Understanding face slimming botox
What is botox?
Botox is a neurotoxin protein produced by Clostridium botulinum during its reproduction. It was originally used to treat facial muscle spasms and other muscle movement disorders. It was used to paralyze muscle nerves to stop muscle spasms.
It was later used in the aesthetic field. Botulinum toxin can block the nerve impulses between nerves and muscles and relax the overly contracted small muscles, thereby achieving the wrinkle removal effect of Botox.
It can temporarily paralyze muscles, causing the muscles to atrophy due to loss of function, to achieve the purpose of sculpting lines, which is commonly known as wrinkle removal and face slimming, slimming legs, slimming shoulders, etc.
Face slimming botox introduction
For people with wide and asymmetrical faces due to masseter muscle hypertrophy, face slimming injections are a quick and effective method.
The masseter muscle is usually part of the masticatory muscle group. It is located under the cheekbone. It looks like a garlic clove when viewed from the side. When you are chewing something, press your hand on your cheek and you will feel a tight and hard muscle.
The masseter muscles on the face become developed due to long-term chewing. Some people’s masseter muscles are more obvious, making their faces appear square and big. Some people chewing on one side for a long time can also cause facial asymmetry.
How does face slimming botox work?
The face slimming botox is injected into the masseter muscle. The principle is to use botulinum toxin to block the nerve impulses between nerves and muscles after being injected into the muscle layer, allowing the over-contracted facial masseter muscles to relax and paralyze over-developed muscles to achieve the effect of slimming the face.Â
Through the effect of Botulinum toxin, the muscle fibers of the masseter muscle become thinner and the muscles become “lazy”, allowing the masseter muscle to relax and no longer be tight.
The same principle applies to thinning shoulders and thinning calves. For example, well-developed muscles are like a clenched fist. The muscles are in a tight state due to long-term exercise. After botox injection, the muscles begin to slowly relax and no longer shrink into a ball, overall, the face is smaller than before, achieving a face-slimming effect.
Generally speaking, face-slimming injections are suitable for people with good facial structure and masseter muscles, but not much flesh. After the injection, the mandibular line and chin shape will be much clearer, adding a sense of refinement.

How many units of Botox needed for face slimming?
For face slimming, 25-50U of botulinum toxin is generally injected on each side, 2-4 points to inject. The procedure can be completed in about 15-20 minutes.
Precautions after face slimming injection
- There may be weakness in chewing and soreness in the early stage after injection, which is normal and will disappear after a few days;
- Within 6 hours after injection, avoid washing your face and touching the injection site;
- No need to apply cold compress or hot compress;
- Avoid strenuous exercise within 24 hours after injection;
- Avoid massaging or rubbing the injection site within 1-2 weeks after injection to prevent the drug from spreading to other parts;
- Avoid spicy, seafood, and alcohol within a week, and avoid chewing hard food and chewing gum in the future;
- Go to the hospital for regular follow-up visits as directed by your doctor.
How long does it take to see results from face slimming botox?
Botulinum toxin injection does not act as a filler, so it will not be effective immediately. The absorption of the botox requires a process.
Face slimming botox will start to take effect in about 2 weeks after injection, and the muscle tissue will slowly begin to slow down its movement. Generally, the effect will be most obvious in 1-2 months.
For customers who are injected for the first time, the body will absorb faster and need to inject a larger dose of the botox. It is generally recommended to supplement the injection after 4-6 months. This can double the effect.
