Chin Filler Effects and Before/After Precautions: Improving Protruding Mouth and Short Jawline
For those concerned about a protruding mouth caused by a weak or short chin, we have summarized the effects and procedure of Chin Filler. Check out real cases from 345 Skin Clinic to see how to naturally correct your chin line and find your face's golden ratio.

The Impact of a Weak and Short Chin on Your Overall Impression
A weak chin, characterized by a short or receding jawline, is not just a problem of the lower face. When the tip of the chin is pushed back, it not only makes the mouth look relatively more protruding, but it also blurs the boundary between the neck and the face. This can result in a heavy-looking impression or an uneven side profile.
A representative procedure that can compensate for these facial balance concerns without surgery is Chin Filler. By naturally filling in the volume at the tip of the chin, it improves the overall proportions of the face and creates a sophisticated image.

Features and Real Cases of 345 Skin Clinic's Chin Filler
345's chin filler does not simply focus on filling the empty space at the tip of the chin. We aim for a natural change in impression by considering each patient's three-dimensional facial proportions and muscle movements.

The case above is a male patient who visited us with concerns about an angular and receding weak chin. Looking at the changes after the procedure, you can see that the chin line has been repositioned downward and forward, improving into a neat and three-dimensional contour. The protruding mouth impression, which was emphasized by the short chin, has been naturally refined, bringing harmony to the overall balance of the face.

We Recommend Chin Filler to the Following People
- Those whose mouth appears protruding due to a short or receding chin
- Those with an uneven side profile and a sharply angled chin tip
- Those who prefer a procedure with a faster recovery than surgical methods
- Those who want to find their face's golden ratio and create a three-dimensional impression

Sophisticated Design Procedure: Why Choose 345?
In filler procedures, 'how it is designed' makes a bigger difference in the outcome than the amount injected. Our clinic adheres to the following principles to provide highly satisfying results.
- Precise Analysis: We analyze the face shape, contour lines, and the length and angle of the chin from multiple perspectives.
- Design Molding: Rather than simply injecting volume, we go through a sophisticated molding process tailored to facial harmony.
- Genuine Product & Exact Dosage Principle: We only use fillers with proven safety and adhere to a one-filler-per-person rule.
- Mark-Vu System: We establish a treatment plan optimized for individual skin conditions using advanced skin diagnostic equipment.


Post-Procedure Care and Recovery Guide
With chin filler, you can see gradual changes immediately after the procedure, and recovery is fast enough to return to daily life right away without needing time off. However, since the filler settles for about 1 to 2 weeks after the procedure, you should observe the following precautions.
- Do not apply strong pressure to or touch the treated area.
- It is best to avoid high-temperature places such as saunas and jjimjilbangs (Korean bathhouses) for a while.
- Please refrain from drinking and smoking to lower the risk of inflammation.
- Mild swelling or bruising will naturally disappear within a few days.

When the jawline is refined, it creates a visual effect that makes the facial features look much more defined. If you want to improve a heavy-looking impression caused by a weak chin, we invite you to experience your own golden ratio through 345's Chin Filler, which provides precise diagnosis and detailed design.
