Description

Juvéderm Ultra 4 is an injectable cross-linked hyaluronic acid filler from the Juvéderm Ultra family, specifically engineered for the treatment of deep skin depressions and significant volume restoration. Developed by Allergan Aesthetics, this formulation is the most robust and viscous of the Ultra series. It is designed to be injected into the deep dermis to address severe folds and to provide structural enhancement to the facial contours. Utilizing Hylacross technology, Ultra 4 provides a smooth yet highly stable gel that offers a reliable and natural-looking correction for more advanced signs of aging.

Main Benefits of Juvéderm Ultra 4

Hylacross™ Technology

Unlike the Vycross range, the Ultra series uses Hylacross technology to produce a highly cross-linked, robust, and smooth-consistency gel. This allows for a high concentration of Hyaluronic Acid that is resistant to immediate degradation, providing a stable “cushion” effect in the deep dermal layers.

Correction of Deep Depressions

Ultra 4 is specifically calibrated for the most challenging facial folds. Its density makes it highly effective at “pushing out” deep wrinkles that lighter fillers cannot adequately address, providing an immediate smoothing effect on the skin’s surface.

Natural Structural Enhancement

While it is a dense filler, Juvéderm Ultra 4 maintains the characteristic “smoothness” of the Juvéderm brand. It integrates well into the deep tissue, allowing for structural enhancement (such as chin or cheek contouring) that feels soft to the touch and moves naturally with facial expressions.

Maximum Patient Comfort

The “Ultra” range features integrated 0.3% Lidocaine. This local anesthetic ensures that the injection of this denser gel is as comfortable as possible for the patient, reducing the need for additional topical or nerve block anesthesia.

Indications

Juvéderm Ultra 4 is the go-to solution for deep-tissue correction:

• Deep Nasolabial Folds: Filling the heavy lines between the nose and mouth.

• Marionette Lines: Correcting deep folds at the corners of the mouth and chin.

• Cheek Augmentation: Restoring volume to the malar area.

• Chin and Jawline Contouring: Defining the lower facial profile.

• Facial Volumization: Correcting significant age-related volume loss in the mid-face.

Technical Specifications

Mechanism of Action

Ultra 4 works through Deep Dermal Volumization:

1. Immediate Filling: The high-density HA gel immediately occupies space within the deep dermis, elevating the depression caused by deep wrinkles or volume loss.

2. Structural Support: The Hylacross matrix provides a stable support system for the overlying skin, preventing the “collapsing” effect of deep folds.

3. Water Retention: The HA molecules attract moisture, keeping the treated area hydrated and improving the skin’s overall suppleness.

Administration Protocol

• Technique: Linear retrograde, fanning, or bolus injections.

• Depth: Must be injected into the deep dermis.

• Professional Note: Due to its viscosity, careful aspiration is recommended. It should not be used in the superficial dermis or peri-orbital area (tear troughs) due to the risk of lumps or the Tyndall effect.

• Post-Care: Standard filler precautions apply: avoid pressure, high heat (saunas), and vigorous exercise for the first 24–48 hours.

FAQ

Q: How does Ultra 4 differ from Juvéderm Ultra 3?

A: Ultra 3 is designed for medium wrinkles and lip volume, while Ultra 4 is denser and specifically intended for deep folds and structural volumization of the cheeks and chin.

Q: Is there any downtime?

A: Minor swelling and redness are common immediately after injection but typically resolve within 2 to 5 days. Bruising may occur but can be minimized with proper technique and post-care.

Q: Can I use Ultra 4 in the lips?

A: Ultra 4 is generally considered too thick for the lips and may result in an unnatural feel. Ultra 3 or the Volbella/Volift range are typically preferred for lip treatments.
