Introduction

A wide or square jawline is often the result of hypertrophic masseter muscles — the powerful muscles on either side of the jaw that control chewing. When these muscles are overactive due to habits like chronic teeth grinding, gum chewing, or eating hard foods, they can enlarge over time. This not only creates a broader jawline but may also lead to excessive tooth wear, jaw tension, and chronic pain.

At Timeless Regenerative Medicine, we offer Botox® injections to the masseter muscles, a proven and effective solution to both slim the lower face and relieve discomfort. By carefully relaxing the masseter muscles, we help restore balance, comfort, and a slimmer facial contour.

How It Works

Botulinum toxin works by temporarily blocking the nerve signals that cause the masseter muscles to contract. Once injected into the masseters, the muscles gradually relax and decrease in size. As a result, the jawline appears slimmer and more refined, while symptoms such as pain, clenching, or tension are alleviated. Over time, consistent treatment can lead to long-term improvements in both function and appearance.

What It Treats

Masseter Botox is primarily indicated for two concerns. The first is jawline slimming, where overdeveloped masseter muscles make the face appear wide or square. The second is functional relief, addressing chronic pain, headaches, or excessive teeth wear caused by jaw clenching and grinding (bruxism). Many patients notice a combination of aesthetic and therapeutic benefits, making this treatment both cosmetic and functional.

Treatment Experience

The procedure is quick, usually taking no more than 15–20 minutes. During your visit, one of our specialists will carefully map the masseter muscles and administer small, precise injections of Botox®. Most patients describe only mild discomfort, similar to a pinprick. Anesthetic is generally not required, and you can return to normal activities immediately after treatment.

Safety and Results

Botox® for masseter reduction is a non-surgical and minimally invasive treatment. Side effects are typically mild, such as minor swelling, redness, or tenderness at the injection site, which resolve quickly. Results are not immediate; it generally takes 2 to 4 weeks to begin noticing changes, with continued slimming over the next 2–3 months. The effects last about 4 to 6 months, after which maintenance sessions can prolong the results.
