    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.

    MiK Wrinkle & Square Jaw Botox

    I was worried about parking since it's near Gangnam Station, but I didn't have to worry about that, and the nurses were really kind. It's a popular place, so there were a lot of customers. As time goes on, I can tell my nose bridge looks higher and the wrinkles on my forehead have disappeared. I recommend this place!!

    Through the consultation, where everything was explained in an easy-to-understand way, I was able to overcome much of my fear of wrinkle treatment. I was also glad that I could have the procedure with minimal pain thanks to anesthesia.

    I completed my underarm hair removal and jawline botox procedure. I had an appointment for Saturday at 4 PM, but there was a really long wait and I waited for over an hour. There were complaints about the long wait from several patients, and the hospital explained that there are only two doctors and many procedures, which is why the wait is so long.

    I just got Shrink Universe, Inmode, and jawline Botox done. It didn’t hurt at all, and since I had a reservation, there was no waiting time, but everything was pretty much self-service... even cleaning off the numbing cream. I get it’s cheaper than other clinics; I just hope I get good results.

    I really thought about whether to get square jaw Botox for a long time, and finally, I decided to go for it. I have a habit of clenching my teeth, so my jaw muscles are quite developed, and it always bothered me that my lower face looked wide in photos. Especially when I smile or exert myself, my jaw looks even more angular, and I've often heard that my face looks strong overall. When I went for the consultation, the doctor personally felt my jaw muscles and explained that Botox tends to work better for muscle-type square jaws like mine. The procedure itself was really quick. I received a few injections on both sides of my jaw, and it was just a bit of a sting, so it wasn’t too painful. They gave the injections in a way that didn’t hurt, which was nice, and they were friendly too.

    Consultation for square jaw and body Botox event. I received the Rejuvenation and skin Botox treatment for the first time due to sagging skin and enlarged pores as I age. The staff provided detailed explanations and were all very kind, and the doctor was great at alleviating pain during the procedure, for which I am very grateful. At first, I was in pain and scared, but now I feel brave enough to do it again next time.

    This is the clinic I always go to for Botox on my forehead and jawline. No matter where I go or what type of Botox I get, the effects last about 3 to 4 months, and I don’t experience any side effects, so I prefer to go somewhere nearby. Since it's a chain, the doctors change often, but since these procedures don't require any special skills, I'm generally satisfied. Everyone is friendly, and it's conveniently located, so I keep coming back here. After about two days, I start to see the results. My forehead looks smoother, preventing wrinkles, and for my jawline, I feel a bit of discomfort when chewing hard food because of the masseter muscle. But if that muscle gets tight, it can cause sagging and affect my jawline, so I get this treatment regularly as a preventive measure. The ingredients dissipate over time, so I've been getting Botox for over 10 years without worrying about side effects.

    I was concerned about my cheeks and jawline, so I got 300 shots of Shrink along with Botox for my square jaw and salivary glands. Before the treatment, I was worried about pain, but it was more bearable than I expected, and the procedure didn't take long, so I was able to get it done without any stress. Right after the treatment, I only felt a slight numbness, and it didn't interfere much with my daily life. It's not been long yet, but I feel like my facial lines are a bit more defined, and my jaw area looks lighter. Especially since I did both the square jaw Botox and the salivary gland Botox, I'm looking forward to my lower face becoming naturally slimmer. I think this is a good combo for those who want a natural contour improvement rather than an overly noticeable change. I'm planning to monitor the results over the next month as the effects are expected to show more.

    I tried getting Square Jaw Botox + Salivary Gland Botox in a single session, and it worked pretty well! My salivary glands weren’t particularly enlarged to begin with, but I heard the treatment could still be effective, so I decided to try it. I was worried that my face looked generally large, especially around my square jaw, so I got Salivary Gland Botox. The procedure was simpler than I expected, and it didn’t cause much inconvenience in my daily life. I liked seeing the area around my jaw gradually look more naturally defined over time, and I’m really happy because my facial line looks prettier than before in profile and in selfies. I’m satisfied that my jawline looks cleaner in photos than it did before. It was a good treatment to try without feeling too burdened. Definitely a place I’d go back to next time!

    After getting Botox for my square jaw, I'm really happy with how much more defined my jaw looks. I didn't have high expectations for the results, but I was surprised by the changes after the treatment. I was really worried about my jaw muscles, but this has solved my issue. The doctor was also friendly and explained everything well, and the staff were really nice, which made the whole experience very comfortable. I also got hair removal done on my lower face, but that requires multiple sessions, so I'm in the waiting phase. I'll see you in a month!

