If you’ve done any research before a filler consultation, you’ve probably encountered multiple brand names: Restylane, Revanesse, Juvederm, RHA Collection. They’re all hyaluronic acid fillers, which makes them easy to assume are interchangeable. They’re not. Different products within each line, and across lines, have meaningfully different physical properties that make them better suited for different treatment areas, different tissue types, and different patient goals.
At FACE/FIT, we carry the Restylane family, Revanesse, and the RHA Collection. This post explains what makes each distinct, where each performs best, and how we make the selection decision in practice. For the full overview of dermal filler treatment at FACE/FIT including treatment areas, what to expect, and how to book, see our Dermal Fillers service page.
What Makes HA Fillers Different From Each Other
All hyaluronic acid fillers share the same fundamental mechanism: the HA gel binds water molecules, adding volume and hydration to the tissue where it’s placed. What differs between products is the physical structure of the gel itself, which affects how the filler behaves in tissue.
Two properties matter most for clinical selection.
G-prime (gel stiffness): G-prime is the measure of a filler’s resistance to deformation. High G-prime fillers hold their shape under pressure, which makes them appropriate for structural support where the filler needs to maintain its placement under the movement and pressure of surrounding tissue, such as cheek augmentation or chin projection. Low G-prime fillers spread and integrate softly, which makes them appropriate for delicate areas where a natural feel matters more than structural rigidity, such as the lips or under-eyes.
Cohesivity: Cohesivity describes how well the gel holds together rather than spreading diffusely. Highly cohesive fillers stay where they’re placed. Less cohesive fillers integrate more with surrounding tissue. The right cohesivity depends on the treatment area and the desired result.
Understanding these properties is why filler selection matters and why the same brand used everywhere on the face, as some providers do, produces inferior results compared to matching the product properties to the area being treated.
The Restylane Family
Restylane has the longest clinical track record of the three lines we carry. The Restylane family uses NASHA (Non-Animal Stabilized Hyaluronic Acid) technology in its classic products, with more recent products using XpresHAn technology for increased flexibility.
The breadth of the Restylane line means there’s a specific product formulated for almost every facial area and concern:
Restylane-L is the classic midrange product, suitable for moderate facial lines and general volume correction. The L designation indicates the inclusion of lidocaine for improved comfort.
Restylane Lyft is a firmer, higher G-prime product designed for cheek augmentation and mid-face volume restoration where structural support is needed. It’s also FDA-approved for hand rejuvenation, making it one of the few fillers with a specific indication for this area.
Restylane Defyne uses XpresHAn technology for a flexible, natural feel that’s particularly well suited for deep nasolabial folds and areas where movement is pronounced. The flexibility means it doesn’t feel rigid or look placed when the face is in motion.
Restylane Refyne is a softer version of Defyne, suitable for moderate nasolabial folds and marionette lines where less correction is needed but natural flexibility in the result is still important.
Restylane Kysse is formulated specifically for lip augmentation, with XpresHAn technology that produces a flexible, soft, natural-feeling result. It’s designed to maintain natural lip movement rather than creating a stiff or overdone appearance.
Restylane Eyelight is formulated specifically for the under-eye tear trough area, with properties optimized for the thin, delicate tissue in this location.
When we reach for Restylane: Cheek augmentation with Lyft, lip enhancement with Kysse, tear trough correction with Eyelight, and dynamic areas like nasolabial folds with Defyne or Refyne. The line’s depth means we can choose a product precisely matched to what each area needs rather than adapting a general-purpose product to multiple uses.
Revanesse
Revanesse is manufactured by Prollenium and represents a newer generation of HA filler technology. The Revanesse line uses a proprietary cross-linking technology that produces what many clinicians describe as particularly natural tissue integration: the gel settles smoothly and uniformly into the surrounding tissue in a way that some patients and providers find more natural-feeling than some alternative products.
Revanesse Versa is the flagship product: a versatile, midrange filler that integrates well across multiple facial areas. Clinical data shows strong results for nasolabial folds and midface volume, and it has a notably favorable swelling profile compared to some HA fillers, with less post-treatment swelling in the days following injection.
