Dermal fillers at Dr. Kaga’s NJ practice go far beyond lip plumping. From restoring cheek volume and defining the jawline to softening facial folds and rejuvenating select areas affected by volume loss, Dr. Kaga personally administers every filler treatment — with an artist’s eye and a physician’s precision.
At The Kaga Institute in Marlboro and East Brunswick, NJ, filler isn’t about changing the way you look. Treatment is customized to your facial anatomy, proportions, natural aging patterns, and aesthetic goals to create balanced, natural-looking results.

What are dermal fillers?
Dermal fillers are injectable treatments used to restore or add volume, enhance facial contours, soften certain lines and folds, and improve facial balance.
Many popular fillers are made with hyaluronic acid (HA), a substance naturally present in the body that helps maintain hydration and volume in the skin. Other injectable products work differently and may contain ingredients such as calcium hydroxylapatite (CaHA) or poly-L-lactic acid (PLLA).
The right product depends on much more than the area being treated. Dr. Kaga considers your anatomy, tissue quality, degree of volume loss, desired correction, and treatment goals when selecting a filler.

What can dermal fillers treat?
Facial aging doesn’t happen in just one place. Over time, changes in skin, fat, bone, and other supporting structures can alter facial contours and contribute to folds, hollows, and loss of definition.
Depending on your anatomy and the product selected, dermal fillers in NJ may be used to address areas including:
Lips
Lip fillers can add volume, improve definition, enhance shape, or restore fullness that has diminished over time.
Dr. Kaga tailors treatment to your natural lip anatomy and facial proportions rather than using the same shape or amount of filler for every patient.
Cheeks
Age-related volume changes in the midface can contribute to flatter cheeks and changes in facial contours.
Cheek fillers can restore or enhance volume and help create more balanced definition through the midface.
Jawline
Jawline filler can be used to enhance definition and improve facial proportions in appropriately selected patients.
Treatment may focus on specific areas of the jaw rather than simply adding volume along the entire jawline.
Chin
Chin filler can improve projection, shape, and facial balance without surgery. It may also be combined with jawline or other facial contouring treatments when appropriate.
Tear Troughs
Hollowing beneath the eyes can create a tired appearance even when you’re well rested.
In carefully selected patients, tear trough filler may help improve under-eye hollowing. Because the under-eye area requires particularly careful assessment, Dr. Kaga will determine whether filler or another treatment is the better option for your anatomy.
Nasolabial Folds
Nasolabial folds are the lines that extend from the sides of the nose toward the corners of the mouth.
Rather than automatically injecting directly into the fold, Dr. Kaga evaluates the surrounding facial structure and volume loss to determine the most appropriate treatment strategy.
Temples
Volume loss in the temples can contribute to a hollow or more angular appearance. Carefully placed filler may help restore smoother contours and improve balance between the upper and midface.
Hands
The hands can also lose volume with age, making tendons and veins appear more prominent. Certain injectable fillers may be used to restore volume and create a smoother appearance in appropriate patients.
Facial contouring with dermal fillers
One of the biggest advantages of modern filler treatment is the ability to look at the face as a whole.
Rather than treating an isolated wrinkle or adding volume simply because an area looks hollow, Dr. Kaga considers how the cheeks, chin, jawline, lips, temples, and surrounding structures work together.
This approach to facial contouring in NJ can help create subtle improvements in proportion and definition while maintaining the features that make you look like you.
What types of dermal fillers does The Kaga Institute offer?
Different fillers have different formulations, characteristics, and intended uses. We offers multiple injectable options so treatment can be selected according to the patient’s anatomy and goals.
JUVÉDERM®
JUVÉDERM is a family of hyaluronic acid fillers with products designed for different facial areas and treatment goals.
Depending on the specific product, JUVÉDERM may be used for concerns such as facial volume loss, folds, facial contouring, or lip enhancement.
For patients considering JUVÉDERM in NJ, Dr. Kaga can recommend the appropriate product based on the area being treated and desired result.
Restylane®
Restylane is another family of hyaluronic acid fillers offering multiple formulations for different areas of the face.
Different Restylane products vary in characteristics such as flexibility, structure, and intended treatment area, allowing Dr. Kaga to select a product based on the type of correction needed.
Radiesse®
Radiesse is different from traditional hyaluronic acid fillers. It is made with calcium hydroxylapatite (CaHA) microspheres in a gel carrier and provides immediate correction while also stimulating collagen production.
It may be considered for certain facial contouring and volume-restoration treatments, as well as hand rejuvenation, depending on the patient’s needs.
Sculptra®
Sculptra works differently from a traditional filler. Its active ingredient, poly-L-lactic acid (PLLA), stimulates the body’s own collagen production to gradually improve facial volume and structure.
Results develop progressively rather than creating the same type of immediate correction associated with many HA fillers. Sculptra can be an option for patients seeking broader, gradual restoration of age-related facial volume loss.
This allows the product, amount, and placement to be customized rather than choosing filler based on a brand name alone.
What can I expect during filler treatment?
Your appointment begins with a facial assessment and discussion of what you’d like to improve. Dr. Kaga will evaluate your face from multiple angles and recommend the areas and products that may best accomplish your goals. Filler is then carefully injected into predetermined areas. Depending on the treatment, a topical numbing agent may be used for additional comfort, and many modern HA fillers also contain lidocaine. Treatment time varies depending on the number of areas being addressed and the complexity of the treatment plan.
Temporary swelling, tenderness, redness, or bruising can occur following injections. Dr. Kaga will provide specific aftercare instructions based on your treatment.
How long do dermal fillers last?
The duration of filler results varies considerably. Factors such as the specific product, treatment area, amount injected, your metabolism, and individual anatomy can all influence how long results remain visible. Some hyaluronic acid fillers may last several months to well over a year, while collagen-stimulating products have different treatment schedules and timelines.
During your consultation, Dr. Kaga can provide a more realistic expectation based on the specific product and area you’re considering.
Will my filler results look natural?
Natural-looking filler isn’t simply about using less product. It requires understanding facial anatomy, proportions, movement, and how the face changes with age.
Dr. Kaga’s goal is to enhance or restore your existing features rather than create a different face. Sometimes that means treating the area that concerns you directly. Other times, achieving a more natural result means addressing the underlying structural changes contributing to that concern.
As Dr. Kaga believes, looking better doesn’t mean you need to look different.
