사각턱 보톡스 전후 — 현실적인 변화 시점

Dr. Jong Seon Kim4분 읽기

저는 강남 헤라클리닉 성형외과 전문의 김종선입니다. 국제쁘띠의학회 이사로도 활동합니다. 해외 환자분들이 내원 전 가장 많이 문의하시는 시술이 사각턱 보톡스이고, 메시지마다 같은 질문이 숨어 있습니다. "얼마나 빨리 갸름해지나요?"

사각턱 보톡스는 언제부터 달라지나요?

근육은 3~7일에 이완되기 시작하지만, 눈에 보이는 갸름함은 몇 주가 걸립니다. 이 간격이 혼란을 만듭니다. 보톡스는 근육 수축을 빠르게 멈추지만, 부피 자체는 쓰이지 않는 근육이 서서히 줄면서 빠집니다. 주사 일주일 뒤 사진에는 거의 아무것도 없는 경우가 많고, 그건 실패가 아니라 정상입니다.

이마나 미간 보톡스와 반대입니다. 그쪽은 첫 주에 변화가 보입니다. 턱은 주름이 아니라 부피의 변화이기 때문입니다.

믿을 수 있는 전후사진의 조건

  • "after"가 아니라 주 단위로 표기된 간격
  • 같은 각도 — 3/4 측면은 정면보다 턱선을 더 갸름하게 보이게 합니다
  • 이완된 턱, 어금니를 벌린 상태. 악무는 것만으로 윤곽이 시술보다 크게 달라집니다

헤라에서 진행한 시술의 케이스 기록은 환자 케이스 갤러리에서 시술별로 보실 수 있습니다.

맞는 분과 맞지 않는 분

교근이 발달해 턱이 넓어 보이는 경우에 맞습니다. 이를 악무는 습관이나 이갈이에서 오는 경우가 많습니다. 어금니를 물고 턱 각에서 불룩해지는 근육을 만져 보십시오. 그 불룩함이 고민이라면 이 시술이 다루는 부분입니다.

뼈를 깎지는 못합니다. 하악골 자체에서 오는 넓이라면 보톡스로 달라지지 않으며, 도달할 수 없는 회차를 파는 대신 그렇게 말씀드립니다. 턱선의 처짐도 다루지 못합니다. 그건 탄력의 문제이고 리프팅의 영역입니다.

진료실에서 하는 일

주사는 5~10분입니다. 악물어 달라고 요청해 근육 경계를 확인한 뒤 그 안쪽에 넣습니다. 용량은 고정 메뉴가 아니라 손에 잡히는 근육을 따라갑니다. 헤라에서 보톡스는 전문의가 직접 주사하며 개봉·시리얼·기록 관리 프로토콜을 따릅니다.

다운타임은 최소입니다. 바늘 자국이나 가벼운 발적이 잠시 보일 수 있고, 시술 후 문지르지 않으셔야 합니다.

환자분들이 다음으로 묻는 것

"얼굴이 홀쭉해 보이지 않을까요?"

보수적인 용량에서는 그렇지 않습니다. 아래 얼굴을 꺼지게 만드는 건 과다 시술이고, 제가 적극적으로 피하는 오류입니다. 씹는 데 쓰는 근육을 과하게 잡느니 적게 넣고 다시 보는 편을 택합니다.

"씹는 힘이 약해지나요?"

초기 몇 주간 단단한 음식에서 가벼운 피로감을 느끼는 분이 있습니다. 용량이 빠지면서 정리됩니다.

"얼마나 자주 해야 하나요?"

효과는 대개 3~4개월 지속되며 개인차가 있습니다. 갸름한 라인을 유지하는 건 반복 시술이고, 근육이 한동안 이완되어 있으면 간격이 길어지는 경우가 많습니다.

사진과 거울이 다르게 말하는 이유

거울로는 그대로인데 주변에서 갸름해졌다고 한다는 말씀을 자주 듣습니다. 착각이 아닙니다. 매일 보는 얼굴에는 점진적 변화에 적응하지만, 두 달 만에 본 사람은 그렇지 않습니다. 첫 시술 전에 고정된 각도로 사진을 찍어 두시라고 권하는 이유이기도 합니다. 몇 주에 걸쳐 오는 변화에 기억은 좋은 기준점이 못 됩니다.

낮빛에서 정면과 3/4 측면으로, 어금니를 벌리고 턱에 힘을 뺀 상태로 찍으십시오. 4주와 8주에 같은 조건으로 반복하십시오. 그 세 장이 어떤 병원의 갤러리보다 많은 것을 말해 줍니다.

두 번째 회차가 달라지는 이유

첫 회차는 수년간 열심히 일해 온 근육을 이완시킵니다. 두 번째 회차를 근육이 완전히 회복되기 전에 넣으면 대개 첫 회차보다 깔끔한 라인이 나옵니다. 한 번으로 판단하신 분들이 스스로 이 시술을 과소평가하게 되는 이유입니다.

