How much filler is needed for jawline definition?

Jawline filler typically requires 1 to 3 syringes (1–3 ml) depending on the starting anatomy, the degree of definition desired, and whether the chin is treated simultaneously. The doctor assesses the precise amount needed at your free consultation, considering facial proportions and balance.

How long does jawline filler last?

Jawline filler lasts between 12 to 18 months. The jawline is a low-movement area, so hyaluronic acid is metabolised more slowly than in high-movement zones like the lips. Results depend on the specific product used, metabolism and lifestyle.

Can jawline filler slim the face?

Jawline filler defines and sharpens the lower face, which can create a slimming and contouring effect. It does not reduce fat but improves the visual definition of the jaw angle and chin projection. In some cases, it is combined with Botulinum toxin to the masseter muscles for a more comprehensive lower face reshaping effect.

What is jawline filler

Jawline filler defines and sculpts the mandibular line using high-cohesivity hyaluronic acid. It reshapes the mandibular angle, counteracts the age-related descent of the facial contour, and creates a clean transition between face and neck. One of the most requested facial harmonisation treatments in Lisbon, it appeals equally to men and women seeking a more structured profile without surgery.

Who is it for

Adults with a poorly defined mandibular line, age-related facial descent, mild jaw asymmetries, or those after a sculpted jawline without surgery. Particularly effective for correcting jowling, the sagging of the lower cheeks over the jaw. In cases of significant skin laxity, we often combine jawline filler with biostimulators for a complete result.

What to expect from the session

Sessions last 45 to 60 minutes. After topical anaesthesia, high-cohesivity hyaluronic acid is placed in a deep plane on the mandibular periosteum at strategic points, angle, body, and junction with the chin, on both sides. Technique combines bolus and linear deposits, with symmetry and natural contour as the guiding principles.

Results timeline

The jawline becomes more defined immediately, with a visible result right after the session. Final results settle after 14 days. Because of the deep periosteal placement and the low mobility of the area, longevity is impressive: 18 to 24 months, with annual maintenance recommended.

Aftercare

Avoid make-up for the first 12 hours and hold off on saunas, the gym, alcohol, and sun exposure for 48 hours. Sleep on your back for the first two to three nights. Small bruises are possible and typically resolve in 5 to 7 days. Topical arnica aids recovery, and SPF 50 should be worn for two weeks.
