However, to understand the effects and the manifestations after jawline Botox injections, we need to carefully research this topic as well as the important things to keep in mind in the following article.
1. What is jawline Botox injection?
Jawline Botox injection is a modern beauty method in which Botulinum Toxin is injected into the muscle to create a relaxing effect. This Botox substance is a refined protein, mainly Botulinum Toxin Type A, produced in the USA.
When injected into the muscle, this active ingredient blocks signals from the nerves to the muscles, helping them relax and reducing their ability to function. As a result, dynamic wrinkles caused by muscle contractions will be minimized, and the masseter muscle will also reduce hypertrophy, helping the face become slimmer and achieve a more V-line shape. This method not only provides natural beauty but also helps improve the user's confidence.

2. Is jawline Botox injection dangerous?
Jawline Botox injection can be safe if performed correctly by a qualified physician. This is a method that has been used for over 50 years in medicine and aesthetics, with many applications such as treating strabismus, eyelid spasms, and reducing wrinkles.
However, some misconceptions suggest that Botox will completely paralyze the facial muscles. In reality, when injected with the correct dosage, Botox only helps relax the muscles without completely stopping them from functioning. If overdosed or injected incorrectly, side effects could occur, such as:
Jaw sagging: Due to over-affected masseter muscles.
Masseter hypertrophy: When injected improperly.
Dry mouth: An unwanted reaction that may occur.
Distorted smile: Clients may have difficulty smiling naturally.
To ensure safety and effectiveness, clients should choose reputable facilities with a brand name and a team of highly skilled doctors. This not only helps minimize risks but also ensures the best aesthetic results.
3. Common symptoms after jawline Botox injection
Below are some common symptoms after jawline Botox injection, helping you understand more about the changes that may occur on your face after this cosmetic procedure.
Swelling, bruising
After each injection, bruising and swelling at the injection site is common. These bruises typically disappear on their own after 5-7 days. To minimize the possibility of bruising, you should avoid blood-thinning substances such as ginseng, garlic, fish oil, and medications containing aspirin or heparin before the injection.

Prolonged hematoma
Hematomas can occur when the needle touches arteries that supply blood to the masseter muscle, such as facial and mandibular arteries. This condition can cause pain and facial swelling, affecting health and daily activities.
Dizziness and headaches
Dizziness and headaches are also one of the common symptoms after jawline Botox injection. Although not very common, some clients may experience headaches and dizziness. In one study, headaches were reported in 2 clients and dizziness in 1 client out of a group of 220 patients. Those with headaches may face this issue in subsequent treatments.
Asymmetry
The condition of asymmetry between the two sides of the face can occur if the doctor does not recognize the difference between the left and right masseter muscles, often due to uneven chewing habits prior to treatment.
Sagging condition
In middle-aged clients and older, Botox injections can worsen sagging in the jaw area. The reason is that the skin does not tighten and firm up at the same pace as the masseter muscle. Experienced doctors usually adjust the dosage and treatment timing to limit this phenomenon.
Masseter muscle reverting
The next common symptom after jawline Botox injection is the reverting of the masseter muscles. This condition can occur within a week after injection, due to the hypertrophy of the superficial masseter muscle fibers. They usually resolve on their own after a week without intervention. If it persists or worsens after 1-2 weeks, doctors may inject an additional 5-10 units of Botox into the superficial layer to adjust.

4. Who should have jawline Botox injections?
Below are appropriate candidates for jawline Botox injections:
Only individuals aged 18 and older are eligible for Botox injections.
Those with thick masseter muscles on both sides, causing a square jawline and lacking slimness.
Those with uneven jaw angles, large or coarse jaws.
Individuals who wish to have a V-line face but are hesitant about surgery and concerned about scarring or pain.
5. Post-jawline Botox injection care to avoid complications
Below are care methods that should be followed after jawline Botox injections to ensure safety and effectiveness:
5.1. Avoid hard, chewy foods
After Botox injections, you should limit eating hard and chewy foods to avoid damaging the jaw muscles. Prioritize soft, easy-to-chew foods to reduce pressure on the masseter during the recovery phase. After botox injections, you should limit eating hard and chewy foods to avoid damaging the jaw muscles. Prioritize soft, easy-to-chew foods to reduce pressure on the masseter during the recovery phase.
5.2. Do not manipulate the injection area
In the first few hours after injection, you need to minimize activities that may affect the jaw area, such as massaging or touching. This is the time when Botox takes effect and the jaw muscles are not stable, so manipulation may lead to jaw misalignment and unwanted complications.
5.3. Avoid facial treatment methods
Massage or facial treatment techniques can affect the facial muscles. Additionally, some cosmetic products may react with Botox. Therefore, you should limit the use of cosmetics, exfoliants, and facial skin care in the days following the treatment.

5.4. Do not apply pressure on the face
Avoid daily habits that may put pressure on the face, such as bending your head, resting your chin, wearing a too tight helmet, or lying on one side. Just avoid these habits for the first few days until the facial muscles stabilize more.
5.5. Do not use stimulants
Alcohol, beer, coffee, and carbonated drinks can affect the nervous system and react with Botox, causing unwanted side effects. For safety, you should avoid these types of drinks for two weeks after injection. Instead, drink plenty of water and use smoothies, fresh fruit juices to boost your immunity and promote recovery.
5.6. Chew evenly on both sides
To ensure balance for the jaw muscles, you should try to chew evenly on both sides. This helps avoid asymmetry between the masseter muscles, reducing the risk of complications.
5.7. Follow-up appointment
Don’t forget the follow-up schedule as directed by your doctor. Regular check-ups help monitor the condition and effectiveness of the treatment process, while also promptly detecting and addressing any issues if they arise.