솔직한 한계

유지하는 시술이지 영구적이지 않습니다. 근육의 크기와 힘이 사람마다 달라 결과도 다릅니다. 같은 유닛을 두 얼굴에 써도 같은 사진이 나오지 않습니다. 그리고 이갈이가 원인이라면 습관을 그대로 둔 채 근육만 다루면 더 빨리 돌아옵니다.

시술 자체의 임상 정보 — 적응증, 진행 방식, 회복, 솔직한 한계 — 는 알러간 보톡스 페이지에 정리되어 있습니다.

FAQ

자주 묻는 질문

  • Q1When will I see masseter botox results?
    The muscle relaxes at three to seven days, but visible jaw slimming takes weeks because the bulk shrinks gradually as the muscle goes unused. A photo taken one week after injection usually shows very little, and that is normal.
  • Q2How long does masseter botox last?
    Effects generally last about three to four months and vary by individual. Intervals often lengthen once the muscle has been relaxed for a while.
  • Q3Will masseter botox make my face look gaunt?
    Not at a conservative dose. Hollowing of the lower face comes from over-treatment. I would rather place less and review you than overshoot a muscle you use to chew.
  • Q4Can it narrow a wide jawbone?
    No. Botox reduces muscle bulk, not bone. If your width comes from the mandible itself, I will tell you at the consultation rather than sell you a series that cannot reach your goal.
  • Q5Does chewing become weaker?
    Some patients notice mild fatigue with hard foods during the first weeks. It settles as the dose wears down.

I recently visited Hera Gangnam for a more intensive lifting treatment, and I couldn't be happier with the experience. As someone who had only done basic toning and hair removal before, I was incredibly nervous about trying actual "lifting" lasers, but this clinic put me completely at ease. ​What sets Hera apart is their thoroughness. I had two separate consultations: ​Consultation Manager (상담실장님): She was incredibly kind and helped map out my concerns without being pushy. ​Head Doctor (원장님): He provided a deep dive into the technical side, ensuring I understood exactly how the treatments would work for my face shape. ​I focused on two specific areas to tackle my double chin and overall facial contour: ​10Thera Lifting: A game-changer! The procedure was much more comfortable than I expected. It does hurt a lot but apparently not as bad as Ulthera. The staff members and the doctor would check on me the whole time to make sure the treatment is not too awfully painful. ​Sok-Pae Injection (쏙빼주사): Targeted specifically at my double chin area. ​ ​The entire staff is knowledgeable, professional, and most importantly, they actually listen and care for my needs. I’m already seeing a difference (I might need two more sessions in a couple of months) and am definitely coming back for my forehead and jaw Botox next time! ​Highly recommended if you're a "lifting newbie" looking for a trustworthy clinic in Gangnam.

I recently visited Gangnam Hera Clinic for a Titanium Lifting treatment, and the entire experience genuinely exceeded my expectations. The staff were incredibly warm and welcoming, immediately putting me at ease the moment I walked in. They explained every part of the procedure clearly and thoroughly, making sure I knew exactly what would happen and how to prepare. Although I’d heard that lifting treatments can be uncomfortable, this one was surprisingly manageable. The doctor checked in with me constantly and even took short breaks to make sure I wasn’t feeling any pain, which I really appreciated. The whole process was smooth, well-organised, and very professional. I could tell they were attentive and meticulous from start to finish. The clinic itself is spotless, modern, and honestly one of the best I’ve visited in Seoul!

💖 Visit to Hera Gangnam Clinic: Absolutely Recommended! I visited the Hera Gangnam Clinic today and was pleasantly surprised by how friendly and accommodating everyone was—from the staff and doctors right up to the boss. I received excellent consultation because I wanted to get lip fillers, and achieving symmetry was especially important to me. The attending physician held a very detailed consultation with me and fulfilled all my wishes perfectly. I am super satisfied with my lips already and can hardly wait to see the final result once the swelling has gone down. I will definitely be back! I wholeheartedly recommend this clinic to all foreigners coming to Korea. The entire team speaks several languages, so you don't have to worry about not being understood.🙌🏻

I recently tried the Rejuran treatment at Gangnam Hera Clinic, and I honestly had such a great experience. Before starting, the doctor carefully explained everything to me and recommended the version of Rejuran that would suit my skin best. I had heard that this treatment can be quite painful, but honestly, it was completely manageable. The staff was incredibly warm and welcoming from start to finish. They checked on me throughout the process and made sure I felt comfortable the entire time. The follow-up was also really professional, and they made sure I understood how to take care of my skin afterwards. Overall, I really recommend Gangnam Hera Clinic if you’re thinking about getting Rejuran. It was a smooth, reassuring, and positive experience. ✨

This was my second time visiting Gangnam Hera after returning from the States, and once again, I’m so impressed. The staff are friendly, professional, and genuinely attentive. The clinic is exceptionally clean and modern, with a relaxing atmosphere that makes every visit comfortable. The prices are very reasonable, but what truly stands out is the quality of care and the amazing results. It’s a top-quality dermatology clinic that I would absolutely recommend to my friends and anyone looking for trusted, high end skincare in Korea.
