Who it suits, who should wait, who is referred on
Tends to suit
- Mild to moderate chin retrusion
- Short lower third of the face
- Deep labiomental fold
- Stable bite and healthy skin
Better to wait
- Pregnancy or breastfeeding
- Active infection or acne near the chin
- Expectation of jaw or bite correction
Referred on
- Marked skeletal discrepancy or bite problem: orthodontic or maxillofacial assessment
- Wish for a fixed implant: referred for surgical assessment
Who should not have this treatment
- Active infection or inflammation near the chin
- Pregnancy and breastfeeding
- Known allergy to hyaluronic acid products or lidocaine
- Long-lasting non-dissolvable filler already present in the area
- Significant skeletal class II or III relationship with malocclusion
- Bleeding disorders or blood-thinning medicines, unless reviewed first
People with a significant skeletal bite discrepancy or fat under the chin tend to respond poorly, because chin filler adds projection to the chin point only.
What happens, step by step
- Consultation and examination: profile and three-quarter photographs, with the chin assessed against the nose and lips
- Written plan and quote: placement, gel choice and any combined treatment are explained, with the fee given in writing
- Treatment day: small amounts placed on bone with the patient upright and checked from both sides
- Review and adjustment: the shape is reviewed once swelling has settled and refinements are discussed
Before you book
- Declare blood-thinning medicines, supplements such as fish oil, and any allergies
- Tell the clinic about pregnancy, breastfeeding or plans to conceive
- Mention recent dental work, jaw problems or any orthodontic treatment
- Avoid sunburn and pause strong skincare actives on the chin if advised
- Bring side-view photographs and records of any previous filler or facial procedures
What determines the fee
The fee for chin filler depends on the amount and type of gel needed, whether the aim is projection, length or fold shaping, and whether jawline filler or masseter botulinum toxin is added to shape the lower face. Gel choice also changes the plan. A written quote is given at consultation after the profile has been assessed, and the consultation decides whether chin filler is advised at all, or whether the nose, neck or jaw is the better target.
How quotes work at this practice: how we quote.
Myths we hear in clinic
“Chin filler can treat a double chin.”Filler adds volume at the chin point and does not remove fat or tighten skin under the chin.
“Chin filler is a substitute for correcting the bite.”It changes soft-tissue and bone-surface contour only; skeletal and bite problems need orthodontic or maxillofacial assessment.
Chin projection options: HA, CaHA, PCL, threads and implants compared
Chin projection can be approached in several ways, and they are not interchangeable. Hyaluronic acid with a high G′ is the usual starting point because it can be dissolved with hyaluronidase. Calcium hydroxylapatite and polycaprolactone are biostimulators with a different mechanism, and neither can be dissolved, so the shape is usually settled first. Absorbable threads are a lifting tool for the jawline, not a way to project the chin point. A surgical implant is a fixed device placed on the bone through an incision, which is why a wish for one is referred for surgical assessment rather than treated with filler. The table sets out how each option works, what it cannot do and where it tends to fit. Which one suits a given chin is decided at assessment, after the profile has been examined.
Chin projection options compared by mechanism, reversibility and limits| Option | How it works | What it cannot do | Reversibility | Where it tends to fit |
|---|
| HA filler (high G′) | Firm cross-linked gel placed on bone at the pogonion or menton | Move the jaw, correct a bite or remove fat under the chin | Dissolvable with hyaluronidase | Mild to moderate retrusion; the usual starting point |
| Calcium hydroxylapatite (CaHA) | Microspheres give support, then act as a scaffold for the patient's own collagen | Be dissolved if the shape is not wanted | Not dissolvable | A chin shape already confirmed, often with HA first |
| Polycaprolactone (PCL) | Collagen-stimulating filler with a different mechanism from HA | Be dissolved, or correct a skeletal or bite problem | Not dissolvable | Patients who know the shape they want |
| Thread lift (Bliss Lift) | Absorbable PDO and PCL cog threads reposition descended tissue along the jawline | Add chin projection or volume | Threads are absorbable and resorb over time | Early jowling where the chin itself is adequate |
| Surgical implant (referred) | Silicone or porous polyethylene implant placed on bone through an incision under anaesthesia | Be adjusted like filler; a fixed shape chosen in advance | Removal or revision means further surgery | A wish for a fixed shape; referred for surgical assessment |
Profile assessment: chin, lips and nose together
In profile, the chin is judged against its two neighbours: the nose above it and the lips beside it. The usual reference is the Ricketts E-line, drawn from the tip of the nose to the soft-tissue pogonion, with the lips read against it. A chin that sits behind the lips can make the nose look more prominent than it is, and a strongly projecting nose can make a normal chin look recessed. The two are linked in the eye, which is why a chin is rarely assessed on its own. At consultation the face is photographed in profile and in three-quarter view, and the chin is read as part of the whole profile rather than as an isolated feature.