    I came here for chin Botox because my double chin was too serious. I had it done with a domestic core toxin that has low resistance. They actually recommended Inmode FX for the double chin, but I really didn't want to try it because I thought it would cause too much redness on my sensitive skin. So I went with Botox instead. They offered a good price, so I got it done at a great value, haha~ This hospital is the only one open until 5 PM on Saturdays, and they’re also open until 8:30 PM on weekdays, which is great because I can go after work, haha. My boyfriend also got chin Botox and permanent laser hair removal here, and the prices are very competitive compared to other skin clinics!

    It is definitely a factory-like operation, but it's just that the processing is quick, and it doesn't feel completely negligent. (+ Even though it's just a light jawline Botox... I was a bit disappointed that they didn't even put a bandage on the injection site..ㅜ ) I guess I’ll have to wait to see the effects~

    I recently felt like my face was looking wider, so I got Botox for my jawline at Tox & Fill. During the consultation, they first checked the condition of my jaw muscles and explained that since my muscles were somewhat developed, I'd be able to see results. The procedure itself was quick, lasting about 10 minutes, and using a numbing cream made the pain surprisingly mild. Immediately after the procedure, there wasn't any noticeable change, but after about 12 weeks, my jaw muscles have gradually reduced, and my face has started to look slimmer than before. Jawline Botox works by relaxing the jaw muscles to create a slimmer appearance, and typically, the effects last for about 36 months. Overall, the procedure was quick, and the recovery time wasn’t long, so I felt comfortable undergoing it, and I'm considering a re-treatment for maintenance.

    I received square Botox and Inmode FX treatment at Vands Clinic 😊 Overall, I was really satisfied! Thanks to the square Botox, my chewing muscles relaxed naturally and the contours of my face softened a lot, which I prefer since it’s not overdone. My jawline looks clean and the natural effect is amazing ✨ Inmode FX was especially effective on my jawline and double chin. I felt a nice tightening of the skin, and the lifting effect was definitely noticeable. Even right after the treatment, my face looked more defined 🔥 Vands Clinic is always friendly and explains everything in detail, so I felt reassured during the procedure. I’m truly satisfied with the results and I would 100% visit again! Highly recommend 💯

    I got Masseter Botox. I had it done last May and was happy with the results, so I came back for another treatment. I made a reservation through Naver, and even though I arrived earlier than my appointment time, I was able to pay and get the procedure done right away without waiting. The doctor seemed to be different from last time, but it hurt much less than before, so I was soooo happy. (It might have been because they applied an ice pack, though hahaha.) Anyway, I think Masseter Botox is great because getting it regularly helps manage your facial shape and prevent overuse of the jaw muscles. I’m planning to come back for another treatment in 3–4 months. Oh, I got Goretox again this time too. Hopefully I won’t develop resistance to it in the future.

    It's been a while since I had square jaw Botox done. I've been coming in every 5-6 months as recommended, and I decided to visit after seeing a promotion text. The clinic is calm and smells amazing, and the doctor is very kind, making the treatment comfortable for me haha. I used to just go wherever for cheap Botox, but at some point, I started to worry about my facial sagging and realized that I really need to go to a skilled doctor who can artistically design even square jaw Botox. I felt that strongly again. The doctor administered the injections carefully without pain, and now I'm very satisfied and keep coming back to Abiju haha!

    I got Masseter Botox here today. I wasn’t sure whether I was supposed to apply the ice myself or if the staff would do it, and in the end, we went ahead with the Botox without applying any ice. It was a little prickly, but more tolerable than I expected. I had a consultation with the consultant before going in, and they recommended a treatment that suited me well! I hope the results show up quickly~

    I've always been bothered by my jaw muscles being a bit overdeveloped, making my face look a little angular, so I visited Tox & Fill for a square jaw Botox consultation. I’ve wanted to get this done for a while because my jaw muscles stand out when I laugh or clench my teeth. When I arrived at the clinic, they first checked the condition of my facial muscles during the consultation, and they explained in detail that square jaw Botox helps to reduce the strength of the jaw muscles to make the facial line appear smoother. They recommended a treatment that allows for a natural change rather than going overboard, and they carried out the procedure with an appropriate amount of Botox. The treatment time was shorter than I expected, and it was a simple injection so I was able to go through with it without much stress. After the procedure, I was advised to avoid excessive massaging or hard foods on the same day. I don’t see a dramatic change right away, but I’ve been told that over time, my jaw muscles will gradually shrink, leading to a more natural facial line, so I'm looking forward to it. If you're concerned about a square jaw, I think consulting with Tox & Fill would be a good idea.
