Botox (Botulinum Toxin Type A) is a type of protein that directly affects the muscles. When injected into specific areas, it helps temporarily relax the targeted muscles.
For jaw slimming, Botox is injected into the masseter muscles (the chewing muscles) that have become enlarged due to habits like chewing hard foods, clenching the jaw, or grinding teeth while sleeping. As these muscles relax and shrink, the lower face appears slimmer and more contoured.
Jaw Botox is best suited for people whose wide jawline is caused by enlarged jaw muscles.
Typically, 50 units of Botox are used to treat both sides of the jaw in cases where noticeable facial slimming is desired.
Botox takes time to fully activate. You may start to feel a slight tightness or mild soreness during the first week, but visible results usually appear after 3 to 4 weeks. Be patient, the full slimming effect will become clearer in the following month.
The results of jaw Botox typically last around 3 to 4 months, depending on your body and muscle activity. Once the effects wear off naturally, the muscles may gradually return to their original size.The duration varies based on factors such as: Muscle size and strength; Habits like jaw clenching or teeth grinding; How often you receive repeat Botox treatments.
Although some clinics claim the effects last up to 6 months, most people see results that last 3 to 4 months on average. Those who respond well to the treatment or avoid overusing the muscle may enjoy results that last a bit longer.
Jaw Botox targets the masseter muscles directly. It helps reduce the size of the muscles so the face looks slimmer over time.
For best results, doctors often recommend combining both treatments. Together, they help achieve a V-shaped face — a slimmer jaw with more defined contours that many people desire.
Jaw Botox and face lifting Botox reviews:
After getting Botox, no matter the area, proper aftercare is important. It helps the product work more effectively and reduces the chances of side effects. Most side effects are mild and go away on their own.
After jaw Botox, you may notice minor side effects as the product starts to take effect. These can include tightness or soreness in the jaw or feeling like your face is slightly uneven. These are normal and temporary.
This can happen in the first 3 to 7 days, especially in people with strong or bulky jaw muscles. As the Botox starts relaxing the muscle, your body may need time to adjust. Some people feel mild stiffness or limited movement in the jaw, but this will gradually go away on its own.
Right after the injection, the jaw muscles may respond to Botox at slightly different rates. Some areas may relax faster than others, which can create a lumpy or uneven appearance. This is completely normal and usually evens out once the Botox fully settles in around 4 weeks post-treatment.
If you don’t feel any side effects at all, don’t worry — it doesn’t mean the Botox isn’t working. Some people experience no noticeable change right away, but the product is still working in the background. Visible results usually appear in 3 to 4 weeks. It’s a good idea to attend your follow-up appointment so the doctor can evaluate the outcome properly.
Although you may have heard that moving the injected muscle too much is not recommended, light chewing for 5–10 minutes after injection can actually help with absorption in jaw Botox cases. This may help the product start working a bit faster.
You can enjoy grilled or hot foods like BBQ or hot pot. While Botox is sensitive to high heat, only temperatures above 60°C could potentially reduce its effectiveness. Everyday activities like eating hot meals, showering with warm water, or blow-drying your hair are completely safe.
Although jaw Botox is a convenient and relatively safe procedure, one thing you should never overlook is the quality of the product. Using fake or low-quality Botox doesn’t just result in poor or short-lasting effects, it can also cause serious allergic reactions or side effects.
Examples of how to check for authentic Botox:
Before getting Botox, always choose a trusted clinic that uses products directly imported from certified distributors. A good clinic will allow you to inspect the product before injection.
Jaw Botox works best for people whose wide jawline is caused by muscle size, not bone or fat.at. It is also suitable for people who unknowingly overuse their jaw muscles — for example, chewing hard foods often, grinding teeth at night, or clenching the jaw out of habit.
Jaw Botox is only effective if the source of the wide jawline is muscle-related. If the issue comes from fat accumulation or bone structure, Botox alone may not give the results you’re looking for.
To get the best results, it’s always recommended to consult a doctor to accurately determine the cause of your wide jawline and find the most effective treatment for your facial structure.
There are several ways to achieve a slimmer, more contoured face shape. Each method targets a different type of issue
If you're looking for non-surgical options, it’s best to start with jaw Botox or facial lifting treatments that target specific problem areas. Jaw surgery is typically recommended for those with prominent bone structure issues who want long-lasting, dramatic changes.

Jaw Botox injections are not very painful. The needle targets the muscle layer directly and feels like a small pinch or tight sensation. Most people say it hurts less than popping a pimple. At our clinic, we offer cold packs during the procedure, and if you're worried about discomfort, you can request free numbing cream with no extra charge.
Most people get repeat injections every 3 to 4 months, which is when the previous Botox effects begin to wear off. With regular treatments, you'll likely notice that your jaw muscles shrink over time and your face maintains a more contoured shape.
Injecting too frequently, for example, less than 3 months between sessions, may lead to Botox resistance over time. To avoid this, it's best to space out treatments by at least 3 to 4 months, giving your muscles enough time to respond and recover properly. This lowers the risk of reduced effectiveness in the long run.
