Weak jawline

Lack of mandibular projection can stem from several factors: genetics (family inheritance), aging with loss of bone and soft tissue volume, or retrognathia (naturally recessed position). Posture, progressive skin laxity, and loss of elasticity also play a role. A poorly defined facial oval affects overall facial harmony and can become more pronounced with age.

At Santé, we use high-density hyaluronic acid to restore volume along the mandibular line and create projection. We combine strategic filler techniques with facial mesotherapy and, when indicated, polynucleotides to stimulate collagen production. Our protocol is personalized: we assess bone structure and design a plan that restores natural definition to your facial oval.

Hyaluronic acid results are immediate, though optimal effects appear within 7–10 days once any swelling subsides. We recommend an initial session and, depending on your case, a follow-up at 2–3 weeks. Duration varies by product: 12–18 months typically. Complementary treatments (mesotherapy, polynucleotides) require periodic sessions to maintain collagen.

The procedure is minimally uncomfortable: we use topical anesthesia and a painless technique. There's no significant downtime—only mild redness for a few hours. We recommend avoiding direct pressure on the area for 48 hours and not shaving for 24 hours. There's no age restriction (legal adulthood required) or serious contraindications if you have no known hyaluronic acid allergies.
