Jawline Fillers at RE:BERRY Gangnam Seoul — Sculpted Definition Without Surgery

Mandibular Anatomy and Aesthetic Jawline Proportions

The aesthetic jawline comprises three anatomical zones that jawline fillers target: the mandibular angle (gonion), the mandibular body, and the mental region (chin). An ideal jawline demonstrates a clear mandibular border from the ear to the chin with defined angularity at the gonion. Age-related changes — including bone resorption, fat pad descent, and skin laxity — progressively blur the jawline definition. Research by Mendelson and Wong (2012) demonstrated that mandibular bone remodeling with aging reduces the gonial angle projection by 5-8 degrees per decade after age 40, contributing to jowl formation and loss of jaw definition. Jawline fillers restore this lost structural support by providing volume at the supraperiosteal level.

Hyaluronic Acid Fillers for Structural Jawline Definition

High G-prime (high-firmness) hyaluronic acid fillers are the standard for jawline augmentation because they resist compressive forces and maintain projection under the mechanical stress of jaw movement. Raspaldo et al. (2017) published a multicenter study evaluating HA filler for jawline contouring in 120 patients, demonstrating statistically significant improvement in jawline definition on the Merz Aesthetic Jawline Scale at 6 and 12 months post-injection. The study reported 92.5% patient satisfaction, with the high-cohesivity HA filler maintaining its structural integrity along the mandibular border for a mean duration of 14.2 months. At RE:BERRY Gangnam, Juvederm Volux is the primary HA filler for jawline definition due to its Vycross cross-linking technology that provides superior lift capacity.

Calcium Hydroxylapatite for Biostimulatory Jawline Enhancement

Radiesse (calcium hydroxylapatite) provides a unique dual mechanism for jawline fillers: immediate volumetric support from the CaHA microspheres suspended in carboxymethylcellulose gel, followed by long-term neocollagenesis as the microspheres stimulate type I and type III collagen production. Loghem et al. (2015) demonstrated through histological analysis that CaHA microspheres create a scaffold for fibroblast infiltration, generating organized collagen bundles that persist well beyond the carrier gel’s absorption. This makes Radiesse particularly effective for jawline fillers in patients with moderate skin laxity, as the collagen stimulation provides a secondary tightening effect that complements the structural volumization.

Safety and Vascular Anatomy in Jawline Injection

Safe jawline filler injection requires thorough knowledge of the facial artery and vein course along the mandibular border. The facial artery crosses the mandible at the anterior border of the masseter, making the posterior jaw (angle) a relatively safer zone for deep bolus injections. DeLorenzi (2014) published comprehensive vascular mapping guidelines demonstrating that supraperiosteal injection along the posterior mandibular body carries minimal vascular risk when performed with aspiration and slow injection technique. At RE:BERRY Gangnam, Dr. Ryu employs blunt-tip cannulas along the mandibular body to further reduce vascular injury risk, reserving sharp needle technique for deep periosteal injections at the mandibular angle where the tissue is thicker and vessels are more superficial and identifiable.
