Chin filler adjusts the projection, height and shape of the chin. It is a procedure with a big impact on the facial profile and on the proportion of the lower third, often underestimated by the patient, who arrives asking about the nose or lips and discovers in the assessment that a poorly projected chin was part of the concern.

On this page you will find the indication, usual volumes, durability, risks and how to simulate it in Harmy.

What is chin filler?

It is the placement of supportive hyaluronic acid, or another structural filler, in the chin to increase forward projection, adjust vertical height or correct asymmetries. The goal is to balance the chin with the nose, the lips and the jawline.

The chin is one of the pillars of the lower third. Small changes in projection can alter how the whole profile reads, toward more or less harmony, and that calls for careful planning.

Who is chin filler usually indicated for?

Generally, for patients with:

  • a poorly projected chin (mild to moderate retrogenia) in profile view;
  • a lower third that is short relative to the other thirds;
  • mild chin asymmetry;
  • loss of definition in the transition between chin and jaw.

Significant retrusion, or bite or bone growth problems, usually call for an orthodontic or surgical assessment before any filler. General contraindications include active infection, active autoimmune disease, pregnancy, breastfeeding and allergy to the product. The decision belongs to the qualified professional, in line with the rules of their professional council in Brazil.

Which areas are involved?

The main area is the chin. It continues into the jawline, and the plan for the two is usually made together, because a projected chin with an undefined jaw can look isolated. The lips also enter the analysis, because of the profile relationship between them and the chin.

Which product is used?

Generally, high-G' hyaluronic acid, with good projection capacity and resistance to deformation. Some professionals use calcium hydroxyapatite in the area. The reversibility of hyaluronic acid is an advantage when adjusting the profile. Product, instrument and plan are technical decisions for the professional.

What volumes are usual?

The ranges below are general references; the final volume is set by the qualified professional after assessment.

Goal Usual total range Note
Discreet adjustment of projection or asymmetry 0.5 to 1 ml Common in a first treatment
Moderate projection 1 to 2 ml Frequent range in practice
Projection and lengthening 2 to 3 ml or more Consider stages

The chin is a midline area, so the volume is not split between two sides as in bilateral areas.

How long does chin filler last?

With supportive hyaluronic acid, usual durability is generally between 12 and 18 months. The area has moderate movement, influenced by the mentalis muscle. Product, volume and the patient's metabolism also matter.

What are the risks and complications?

The most frequent complications are swelling, bruising, local pain, asymmetry, nodules and, with high volumes, an elongated or heavy-looking chin. The action of the mentalis muscle on the product can, in some cases, favor irregularities.

The area is supplied by branches of the mental artery, the inferior labial artery and the submental artery. An intravascular injection can cause vascular occlusion, with a risk of skin injury. Hyaluronidase must be available whenever hyaluronic acid is used, with a known management protocol. See also safety and complications in facial harmonization.

What care is needed before and after?

Beforehand, the medical history should record anticoagulants, previous procedures in the area (including implants and permanent products), ongoing orthodontic treatment and autoimmune disease. Front and profile photos help a lot in the assessment, even though the simulation in Harmy uses only the frontal one.

Afterward, usual instructions include avoiding pressure and massage in the area, intense heat and heavy exercise for 24 to 48 hours. Disproportionate pain, pallor or purplish patches call for immediate contact with the professional. A follow-up at about 15 to 30 days allows projection and symmetry to be assessed.

How do you assess whether the chin is the real concern?

The patient almost never arrives asking about the chin. A few observations help show them the relationship between the chin and the rest of the face:

  • Profile: compare the projection of the chin with that of the lips and the tip of the nose. A retruded chin makes the nose look larger and the lips more projected.
  • Thirds: a lower third that is short relative to the middle and upper may call for height, not just projection.
  • Contraction: if the chin dimples when the mouth closes, the mentalis muscle is overworking, and toxin may enter the plan.
  • Bite: retrusion with an occlusal problem calls for assessment by another specialty first.

For an overview, see facial assessment by thirds.

What is not promised to the patient

  • An effect equivalent to genioplasty or orthognathic surgery.
  • Correction of the bite or of functional problems.
  • An "ideal" profile or one identical to a reference.
  • Absolute symmetry.
  • An exact duration.

Simulation in Harmy

The image at the top of this page was generated by Harmy itself, using the fictional person we use across all our pages, marking only the Chin point with 1 ml. Drag the line to compare. The change is subtle on purpose: the AI alters only the marked area, respecting the volume, and does not retouch the skin or change expression, lighting or background. It is an honest projection. It is an illustrative simulation, not a promise of results.

In the app, chin filler and botulinum toxin in the mentalis share the same point, Chin. The simulation shows the effect of the point as a whole. Because the photo is frontal, the change in projection shows less than it would in profile: it is worth telling the patient and complementing the conversation with the profile photo from the assessment.

How to simulate in 3 steps

  1. In New projection, enter the patient's name and use a frontal photo with the face straight and the mouth relaxed.
  2. In the marking screen, tap the Chin point and set the volume in the Plan (from 0.5 to 5 ml, in 0.5 steps).
  3. Tap Create projection and compare on the Before / After slider.

Details and screenshots in how to mark areas and volumes. If the plan includes the jaw, mark the Jawline point as well to show the lower third as a whole.

Frequently asked questions

How long does chin filler last?

Generally 12 to 18 months with supportive hyaluronic acid, depending on the product, the volume and the patient's metabolism.

How many ml are used in chin filler?

Generally 1 to 3 ml in total, and possibly more in stages, at the discretion of the qualified professional after assessment.

Does chin filler replace genioplasty?

Not in every case. In mild to moderate chin retrusion, filler can improve projection. In significant retrusion or with a bite problem, surgical assessment is usually more appropriate.

Does chin filler improve the profile?

It can improve profile balance when the chin is poorly projected relative to the nose and lips. The effect depends on each patient's anatomy.
