Jawline Slimming with Botox & Dysport

What to Expect – Before, After & Beyond

If you’ve been searching for a non-surgical way to slim your jawline or relieve jaw tension, teeth grinding, or TMJ discomfort, masseter Botox or Dysport may be the solution. At Defy Aesthetic, we use this advanced injectable treatment to both enhance facial balance and improve quality of life for patients dealing with chronic jaw issues.

What Is Masseter Botox & Why It Works

Masseter Botox (often referred to as jawline slimming Botox) involves injecting Botox or Dysport into the masseter muscles — the powerful muscles on either side of the jaw responsible for chewing.

When these muscles are overactive, they can cause:

  • A wider or square-shaped jaw

  • Jaw tension or soreness

  • Chronic teeth grinding (bruxism)

  • TMJ-related discomfort or headaches

By relaxing the masseter muscles, Botox or Dysport helps to:

  • Slim and soften the lower face

  • Reduce clenching and grinding

  • Relieve jaw tension and TMJ symptoms

  • Create a more balanced, contoured jawline

This makes masseter Botox both a cosmetic and therapeutic treatment, which is why it’s become one of the most requested services at Defy Aesthetic.

Masseter Botox for TMJ & Teeth Grinding

Many patients are surprised to learn that masseter Botox is widely used to help manage TMJ dysfunction and bruxism.

If you experience:
• Jaw pain or tightness
• Clicking or popping in the jaw
• Morning headaches
• Worn or cracked teeth from grinding
• Facial muscle fatigue

Botox or Dysport can significantly reduce muscle overactivity, allowing the jaw to relax. While it does not cure TMJ, it can dramatically reduce symptoms and prevent further strain on the jaw joint.

As an added benefit, patients often notice facial slimming as the masseter muscle gradually decreases in size.

Before & After: What Results Can You Expect?

Masseter Botox works gradually, not overnight:

📸 Before: Prominent masseter muscles may give the jaw a bulky or square appearance.
📆 2–4 Weeks Post-Treatment: The muscle begins to relax; tension and clenching often improve first.
📆 4–8 Weeks Post-Treatment: Visible slimming of the lower face becomes more apparent as the muscle softens and reduces in size.

Because the change is subtle and progressive, before-and-after photos are extremely helpful in appreciating the transformation.

Before Your Appointment: How to Prepare

To optimize your treatment and minimize side effects:
✔ Stay well-hydrated
✔ Avoid alcohol for 24–48 hours prior
✔ Avoid blood-thinning medications or supplements if medically appropriate
✔ Let your provider know if you grind your teeth or have TMJ symptoms — this helps customize dosing

Every treatment at Defy Aesthetic is tailored to your facial anatomy and functional concerns.

What to Expect After Masseter Botox

This treatment is quick and requires little to no downtime. After your injections:

✅ Do not lie flat for 4 hours
✅ Avoid massaging or pressing on the jaw area for 24 hours
✅ Skip strenuous exercise for 24 hours
✅ Avoid heat exposure (saunas, hot yoga) for 48–72 hours
✅ Avoid facials or dental work immediately following treatment if possible

Mild swelling, tenderness, or soreness can occur and usually resolves within a few days.

How Long Do Results Last?

Results typically last 3–6 months, depending on your metabolism, muscle strength, and whether you grind or clench regularly.

Patients receiving masseter Botox for TMJ or bruxism often find that consistent treatments lead to longer-lasting relief, as the muscle becomes less overactive over time.

Maintenance treatments are usually recommended every 4–6 months.

You may be a great candidate if you:
