사각턱 보톡스 부작용 — 실제로 무엇 때문에 생기나

Dr. Jong Seon Kim4분 읽기

저는 강남 헤라클리닉 성형외과 전문의 김종선입니다. 사각턱 보톡스 후 "뭔가 잘못된 것 같다"며 사진을 보내오시는 경우가 다른 어떤 주사 시술보다 많습니다. 당연한 걱정이고, 안심시키는 말보다 임상적으로 분명한 답이 필요한 주제입니다.

"사각턱 보톡스 부작용"은 보통 무엇을 뜻하나요?

대부분은 제품이 아니라 용량이나 주입 위치의 문제입니다. 교근은 경계가 뚜렷한 큰 근육이고, 주변 근육들은 전혀 다른 일을 합니다. 약제가 그 경계를 벗어나면 웃거나 씹는 데 쓰는 근육에 닿고, 눈에 보이는 문제는 거기서 나옵니다.

환자분들이 실제로 말씀하시는 세 가지

웃을 때 비대칭

입꼬리를 당기는 근육(소근·대관골근)에 약제가 닿았을 때 생깁니다. 용량이 아니라 위치의 문제이고, 효과가 빠지면서 회복됩니다.

아래 얼굴이 꺼져 보임

과다 시술입니다. 교근은 일하는 근육이라 너무 줄이거나 너무 자주 하면 볼이 받쳐 주는 힘을 잃습니다. 더 갸름해지길 바라며 계속 추가하신 분들에게서 가장 많이 봅니다.

씹는 힘이 오래 약함

가벼운 정도로 초기 몇 주간은 정상입니다. 뚜렷한 약화가 오래 간다면 근육에 필요한 양보다 많이 들어간 것입니다.

애초에 어떻게 피하는가

주사 전에 근육을 확인하는 것으로 피합니다. 악물어 달라고 해서 경계를 손으로 잡고, 그 안쪽에 적절한 깊이로 넣습니다. 교근은 깊은 층에 있어서, 얕게 들어가는 것이 바로 주변 근육이 관여하게 되는 경로입니다. 용량은 고정 메뉴가 아니라 만져지는 근육을 따릅니다.

헤라에서는 전문의가 직접 주사하고, 개봉·시리얼·기록 관리 프로토콜을 따르므로 무엇이 쓰였는지 확인하실 수 있습니다.

이미 생겼다면

먼저, 일시적입니다. 보툴리눔 톡신은 대개 3~4개월에 걸쳐 빠지고 비대칭도 함께 회복됩니다. 필러처럼 녹이는 약제는 없으므로 정직한 답은 시간입니다. 그리고 도움이 되는 경우에는 시술한 쪽에 더 넣는 대신 반대쪽을 조정합니다.

정보가 있으시면 가져와 주십시오. 어떤 제품을, 몇 유닛, 언제 넣었는지가 오늘 제가 안전하게 할 수 있는 범위를 바꿉니다.

환자분들이 다음으로 묻는 것

"가짜 제품이었을까요?"

대개는 아닙니다. 이런 사례는 위조품보다 술기로 설명되는 쪽이 훨씬 많습니다. 다만 정품 관리 여부는 어디서 시술받든 확인하실 수 있어야 합니다.

"다시 맞으면 또 그럴까요?"

원인을 찾으면 그렇지 않습니다. 교정 방문에서는 보수적으로 시작하고 경과를 보는 편을 택합니다. 문제를 만든 그 용량을 반복하지 않습니다.

주사를 맡기기 전에 물어보실 것

교정을 의뢰받는 사례의 대부분은 첫 상담에서 세 가지를 물었다면 피할 수 있었습니다. 저에게도 물어보시길 권합니다.

  • "주사 전에 근육을 만져 보시나요?" 사진만으로 계획을 세운다면 경계를 추측하고 있는 것입니다.
  • "용량은 얼마이고, 제 근육에 왜 그 용량인가요?" 진찰 전에 제시되는 숫자는 임상적 판단이 아니라 메뉴 가격입니다.
  • "경과는 언제 다시 보나요?" 보수적인 첫 용량과 재진이 큰 한 번보다 낫습니다. 더할 수는 있어도 뺄 수는 없습니다.

"더할 수는 있다"가 여기서 중요한 이유

필러는 녹일 수 있습니다. 보툴리눔 톡신은 그럴 수 없습니다. 매일 씹는 데 쓰는 근육에서 적게 시작해야 하는 이유가 이 비대칭이고, "이번엔 오래가게 많이 넣어 달라"는 요청을 거절하는 이유이기도 합니다.

솔직한 한계

변동이 전혀 없다고 약속할 수 있는 시술자는 없습니다. 같은 유닛이 두 얼굴에서 다르게 작동합니다. 약속할 수 있는 것은 실제 가진 근육에 근거한 계획, 보수적인 첫 용량, 그리고 한 번에 크게 하기보다 다시 보는 것입니다. 만져 보지도 않은 근육에 결과를 보장하는 곳이 있다면 조심하십시오.

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

FAQ

자주 묻는 질문

  • Q1What usually causes masseter botox to go wrong?
    Dose or placement, not the product. The masseter is deep with a clear border; product that drifts outside it reaches muscles used for smiling or chewing, which is where visible problems come from.
  • Q2Why does my smile look uneven after masseter botox?
    Product likely reached the muscles that pull the corner of the mouth. It is a placement issue and it resolves as the effect wears off, generally over three to four months.
  • Q3Can masseter botox be reversed?
    There is no dissolving agent as there is for filler. The honest answer is time — botulinum toxin wears off — plus adjusting the untreated side where that helps, rather than adding more to the treated one.
  • Q4Why does my lower face look hollow?
    That is usually over-treatment. The masseter is a working muscle; reduced too far or too often, the cheek loses support. It is most common in patients who kept topping up chasing further slimming.
  • Q5Is chewing weakness normal?
    Mild fatigue with hard foods in the first weeks is normal. Persistent, marked weakness suggests the dose was higher than the muscle needed.

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.
