Dermal Filler Injections

As we age, facial sculpting and wrinkle reduction become increasingly essential components of a modern skincare and aesthetic regimen. Today, both women and men are highly attuned to facial contours and skin quality. Thanks to innovative, high-grade dermal fillers, achieving a refreshed, structurally balanced, and youthful appearance without surgery is a proven reality. Dr. Sarit Cohen, specialist in plastic and aesthetic surgery, offers comprehensive, individually tailored dermal filler treatments performed with clinical precision.

Dermal Fillers for a Natural, Rejuvenated, and Smooth Contour

Key Advantages of Modern Dermal Fillers

Minimally invasive facial contouring procedures have advanced rapidly over the past two decades. This evolution is driven by exceptionally safe filler formulations, sophisticated injection techniques, and short procedure times that allow patients to return immediately to their daily routines. Because distinct facial zones require specific rheological properties (such as elasticity, viscosity, and G-prime stiffness), filler selection is customized during consultation according to skin thickness, tissue layer, and anatomical objectives.

Essential Criteria for Ideal Dermal Fillers:

Biocompatible & Hypoallergenic: Safely integrates into soft tissues with negligible risk of immune reaction.

Stable & Non-Migratory: Remains localized within the targeted anatomical plane without shifting over time.

Predictable & Reversible: Provides reproducible results with the option for complete enzymatic reversal when required.

Natural Aesthetic Integration: Restores volume while preserving dynamic, natural facial movement.

Categories of Dermal Fillers

Temporary Hyaluronic Acid (HA) Fillers

Examples: Restylane®, Perlane®, Stylage®, Juvederm®, Teosyal®.

Properties: Hyaluronic acid is a naturally occurring glycosaminoglycan within the extracellular matrix. Age-related depletion of endogeneous HA leads to structural volume loss, dehydration, and surface creasing. Cross-linked HA fillers restore tissue volume, attract hydration, and offer complete enzymatic reversibility via hyaluronidase.

Semi-Permanent Calcium Hydroxylapatite (CaHA) Fillers

Example: Radiesse®.

Properties: Composed of calcium hydroxylapatite microspheres suspended in an aqueous gel carrier. CaHA consists of minerals naturally present in bones and teeth. Characterized by high viscosity and high elasticity (G-prime), Radiesse® provides immediate structural lift alongside long-term neocollagenesis. It is ideal for defining cheekbones, structural chin augmentation, correcting deep nasolabial folds, post-surgical nasal contouring, and jawline sculpting—making it a preferred filler for male facial rejuvenation.

Clinical Indications: Beautification, Rejuvenation & Asymmetry Correction

Rejuvenation vs. Beautification:

Rejuvenation: Restoring midface volume loss, tear trough depressions, and structural deep folds in patients whose youthful contours have hollowed over time.

Beautification: Sculpting cheekbones, defining the chin projection, or enhancing lip volume in younger patients to optimize facial symmetry and proportion.

Correction of Facial Asymmetry: Suitable for addressing congenital hypoplasia (underdevelopment of one side of the face) or acquired structural imbalances. In cases of facial nerve paralysis, botulinum toxin (Botox) is used in tandem to restore dynamic symmetry.

Key Anatomical Treatment Zones: Tear troughs (nasojugal groove), nasolabial folds, marionette lines, pre-jowl sulcus, cheekbones, chin, jawline, and lip border/volume.

Advanced Technique: Blunt-Tip Micro-Cannulas

A major advancement in facial injections is the transition from sharp needles to blunt-tip micro-cannulas. Through a single tiny entry point, a flexible, rounded cannula navigates safely within subcutaneous planes, dramatically reducing trauma to blood vessels and nerves. This technique minimizes bruising, swelling, and vascular risks while allowing smooth, continuous filler placement across wide anatomical regions.
