The recognition of structural volume loss paved the way for the second evolution: three-dimensional (3D) volumization. Practitioners began restoring lost volume to targeted zones—such as hollowing cheeks or temples. While 3D volumization significantly improved aesthetic outcomes, treating isolated areas in isolation failed to address the root underlying cause of facial aging: gravitational tissue ptosis and structural ligamentous laxity.
To overcome these limitations, Dr. Sarit Cohen developed and presented a pioneering technique at international plastic surgery congresses: Vector-Based Facial Sculpting (4D Rejuvenation).
Rather than simply depositing volume where a hollow appears, this innovative approach applies mathematical vector principles and Newton’s Third Law of Motion (Action and Reaction) to counteract the specific directional forces of tissue descent. By injecting along structural tension vectors rather than flat planes, the sagging tissue is systematically repositioned upward and outward toward its anatomical origins. This integrates time, direction, volume, and structural dynamics into a comprehensive four-dimensional (4D) treatment framework.
The technique centers on reinforcing and lifting the three major retaining ligaments of the face—the true anatomical anchors that secure facial soft tissues to the underlying periosteum:
Lateral Orbital & Temporal Retaining Ligaments: Age-related laxity here causes tail-of-the-brow ptosis, narrowing the eye area and accentuating upper lid heavy fold.
Zygomatic Retaining Ligaments: Weakening allows the cheek fat pad to slide medially and downward, resulting in midface flattening and deepening of the nasolabial folds.
Mandibular Retaining Ligaments: Relaxation along the lower face leads to jowl formation, loss of jawline definition, and the undesirable “bulldog” distortion of the lower third.
By systematically bolstering these anchor points along precise mechanical vectors, the face transitions from an aged, rectangular silhouette back to a youthful inverted triangle or heart shape.
Neocollagenesis & Cumulative Benefits: Vectorial distribution of high-viscosity cross-linked hyaluronic acid stimulates neocollagen formation across broad tissue planes, yielding a cumulative, structural firming effect with repeated treatments.
Micro-Cannula Delivery: Administered via blunt-tip micro-cannulas, minimizing tissue trauma, bruising, and discomfort while maximizing safety around delicate neurovascular bundles.
4D Holistic Coverage: Addresses all three facial tiers—eyebrow/brow tail, midface/cheek, and lower face/jawline—simultaneously.
Ideal Candidates: Excellent for patients who wish to avoid surgery, individuals contraindicated for surgery due to systemic health conditions, patients desiring immediate refinement prior to key events, or those seeking a non-surgical simulation before committing to a surgical facelift.
Note: Vector-Based Facial Sculpting provides dramatic, surgical-like lifting without skin excision. However, for patients presenting with severe skin redundancy and marked tissue overhang, surgical rhytidectomy (facelift) remains the gold standard.