The lips are read the same way. Their fullness, their position on the E-line and the depth of the labiomental fold all change how the chin appears. Where the lower lip is thin or sits back, the fold beneath it can deepen and the chin can look less defined than the bone actually is. Norms differ between ethnicities, so the line is a reference point and not a target to be met. Sometimes the finding is that the nose or the lips are doing most of the work, and treating the chin alone would change the wrong thing. That conclusion is as valid as a plan for chin filler, and it is reached at assessment, not assumed beforehand.
Where more than one area is involved, the plan sets out which is addressed first and why. The chin point on bone is often a sensible reference because it changes how the nose and lips read around it, and the other areas are then reviewed against the new line. Nose refinement, lip shaping and chin work use different planes and carry different risks, and the nose is the highest-caution zone for injection, so each is explained separately even when they are planned together. A marked skeletal discrepancy is referred on rather than filled over.
Frequently Asked Questions
How much filler is needed for chin enhancement?
+
The volume of chin filler is set by the anatomy, not by a standard dose. Projection at the pogonion, length at the menton and shaping of the labiomental fold each take a different amount, and a chin that needs all three takes more than one that needs one. It is built up in small boluses to a plan set at assessment.
How long does chin filler last?
+
Chin filler longevity varies between patients and products. Hyaluronic acid is broken down gradually by the body's own hyaluronidase enzymes, at a rate that depends on cross-linking, volume, depth of placement and the individual's metabolism. The chin is a low-movement area supported by bone, which favours persistence. Any repeat is reviewed individually, not scheduled in advance.
Can chin filler be combined with jaw filler?
+
Yes. The chin is the tip of the lower-face outline and the jawline its border; when both are under-defined, filler at the pogonion and menton is planned with filler along the mandibular border and angle so that they read as one line from ear to chin. Each area is assessed separately and the sequence decided at consultation.
Is there downtime after chin filler?
+
Recovery after chin filler varies. Swelling, tenderness, tightness and some bruising at the entry points are normal, and the chin can look slightly uneven while swelling settles. Increasing pain, skin that turns pale, dusky or mottled, or persistent altered sensation of the lower lip are not normal recovery and warrant same-day review.
What is the price of chin fillers in Singapore?
+
The cost of chin filler depends on what the assessment finds: whether projection, length or soft-tissue shaping is required and how much of each, the filler chosen, whether the chin is treated alone or with jawline filler or masseter BTX, and how the plan is staged. A personalised plan with its cost is set out at consultation.
Can chin fillers create a V-shape face effect?
+
Chin filler addresses one part of a V-shape: the defined tip. The narrow angle comes from the jaw, and where the width there is muscular, masseter BTX acts on it, a different mechanism on a different structure. Where the width is bony, neither narrows it. The combination is decided by examining both the chin and the masseter.
Does chin filler treat a double chin?
+
No. A double chin is fullness under the jaw, whether submental fat, lax skin or platysma laxity, and chin filler does not remove any of it. Filler changes where the bony chin sits in profile; a more projected chin point changes how the chin-neck angle reads, but the submental area itself is assessed and treated separately.
How much does chin filler cost in Singapore?
+
The fee depends on how much gel is needed, whether the aim is projection, length or fold shaping, the product chosen, and whether jawline filler or masseter botulinum toxin is added. Dr Sin Yong gives a written quote at consultation after assessing the profile, and the consultation also decides whether chin filler is advised at all.
Is chin filler worth it?
+
It tends to suit someone with mild to moderate chin retrusion, a short lower third or a deep labiomental fold who has a stable bite. It is the wrong tool for a marked skeletal discrepancy, bite problems, or fullness under the chin that is fat rather than a weak chin. Assessment of the profile decides.
What are the disadvantages of chin filler?
+
It does not move the jaw, correct a bite or remove fat under the chin. Swelling, bruising, lumps, asymmetry and gel movement can occur, and it is temporary by design. The serious disadvantage is the uncommon risk of blocked blood flow, which is why anatomy and technique matter.
