Botox for Masseter Reduction: Slimming the Jawline Without Surgery

Introduction

A sharp, contoured jawline is often associated with youth and beauty. But for many, enlarged jaw muscles—called the masseters—can create a square or bulky appearance. At Sculpt Med Spa, we use Botox for masseter reduction to slim and refine the lower face, all without surgery or downtime.

With convenient locations in DTLA and Silverlake, clients can achieve a softer, more elegant jawline close to home.

What Is the Masseter Muscle?

The masseter is one of the main muscles responsible for chewing. Over time, habits like teeth grinding (bruxism), clenching, or frequent gum chewing can cause the masseters to enlarge. This creates a wider, more masculine-looking jawline.

For clients who want a softer, slimmer contour, Botox injections at Sculpt Med Spa offer a non-surgical solution.

How Botox Works for Masseter Reduction

When Botox is injected into the masseter muscles, it relaxes them, gradually reducing their size. This process is called muscle atrophy—it’s safe, controlled, and happens over weeks to months.

The result:

• A slimmer, more V-shaped jawline
• Reduced jaw tension and clenching
• Relief from TMJ-related discomfort for some clients

Treatment Expectations

When Will I See Results?

Most clients notice changes in 4–6 weeks, with full slimming effects appearing by 8–12 weeks.

How Long Do Results Last?

Results typically last 4–6 months. With consistent treatments, the jawline may remain slimmer for longer between sessions.

How Many Treatments Will I Need?

• First-time clients: Expect 1–2 sessions spaced a few months apart.
• Maintenance: Treatments are usually needed twice a year to maintain results.

Benefits of Botox Masseter Reduction

• Non-surgical – no downtime or incisions
• Slimmer, softer jawline – ideal for creating a feminine V-shape
• Relieves jaw tension – often improves symptoms of clenching or grinding
• Quick procedure – treatment takes less than 20 minutes

Who Is a Good Candidate?

You may be a great candidate if you:

• Have a wide or square jawline caused by muscle, not bone
• Grind or clench your teeth frequently
• Want to slim your face without surgery
• Are in good health and over age 18

At Sculpt Med Spa in Silverlake or DTLA, our expert injectors evaluate your facial anatomy to ensure Botox is the right choice for your goals.

Botox for Masseter Reduction FAQs

Is Botox for masseter reduction painful?

Most clients find it very tolerable, describing only a quick pinch. Numbing cream can be applied if needed.

You’ll still be able to chew normally. Some people notice mild weakness when chewing very tough foods, but it doesn’t impact daily function.

How many units of Botox are used?

The number of units varies based on muscle size. On average, 20–40 units per side may be required, but your injector will customize the dose.

Can Botox masseter reduction help with TMJ pain?

Yes, many clients report relief from clenching, grinding, and TMJ discomfort after treatment.

Is the slimming permanent?

No. Results last 4–6 months, and repeat treatments are needed to maintain a slimmer jawline. With regular sessions, results may last longer.
