Arizona Tribune - Understanding When to Use Fillers or Neurotoxins According to Dr. Ran Rubinstein

MONTVALE, NEW JERSEY / ACCESS Newswire / January 30, 2026 / Injectable aesthetic treatments continue to grow in popularity, yet confusion remains around when dermal fillers are appropriate versus when neurotoxins are the better option. Facial plastic surgeon and national injectables trainer Dr. Ran Rubinstein emphasizes that understanding how these treatments differ is essential to achieving natural, balanced results.

As a board-certified facial plastic surgeon certified by the American Board of Facial Plastic and Reconstructive Surgery, Dr. Rubinstein notes that fillers and neurotoxins work through distinct biological mechanisms and must be selected based on facial anatomy, movement patterns, and long-term aesthetic goals.

Fillers and Neurotoxins Serve Different Purposes

Although both fillers and neurotoxins are injectable treatments, they address facial aging in fundamentally different ways.

Dermal fillers, most commonly injectable hyaluronic acid (HA) fillers, are designed to add volume, restore contour, or enhance facial definition. Neurotoxins, such as botulinum toxin products, work by relaxing targeted muscles to soften expression-related lines. While both treatments can improve the appearance of wrinkles, they do so through distinct processes that require different planning considerations.

Not All Dermal Fillers Are the Same

One of the most common misconceptions Dr. Rubinstein encounters is the belief that all injectable HA fillers function the same way. In practice, dermal fillers vary widely in texture, flexibility, and structural support, which is why careful product selection is essential.

Different HA fillers are selected based on:

• The specific area of the face being treated

• The amount of movement in that area

• Whether the goal is subtle refinement or structural support

Some fillers are soft and flexible to accommodate natural facial movement, while others provide firmer support for contouring and definition. Proper product selection allows results to look balanced and natural rather than overfilled. This individualized approach to dermal fillers reflects the importance of injector expertise and facial anatomy knowledge.

Biostimulators and HA Fillers Are Not Interchangeable

Another area of confusion involves biostimulators and their role in facial rejuvenation. While biostimulators and injectable hyaluronic acid (HA) fillers are often discussed together, they serve different purposes and are selected based on distinct treatment goals.

Biostimulatory injectables are designed to stimulate the body's natural collagen production over time. Rather than creating immediate volume, they support gradual structural improvement and skin quality changes as collagen develops. For many patients, this approach offers:

• More subtle, progressive enhancement

• Longer-lasting improvement driven by collagen remodeling

• A natural evolution of results over time rather than instant change

Because collagen production occurs gradually, biostimulatory treatments may require multiple sessions and patience before results are fully visible. They are often chosen for patients seeking long-term support rather than immediate contour correction.

Injectable HA fillers, by contrast, are frequently used when precise placement and immediate volume or definition are desired. Their ability to deliver targeted structural support makes them well suited for specific facial areas where contour and balance need to be addressed directly.

Understanding the complementary roles of biostimulators and HA fillers allows treatment plans to be tailored rather than standardized, ensuring each approach is used where it delivers the most appropriate and natural outcome.

Understanding Cost, Longevity, and Value

Concerns about cost often influence patient decision-making. Dr. Rubinstein notes that injectable treatments should be evaluated based on longevity, precision, and outcomes rather than upfront pricing alone.

Most injectable HA filler treatments are performed in-office in under an hour, with results that may last a year or longer depending on the product used and the treatment area. When considered over time, many patients find that the durability and quality of results justify the investment.

Fillers Are Used Beyond the Lips

Dermal fillers are frequently associated only with lip enhancement, but their applications extend far beyond that single area. Injectable HA fillers can be used to address a range of facial concerns, including:

• Under-eye hollowing

• Cheek contour and midface volume

• Lower facial lines and folds

• Chin structure and projection

Each treatment area requires careful evaluation of facial proportions and product selection to maintain harmony across the face.

The Key Difference Between Fillers and Neurotoxins

A foundational distinction Dr. Rubinstein emphasizes is how fillers and neurotoxins achieve their effects.

Fillers add volume or definition and often produce immediate visible changes. Neurotoxins reduce muscle movement, with results developing gradually over several days to weeks. While both treatments can smooth lines or wrinkles, they address different causes of facial aging and are frequently used together as part of a comprehensive treatment plan.

Expertise Matters in Injectable Treatment Planning

Dr. Rubinstein's approach to injectables is rooted in education, safety, and anatomical precision. As a national trainer, he works with medical professionals across the country to advance best practices in aesthetic injection techniques. This role underscores the importance of individualized treatment planning and ongoing education in a rapidly evolving field.
