With so many products and fillers on the market, it can be challenging to keep up with the names and what these products do. As an aesthetic practitioner, it is my duty to ensure that my patients know what I’m injecting into their face and why they’re getting it. Today, I want to talk about the difference between hyaluronic acid-based fillers (such as Juvéderm® and Restylane®) versus Sculptra®. While they both act to replace volume, they have different mechanisms of action, timelines for results, and indications. There are many considerations to assess when determining who is a candidate for Sculptra® or hyaluronic acid-based fillers.
Hyaluronic Acid-Based Fillers
Hyaluronic acid (HA) fillers are among the most popular injectables on the market today. These fillers are gel-like substances composed of hyaluronic acid, a naturally occurring substance in our skin that helps maintain hydration and volume. HA fillers are versatile and can be used to address a variety of aesthetic concerns, including smoothing wrinkles, adding volume to lips, and contouring facial features.
Mechanism of Action: HA fillers work by physically filling the space where volume has been lost. They attract water to the injected area, which helps to maintain the plumpness and smoothness of the skin.
Rheology: When choosing an HA filler, understanding its rheology, or how it behaves under stress, is essential. HA fillers vary in their G-prime, which refers to the product’s elasticity or “stiffness.” A higher G-prime means the filler is firmer, making it better suited for areas requiring more structural support, such as the cheeks. Lower G-prime fillers are softer and are often used in areas like the lips where a softer, more natural feel is desired.
Hydrophilic Properties: HA fillers are hydrophilic, meaning they attract and retain water, which can enhance their volumizing effect. This property is advantageous for areas where additional volume is needed, but it also means that HA fillers may cause some swelling immediately after injection.
Timeline of Results: HA fillers provide immediate results, which can last anywhere from 6 to 18 months, depending on the specific product used and the area treated. They can also be reversed with hyaluronidase if necessary, making them a safe and flexible option for patients.
Sculptra®
Sculptra®, on the other hand, is a unique injectable that works differently from HA fillers. It is made from poly-L-lactic acid (PLLA), a biodegradable synthetic substance that has been used for many years in dissolvable stitches and other medical applications. Unlike HA fillers, which provide immediate volume, Sculptra® works gradually by stimulating the body’s own collagen production.
Mechanism of Action: Sculptra® acts as a collagen stimulator rather than a filler. When injected into the skin, it triggers a response that leads to the production of new collagen over time. This helps to restore facial volume lost due to aging or illness.
Treatment Protocol: Best results with Sculptra® are usually seen after a series of treatments, typically spaced 4 to 6 weeks apart. While HA fillers provide instant results, the effects of Sculptra® develop gradually over a few months as collagen builds up in the treated areas. Patients can expect to see the optimal results around six months after their initial treatment, with effects lasting up to two years or more.
Historical Use: Sculptra® was initially approved for the treatment of lipoatrophy in HIV-positive patients, a condition that causes severe facial fat loss and muscle wasting. This history highlights how effective Sculptra® in restoring lost volume and creating a more youthful appearance.
Which One is Right for You?
Choosing between HA fillers and Sculptra® depends on your specific aesthetic goals, the treatment area, and various patient-specific factors. When assessing a patient for facial volume restoration, I take into account several key aspects, including skin quality, laxity, the amount of facial fat or fullness, lifestyle, previous treatments, and the specific area of concern. For example, patients with less facial fat and significant volume loss may benefit more from Sculptra®, which gradually stimulates collagen production to restore fullness. On the other hand, if you’re looking for immediate results and prefer a product that can be easily adjusted, HA fillers such as Juvéderm® or Restylane® might be the best choice. However, if you’re seeking a more gradual, long-lasting improvement and are willing to commit to a series of treatments, Sculptra® could be the ideal option.
At the end of the day, both HA fillers and Sculptra® are excellent products in the world of aesthetics, but their use must be carefully tailored to each patient’s unique needs. By understanding the differences between these treatments, you can make an informed decision about which option is right for you.
