Does getting Botox injections in the jawline really cause facial sagging?

Generally speaking The correct way to inject Botox into the jawline. It won't cause your face to sag because this process reduces muscle size and isn't directly related to skin sagging.

However, some people feel their face is sagging, and here are the reasons:

  • Injecting too much Botox can cause the jaw muscles to atrophy too quickly, resulting in sagging skin that was previously supported by the muscles.
  • In some people with a facial structure that has less fat or thin cheek tissue, when the jawline becomes smaller, they may feel that the skin along the jawline is slightly looser than before.

For cases with excess cheek fat. When Botox is injected into the jaw muscles, the jaw muscles shrink, making the face appear slimmer. but If you already have excess fat in your cheeks, jawline, or chin, some people may notice that the fat in those areas appears "sagging" more than before. In this case, other solutions are needed to manage the fat. Therefore, nowadays, injecting Botox solely to reduce the jawline needs to consider other facial features to determine how beneficial it will be for your overall facial shape.

Instructions before getting Botox injections.

Doctors have observed that many Gen Y teenagers focus so much on having a "slim face" that they overlook other facial details. In reality, achieving a beautiful face isn't solely dependent on jawline contouring or Botox. Skin structure, fat, cheek tissue, and skin firmness all contribute to a "balanced" and attractive appearance in the long term.

Doctors don't want everyone to focus solely on a temporarily smaller face, inadvertently leading to sagging skin, undefined jawlines, or missing crucial issues that should be addressed simultaneously. Therefore, detailed planning with a doctor will help achieve safe and truly attractive long-term results.

The doctor has some advice.

  1. Detailed facial assessment. Before deciding to get Botox injections, the doctor will advise you to consider the amount of fat and the condition of your facial skin.
  2. Adjust the treatment plan. Additional procedures may be recommended, such as:
    • HIFU/Ulthera for skin tightening.
    • Thread lifting helps to lift the skin on the cheeks or jawline.
    • Alternatively, cheek fat can be dissolved along with Botox injections for those with excessive facial fat.
  3. Control the amount of Botox to an appropriate level. Avoid injecting too much, as it can lead to severe muscle weakness. (Doctors often say that injecting a lot doesn't necessarily mean you'll be more beautiful; it only leads to more damage.)

Finally, I want everyone to achieve results that make them feel confident, safe, and beautiful for a long time. If you have any concerns or would like further consultation, I am always happy to provide detailed, personalized advice. 😊
