Rejeunesse Shape Lidocaine Filler

Description

Rejeunesse Shape with Lidocaine is the most robust, high-viscosity injectable dermal filler within the advanced product line developed by Newmedic Co., Ltd. (South Korea). Specially formulated as a highly dense, monophasic cross-linked Hyaluronic Acid (HA) gel, this formulation is engineered for deep structural remodeling, non-surgical facial bone sculpting, and the correction of severe dermal folds. Utilizing proprietary UPHEC Technology (Unique Purification High-Concentration Essential Cross-linking), the gel undergoes an intensive multi-stage purification protocol that maximizes cross-linking efficiency while thoroughly removing unlinked BDDE residues and bacterial endotoxins. Rejeunesse Shape exhibits an exceptional elastic modulus (G-Prime), providing maximum mechanical lifting power, outstanding resistance against deformation, and precise structural projection. Infused with 0.3% Lidocaine Hydrochloride to maintain complete patient comfort, it safely integrates within deep subcutaneous or supra-periosteal tissue planes to restore sharp facial definition and volume.

Main Benefits of Rejeunesse Shape with Lidocaine

• Maximum Structural Lifting & Projection: Engineered with a dense, highly cohesive monophasic structure that provides superior mechanical lifting power to sculpt bone contours and fill severe tissue depressions.

• UPHEC Triple-Purification Safety: Advanced processing ensures an exceptionally pure gel with undetectable chemical residues, minimizing the risk of post-injection swelling, delayed-onset granulomas, or hypersensitivity.

• Highly Stable Shape Retention: The tightly woven monophasic gel mass resists migration and holds its structural shape beautifully, making it ideal for sharp, defined facial contouring.

• Integrated Local Anesthetic: Formulated with 0.3% Lidocaine Hydrochloride to effectively numb deep tissue layers, delivering a painless and highly comfortable treatment experience during deep structural delivery.

• Extended Enzymatic Resistance: The ultra-concentrated, cross-linked HA matrix highly resists natural breakdown by hyaluronidase enzymes, providing stable, long-lasting aesthetic volume for 12 to 18 months.

Indications

Rejeunesse Shape is specifically indicated for deep subcutaneous or supra-periosteal (on bone) injections to reshape facial bone structure, restore deep fat pads, and smooth out severe folds:

• Chin Augmentation & Projection: Correcting weak, recessed chins and lengthening the chin profile for an improved facial balance.

• Jawline Contouring & Definition: Creating a sharp, sculpted mandibular angle and defining a continuous jawline perimeter.

• Cheekbone & Malar Volumization: Rebuilding depleted submalar fat structures and augmenting flat, hollow cheekbones.

• Nose Reshaping (Non-Surgical Rhinoplasty): Straightening nasal dorsal humps, defining the nasal bridge, and projecting the nasal tip.

• Severe Nasolabial Folds: Filling deep, heavy facial expression creases that run from the nose down to the corners of the mouth.

Mechanism of Action

Rejeunesse Shape restores high-definition volume through a cohesive Hydrophilic Structural Volumization pathway:

1. Immediate Mechanical Cushioning: Upon deep delivery, the dense monophasic HA gel acts as a solid mechanical cushion. It lifts the overlying skin layers, fills deep tissue voids, and mimics bone structure to create sharp facial definition.

2. Hydrophilic Water Retention: The non-animal HA molecules absorb surrounding water molecules up to 1,000 times their own weight, expanding slightly into tissue gaps to provide long-lasting internal hydration and volume stability.

3. Resilient Cross-Linked Matrix Retention: Thanks to UPHEC processing, the tightly bound HA chains resist rapid breakdown by endogenous hyaluronidase enzymes. The gel degrades evenly over months, maintaining a stable lifting effect throughout its lifecycle.

Administration Protocol

• Delivery Formats: Administered exclusively by licensed medical professionals using precise injection techniques. This product is typically delivered via bolus technique directly onto the bone for chin or malar projection, or through linear retrograde threading and fanning patterns using a 21G to 23G blunt micro-cannula to treat deep folds and jaw contours safely.

• Optimal Placement Depth: Must be placed cleanly within the deep subcutaneous fat layer or supra-periosteally. Shallow delivery in the superficial or mid-dermis must be strictly avoided, as the high density of this thick gel can cause hard visible lumps, uneven skin texture, or a bluish tint under the skin (Tyndall effect).

• Post-Injection Management: The injector should firmly mold and massage the treated areas immediately following delivery to blend the gel smoothly into natural facial contours. Patients may notice mild swelling, redness, or localized bruising. Advise them to avoid heavy exercise, alcohol, saunas, and applying heavy pressure to the treated zones for 24 to 48 hours.

FAQ

Q: Can Rejeunesse Shape be dissolved if a patient desires a correction?

A: Yes. Because Rejeunesse Shape is composed entirely of cross-linked hyaluronic acid, it can be quickly and completely dissolved using standard prescription hyaluronidase enzymes if a correction or complete reversal is needed.

Q: What makes Rejeunesse Shape different from Rejeunesse Deep?

A: The difference lies within the gel’s particle thickness and structural density. Rejeunesse Deep features a medium-density gel tailored for the mid-to-deep dermis, making it ideal for moderate wrinkles and full lip augmentation. Rejeunesse Shape is much denser and thicker, designed strictly for deep subcutaneous or bone-level placement to provide heavy structural lifting on the chin, cheeks, nose, and jawline.

Q: Can this product be used for lip fillers or under-eye hollows?

A: No. Rejeunesse Shape is strictly contraindicated for highly dynamic, thin-skinned facial zones like the body of the lips or the tear troughs. Its high density and thickness are highly prone to causing hard nodules, visible lumps, and asymmetry in those delicate regions.
