In modern facial contour aesthetics, jaw filling is one of the most common and effective non-surgical methods. A three-dimensional, full chin can not only modify the proportion of face shape, but also make facial features more harmonious, more three-dimensional sense. Whether it's creating a v-shaped face, improving a short chin, or correcting facial asymmetry, filling the chin can provide a significant visual boost.
However, any injection of medical beauty projects are not zero risk. Even with a well-established technique, there is a chance of Side Effects.
Understanding these potential risks, their causes, and how to prevent them can help us be safer and more rational in our pursuit of beauty.
This article will give you a comprehensive understanding of the common side effects of Chin Filler, scientific prevention and postoperative care focus, so that your road to beauty more peace of mind.
What is Chin Filler?
Chin Filler is a cosmetic treatment that uses implants to improve the appearance of the Chin. Fillers such as Hyaluronic Acid, PLLA or hydroxylapatite calcium (Caha) are injected into the jaw area to increase volume and lengthen the jaw line to optimise facial proportions.
The main benefits include:
Improve the short chin, back chin;
Modify the face shape to make the contour more smooth;
Correction of facial asymmetry;
Enhance the clarity of the jaw line, so that more three-dimensional features.
Common materials of Chin Filler
Knowing the filling material can help you understand possible sources of side effects:
Hyaluronic Acid (HA)
The most common chin filler.
Advantages: High Safety, can be absorbed by human body, can be reversed by lysozyme.
Side effects are usually mild, such as swelling and bruising.
Poly (l-lactic acid)(Plla)
Shaping is achieved step by step by stimulating collagen regeneration.
Advantages: long-lasting natural effect;
Risk: if the injection level is incorrect or the massage is insufficient, nodules may occur.
Calcium hydroxylapatite (Caha)
Both immediate support and long-term stimulation of collagen;
Hard texture, suitable for men or the need for a clear contour;
Risk: if the injection layer is too shallow, a lump or unevenness may form.
Note: The nature of the material determines the risk of complications, so the face shape, skin thickness, and desired outcome should be evaluated by a medical professional prior to injection.
Common side effects of Chin Filler
1. Swelling & Bruising
This is one of the most common side effects, and almost everyone who gets a chin filler experiences mild redness and swelling.
Cause: needle capillary, exudation of tissue fluid, or mild inflammation of the body.
Performance: after the injection chin slightly swollen, fever or slightly blue, generally 3-7 days can be self-resolving.
Relief: ice for 10-15 minutes within 24 hours after surgery; avoid massage, heat and strenuous exercise.
Professional advice: if the swelling continues for more than a week or accompanied by pain, should be promptly revisited to rule out infection or inflammatory reaction.
2. Pain or Tenderness
Pain, tenderness or tightness at the injection site for a short period of time is a normal reaction.
Causes: needle stimulation of nerve endings, increased tissue tension, or local swelling and compression.
Ease the way: generally 2-3 days after the self-regression, doctors can take the recommended pain medication.
3. Lumps or Nodules
Local unevenness, hard lumps or nodules are common complications during filling.
Reasons: The filler is unevenly distributed, the injection level is too shallow, gentle massage is not followed after the operation, or the fibrous tissue in the body reacts excessively.
Symptoms: There are small particles or hard lumps on the chin when touched, and some may be slightly painful.
Processing method:
Mild cases can be absorbed on their own;
Obvious nodules can be gently massaged under the guidance of a doctor;
If it is caused by hyaluronic acid, hyaluronidase can be used to dissolve it.
4. Asymmetry/Uneven Shape
After filling, some people will find that there is asymmetry between the left and right or that the chin is too pointed or too long, making it look unnatural.
Reasons: Uneven injection volume control, asymmetry of the original bone foundation or postoperative swelling lead to visual differences.
Solution:
Evaluate 7–14 days after surgery after swelling has subsided;
The doctor will make fine adjustments or additional injections if necessary.
5. Filler Migration
The shape of the chin changes after filling and the lines are not smooth, which may be caused by the displacement of the filler.
Reasons: too shallow injection level, too much injection volume, frequent exercise or massage after surgery, and loose skin.
