Masseter BOTOX® in Westlake Village and Studio City, CA

Whenever you catch a glimpse of yourself in the mirror, do you ever wish for a more sculpted jawline or feel bothered by the appearance of a broad face? Often, the width of the jaw can be attributed to the masseter muscles, which, when overly developed, can give the face a more square shape. Masseter BOTOX is an innovative solution to this issue, offering facial slimming benefits and relief from jaw tension and habits, like teeth clenching. By utilizing a specialized form of botulinum toxin, this treatment gently relaxes the masseter muscles. This relaxation leads to a subtle but noticeable slimming of the jawline, contributing to a more refined facial silhouette. Moreover, the reduction in muscle activity can alleviate symptoms associated with teeth grinding and TMJ disorders, making it a multifaceted approach to enhancing both your aesthetic appeal and comfort. At Starr MedSpa in Westlake Village or Studio City, CA, our dedicated team is proud to provide this sophisticated treatment, helping you achieve your desired look with precision and care. We're here to guide you through the benefits of masseter BOTOX and how it can be a key component in achieving that defined jawline you've been dreaming of.

During your initial consultation for masseter BOTOX injections at Starr MedSpa, our skilled professionals will perform a detailed evaluation to determine the optimal areas for enhancement. Masseter BOTOX is delivered in a quick and straightforward outpatient procedure, allowing you to receive your injections during the same visit. The treatment involves precisely injecting the botulinum toxin into the masseter muscles using a very fine needle. The process is swift, taking only about 30 minutes, and is generally associated with minimal discomfort, often described as a brief pinching sensation. After your session, you're all set to leave our Westlake Village or Studio City, CA facility and resume your daily activities.

Frequency of treatment: every 2.5 – 4 months

A broad jawline and muscle-related facial concerns not only alter our appearance but can also add to a perception of increased age or stress. Masseter BOTOX injections are often an effective solution for those looking to achieve a slimmer, more contoured facial profile. Choosing masseter BOTOX at Starr MedSpa comes with a host of benefits, including:

  • Quick treatment times: Sessions for masseter BOTOX are often completed within just 30 minutes.
  • Easy upkeep: For those aiming to sustain their new, sleek jawline, follow-up appointments are conveniently short and easily integrated into a busy schedule.
  • Minimal discomfort: The procedure uses an ultra-fine needle, ensuring the experience is more like a quick pinch with little to no pain.
  • No downtime required: The noninvasive nature of masseter BOTOX means you can immediately resume your regular activities post-treatment.
  • Reduced muscle mass: BOTOX can help reduce the size of the masseter muscle, leading to a slimmer, more defined jawline.
  • Reduced clenching and grinding: Masseter BOTOX can help protect teeth and relieve jaw pain or tension headaches.

The spa itself is breathtaking! You feel like your in another world. I have followed Tenley, who owns Starr Med Spa, from previous spas and i wouldn't have it any other way. I was always afraid of looking fake or frozen with getting Botox , but her technique somehow just makes me look 10 years younger. I've done Botox, micro needling and most recently the Revepeel. My skin looks better now in my 30s than it ever has before. Tenley thoroughly goes over everything in detail and shows you exactly what she's doing. Scheduling is always a breeze with Kelly snd she's so knowledgeable about all of the services. If you ever have any post treatment questions they are always there to answer them. Literally look no further I'm for your skincare needs, this place offers it all and more.

Brittney is so thorough in explaining the process beginning to end, aftercare, etc. She is so kind throughout the process and checks in to make sure you are comfortable. I couldn’t recommend or trust someone more with my cosmetic needs and wants! Thank you Brittney and Starrmed Spa! For reference: I have now received a Microneedling treatment, Botox, and Dysport. I am a reoccurring customer of Brittney’s and I absolutely love her!

Alison is the best! I went in with lots of pain because of my TMJ and she was able to give me Botox. I can now chew and all the pain has gone away. She is super knowledgeable and gives honest advice! I will only be coming to her for my services for now on.
