudly, so by about the third time my name was called, I started thinking, “There probably isn't anyone I know among the people waiting here, right?” For numbing, they give you an ice pack, and after you've been rubbing it on for about 5–10 minutes, they call you in. Honestly, the cost is only about two-thirds—or even half—of what other places charge, but it's working incredibly well for me. The person who injects me is different every time I go, and honestly, I don't even get a chance to see their face. That's how quickly it happens.

    I got Botox injections. They recommended getting treatment for both my square jaw and temporalis muscles together, so I decided to do both this time, and I’m more satisfied than I expected. I also liked that during the consultation, they didn’t push all kinds of unnecessary treatments, but recommended only what I actually needed for my current condition. The consultation coordinator explained everything in an easy-to-understand way, so I felt comfortable asking about anything I was curious about before the procedure. The doctor also briefly checked my condition beforehand and was very kind throughout the procedure, so I was able to get it done without feeling nervous. Botox injections can honestly be a little scary, but the doctor was so quick that it was over before I even had time to worry, haha. I also appreciated that they explained the precautions and how to take care of the area afterward. Most of all, they frequently offer promotional events, so the price is relatively affordable, and I visit from time to time whenever I need a treatment. It’s not just that the prices are low—I’m satisfied with everything from the consultation to the procedure, which is why I keep coming back. I hope the results turn out natural again this time, and I plan to come back when I need another treatment in the future!

    I had a raised mole on my abdomen that became swollen and painful after shaving, though it eventually went down. I was wondering if it was okay, so I decided to get it checked out and have it removed if possible, which led me to search for a dermatology clinic. I first looked into clinics near my home, but the reviews for the nearby ones weren’t very good, so I searched for a doctor on the official website of Maypure Clinic first..!! The doctor was a woman, and I personally thought she looked friendly, so I decided to visit. They also had a first-visit promotion for Masseter Botox, so I booked that along with my appointment. When I first checked to make a reservation, the earliest available time was 10:00 (or maybe 10:30), so I thought everything else had already been booked, but it turns out they open a little later than usual?! Even though I had an appointment, there was still a bit of a wait, which was disappointing. Since it was my first visit, though, I spent the time looking through the brochures and checking out the inside of the clinic. First, I met the staff member who consulted with me, then the person who disinfected the area, and finally the doctor. She said the raised mole wasn’t a problem, and since the removal cost felt a bit burdensome, I ended up just getting Botox and leaving. They said the results would appear after four weeks, so for now I’ll wait and see how it works !!

    I got Botox for my square jaw and prominent cheekbones at Dayview Dermatology yesterday, and overall, it was a really satisfying experience! I’d been worrying that the developed muscles around my jaw joints and prominent cheekbones made me look a bit too harsh, so I feel much more relieved now that I’ve finally had the treatment. First of all, because the clinic is in such a busy downtown area, I was a little worried about driving there. Parking in this area can be absolute hell, so I was nervous that I might have to wander around looking for a public parking lot. Fortunately, Dayview Dermatology gave me several parking options to choose from, which made visiting by car really easy. Being able to visit comfortably without the stress of parking was a huge plus in the middle of my busy everyday life. Once I went inside, the doctor and the clinic manager conducted a very thorough consultation. They carefully assessed the structure of my facial features and the condition of my muscles, and promised to use precise amounts to create a natural, not overdone contour, which made me trust them right away. During the procedure, they also paid close attention to cooling and numbing to minimize the pain, so I was able to finish much more comfortably than I expected despite being nervous. Since it’s only right after the treatment, I have just a little numbness, but it isn’t interfering with my daily life at all. Thinking about how my muscles will gradually shrink over the next few weeks and settle into a softer facial shape already makes me look forward to checking the mirror. If you’re looking for a clinic that’s easy to get to in a busy area, has convenient parking, and is thorough and skilled, I’d really recommend Dayview Dermatology!
