    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 regularly get Botox for my jawline, and I happened to catch a promotion at the Gwanggyo branch. After a friendly consultation, the female doctor came in and explained how she would divide the injections by area. Since I'm in my 50s, I was particularly concerned about my wrinkles. She mentioned that if the forehead injections are placed too close to the eyebrows, it could make my eyes feel heavy, so I opted to have them injected as close to my hairline as possible. As for the jaw Botox, I was worried about my cheeks sinking in, so I had it injected as far back as possible.

    I had Botox for my frown lines and forehead wrinkles. I used domestic Botox for the treatment, and I was really worried about my wrinkles, so I regret not doing this sooner. They say you should take care of your wrinkles in advance.

    I had Masseter Botox and Dermal Filler in the tip of my nose (the tip normally can’t be filled because there’s no supporting structure, but the doctor shaped it as naturally as possible using 1 cc). At first, it immediately gave me a straight nose, but they said it would gradually settle and look more natural as the swelling went down. They applied numbing cream for both treatments, so it didn’t hurt at all. What I liked most was being able to consult directly with the doctor and the comfortable, friendly care! (I don’t like factory-style clinics! I don’t want to consult with a clinic coordinator!)

    I was really nervous and worried about getting Botox for the first time on my square jaw, forehead, glabella, and around my eyes, but the person who performed the procedure was very skilled and thorough, which made the experience much more comfortable than I expected. There was almost no pain during the process, and I was especially pleased that I could return to my daily life right after without any swelling or significant discomfort. I did get a little bruising from the injections under my eyes, but since I naturally bruise easily, it didn’t bother me much and it’s healing naturally. Most importantly, the jawline improvement I was looking forward to started becoming visible about a week later, which increased my satisfaction even more. I had been worried because my jaw muscles were quite developed, but now my face looks noticeably softer and slimmer, and it makes me happy every time I look in the mirror!

    I've been really troubled by how wide my face looks because of my square jaw for a long time. After looking into various options, I decided to go with Botox because it was simple and the recovery seemed quick. The procedure at the clinic took only about 10 minutes and the pain was just a little prick when they injected me. Right after the treatment, my jaw felt a bit stiff and slightly swollen, but it didn't interfere with my daily activities at all. About two weeks later, I noticed that my jawline had become smoother and my face looked slimmer. By the fourth week, the results were really noticeable, and my face shape appeared much more natural in photos. However, I did feel like I had a bit less strength when chewing tough foods. They say the effects last around 5 to 6 months, so if I'm satisfied, I might consider getting it done again. Overall, it was a simple procedure that definitely made a noticeable change, so I'm very happy with it. I think it could really help anyone who's struggling with a square jaw.

    I had Glabellar Botox, Alar Botox, Masseter Botox, and a Facial Contouring Injection with Dr. Jo Hyun-jong, and I was really satisfied overall! 😊 From the very first consultation, he carefully examined the areas I was concerned about and explained things while considering the balance of my entire face rather than just recommending a lot of treatments, which made me trust him. He also explained each step during the procedures, so I was able to relax and receive them comfortably. The glabella was an area that especially bothered me when I made facial expressions, but it looks naturally smoothed out now. I also like how my nostrils look neater without being too exaggerated. After getting the Masseter Botox and Facial Contouring Injection as well, my face looks softer and slimmer than before, so I was happy with how I looked in photos too. I liked it even more because the change looks natural rather than overly obvious. Most of all, Dr. Jo personally examined everything so carefully and explained everything so kindly that if I ever get another treatment, I would want to return to Dr. Jo Hyun-jong. I would also recommend this place to anyone around me who is considering Botox or a Facial Contouring Injection. I was highly satisfied overall, from the consultation through the procedures! I’ll be back again next time 😊

    I stopped by in a hurry while my child was at academy because you were running a promotion. Forehead Botox for only 10,000 won? Since I was due for it, I guess I’m lucky. The male doctor injected it very carefully! I also wanted to get Botox for my square jaw, but unfortunately I couldn’t because the date didn’t work outㅠㅠ It was over quickly, so I saved time too~ Maybe because it was Monday, I was able to get the procedure done early! I’ve been keeping an eye out for the Skin Botox promotion, and as someone who makes good use of the weekday time-limited events every week, I was really happy with this one! I’m waiting for the Skin Botox promotion! If the clinic had been just a little closer, I think I would have paid for the 10-session Pico Toning promotion tooㅠㅠ I also liked how quickly the nurses got everything moving!

    I had Botox for wrinkles under my eyes and I'm really satisfied. I didn't have high expectations, but I saw results beyond my expectations, which makes me happy. I think I'll keep coming back for treatments regularly. My second procedure at the Mikey clinic was also very satisfying, and I'll definitely keep coming back. ^^

    This is my regular clinic. I usually get Botox fillers during their events, but this time I paid full price since it wasn't during an event. I got Botox for my forehead and between my eyebrows, and the procedure only took a few minutes. It stung a bit, but the doctor and the staff are all really friendly, so even though I've moved to a different area, I continue to come here. I've only been getting Botox between my eyebrows, but this time I got it for my forehead as well. I didn’t have any bruising, just a little swelling, but that went down quickly, and I could go about my day with no issues. The effects usually show up within a week. They pay attention to detail, so I don't have that heavy drooping feeling on my eyelids. The value for money is excellent, so I plan to get Botox for my square jaw next time.

    Guro) Popular Botox Treatment Collection

    I’ve always had more developed jaw muscles than most people, which made my overall impression look a bit harsh and my facial contours seem somewhat rugged, so it had been bothering me a lot. While looking for a dermatology clinic for Masseter Botox, I ended up visiting U&I Clinic’s Guro Branch because it had great reviews and lots of positive patient feedback. As soon as I walked in, I felt good about the place because the interior was neat and clean. The front desk staff welcomed me very warmly, and the wait wasn’t long, so I was able to receive my consultation and treatment smoothly. What I especially liked was how kindly and carefully they explained during the consultation how they could shape my jawline naturally without going overboard, taking into account the structure of a man’s jawbone and the shape of his muscles. During the procedure, they also took care to minimize the pain and worked quickly, so I was able to go through it comfortably without feeling too stressed. If you’re a man who’s concerned about a square jaw or your facial contours, I recommend visiting U&I Clinic’s Guro Branch. Thank you.

    My jawline is developed, making my face angular and close to a square shape. With square jaw Botox treatment, you can achieve an effect as if the bone has been sculpted. A subtle V-line is also possible.

    I frequently visit for jaw Botox treatments. The staff members are friendly, and the doctor is kind! I like that I can get seen without long waits when I have a reservation. There are various types of jaw Botox, but among domestic options, Coretox is good because it has no resistance. At other places, the price can be about double, but Maypure often has promotional rates for the procedure! Before getting Botox, I have to apply a cold pack to both sides of my jaw but the ice numbs the area quickly, so I don't mind holding it there for a bit. Some say jaw Botox is painful, but I find it not too painful at all. Thank you for not making it a painful experience!