It manifests as jaw contour deformation, asymmetry, or a strange feeling when touched.
How to deal with it:
For hyaluronic acid filling, it can be reversed by dissolving enzymes;
Other types need to wait for metabolic absorption or doctor adjustment.
Prevention methods: Avoid lowering your head, clenching your teeth, and pressing your face while sleeping after surgery.
6. Infection
Although the incidence is low, infection is one of the most important risks.
Reasons: Dirty operating environment, improper postoperative care, or the patient touching the injection area.
Manifestations: persistent redness, swelling, fever, pain, exudation and even the formation of pustules.
Countermeasures:
Seek medical attention as soon as possible and treat with antibiotics;
In severe cases, the source of infection needs to be eliminated and treated symptomatically.
7. Vascular Occlusion
This is the most serious, but rare, side effect of chin augmentation. Mainly because the filler accidentally enters the blood vessels or compresses the blood flow, causing tissue ischemia and necrosis.
Manifestations: Severe pain at the injection site, white or black skin, and cold touch; in severe cases, it can cause skin necrosis or scarring.
First aid measures:
Stop the injection immediately;
Immediately inject hyaluronidase to break down the filler;
Hot compress, vasodilator treatment, and local massage promote blood flow;
Use anticoagulants and oxygen therapy if necessary.
Key to prevention: Choose a doctor who is familiar with facial vascular anatomy, use a blunt needle to inject and inject slowly.
8. Nerve Injury
Although rare, if the operation is too deep or the position is wrong, the nerve may be accidentally injured.
Symptoms: Numbness, tingling, or lack of movement in the lower lip or chin area.
Most are temporary compressions that can heal on their own within a few weeks; very few require medical intervention.
Prevention method: Doctors should avoid operating close to the mental nerve exit point, and the injection speed should be slow.
4. Why do these side effects occur?
The occurrence of side effects is usually caused by the following reasons:
Technical problem for doctors: The blood vessels and nerves in the chin area are complex. If the injection level or angle is wrong, it can easily lead to displacement, blood vessel compression or nodules.
Poor product quality: Inferior fillers have many impurities and low purity, which may cause inflammatory reactions.
Individual differences: Different people have different skin thickness, metabolic rate, and immune response.
Improper post-operative care: early compression, exercise, heat or exposure to the sun will affect filling stability.
5. How to prevent the side effects of Chin Filler?
Choose qualified doctors and institutions
Professional doctors are familiar with the anatomy of the jaw blood vessels and can correctly control the depth and dose to reduce the risk of complications.
Use certified products
Give priority to brands certified by FDA, CE or ISO, such as Juvederm, Restylane, Diaminy Filler, etc.
Adequate communication before surgery
Inform the doctor of past medical history, drug allergies, and filling experience. Avoid injecting during your menstrual period or while taking anticoagulant medications.
Accurate injection level
Chin fillers should be placed in the supraperiosteal or subdermal layer to avoid superficial injections.
Postoperative precautions
Avoid touching, wearing makeup, and intense facial expressions within 24 hours;
Avoid hot compresses, saunas, and alcohol consumption within a week;
Moisturize more to keep your skin soft and elastic.
6. Treatment methods after side effects occur
If the following situations occur, you must return to the hospital for follow-up treatment immediately:
Severe pain, skin turns white or purple;
Local redness and swelling persist for more than 3 days;
Hard lumps, exudates or asymmetric deformation appear.
Doctors can use hyaluronidase dissolution, anti-inflammatory, hot compress, laser-assisted treatment and other treatments according to the specific situation. Do not massage or apply ointments on your own to avoid aggravating inflammation.
7, How to judge whether you are suitable for chin filling?
Situations that may suit you for chin fillers include:
The chin is short, retruded, or poorly defined;
- Unbalanced facial proportions and lack of three-dimensionality;
- Want to improve side facial lines or V-face effect;
- I don’t want to undergo surgery and want to recover quickly.
- You should be cautious or avoid if you have:
- Skin infection and wounds that have not healed;
- Have a history of severe allergies or immune diseases;
- Pregnancy, lactation;
- A permanent prosthesis was implanted in the chin area.
