In addition, the neck may look relatively shorter and thicker, and especially in women, a developed trapezius can make the neck line seem less visible.

If the trapezius muscles become overly developed, body balance can be disrupted, making the posture look like forward head posture or rounded shoulders, which can give a slouched impression.

For these reasons, trapezius Botox, which naturally reduces the trapezius muscles, has become very popular.

Also, for at least 2 weeks after the procedure, try to avoid massages that apply strong pressure.

Maintaining proper posture can help prevent the trapezius muscles from becoming overly developed, and when working at a computer, you should consciously avoid tensing your shoulders too much.

Strengthening the muscles around the shoulders rather than the trapezius can help create a balanced body line, and you should be careful because habits such as resting your chin on your hand or carrying a bag on only one shoulder can cause the trapezius muscles to develop asymmetrically.

If the trapezius muscles become overly developed, the shoulders can look heavy and the neck can appear shorter, changing the overall silhouette.