Revanesse Lips+ is formulated specifically for lip augmentation with lidocaine, producing a soft, flexible result well suited for patients who prioritize natural feel and movement.
Revanesse Ultra provides firmer, more structural support for deeper volume correction and areas needing more significant structural filling.
When we reach for Revanesse: Patients who’ve had swelling reactions to other HA fillers often respond better to Revanesse due to its favorable swelling profile. Versa is our go-to for midface volume and nasolabial folds when natural tissue integration is a priority. Lips+ is a strong option for lip augmentation particularly in patients new to filler who want a soft starting result.
The RHA Collection
RHA stands for Resilient Hyaluronic Acid. The RHA Collection from Revance uses a manufacturing process that preserves longer HA chains and produces less cross-linking than traditional HA fillers. The result is a filler designed to mimic the natural HA in tissue more closely, with properties that allow it to move and flex dynamically with facial expressions rather than resisting them.
This is the defining characteristic of the RHA Collection: it’s designed for dynamic areas of the face where movement is constant and where traditional fillers can sometimes feel or look stiff when the face is in motion.
RHA 2 is the most delicate formulation, suited for fine lines and superficial corrections in dynamic areas.
RHA 3 is the midrange product, appropriate for moderate correction in highly dynamic areas including the perioral region and nasolabial folds.
RHA 4 provides more significant structural support while retaining the dynamic flexibility the line is known for, suitable for deeper correction and volume in areas that move significantly.
RHA Redensity is specifically formulated for the tear trough and periorbital area, with a formulation designed for the unique requirements of thin under-eye tissue.
When we reach for the RHA Collection: Dynamic areas are where RHA consistently outperforms standard HA fillers. Perioral lines (the fine lines around the mouth that develop with age and movement), nasolabial folds in patients with very expressive faces, and the periorbital area where RHA Redensity provides tear trough correction that behaves naturally with eye movement. For patients who’ve had filler before and found results looked good at rest but stiff or unnatural when smiling or talking, transitioning to RHA in those areas often resolves the issue.
How We Actually Decide
In practice, the selection decision for each patient and each area involves several factors considered together.
The treatment area: Certain areas have more defined ideal product characteristics. Lips benefit from low G-prime, high flexibility products. Cheeks need structural support from higher G-prime products. The tear trough needs products specifically formulated for thin tissue.
The degree of correction: A patient needing subtle refinement uses a different product than a patient needing significant volume restoration, even in the same area.
Your tissue characteristics: Tissue density, existing laxity, and how much underlying structural support is present affects which product properties will produce the best result for your specific face.
Your history with fillers: Patients who’ve had reactions, excessive swelling, or results that looked unnatural with specific products inform the selection. If a previous provider used a product that didn’t work well for your tissue, knowing what it was helps us make a better choice.
The overall treatment plan: If multiple areas are being treated, product selection considers how the results in each area will relate to each other and to the overall facial picture.
The consultation is where all of this comes together. We explain our reasoning before we start, so you understand what we’re using and why rather than just accepting a generic recommendation.
Frequently Asked Questions
Does it matter which HA filler brand is used?
Yes, meaningfully. Product properties including G-prime, cohesivity, and flexibility affect how filler behaves in tissue, how natural it feels, how much swelling it causes, and how well it performs in dynamic areas. Using the product best matched to each area and each patient produces better outcomes than a one-product-fits-all approach.
Can different fillers be used in different areas in the same appointment?
Yes, and this is common practice. A single facial balancing appointment might use Restylane Lyft for cheeks, RHA 3 for nasolabial folds, and Revanesse Kysse for lips, because each area benefits from different product properties.
What if I've had filler from another provider and want to switch products?
We assess the existing filler at your consultation. If previous filler has fully integrated or been metabolized, we work from a clean baseline. If previous filler is still present and contributing to the result, we discuss whether to build on it or dissolve and restart depending on the situation.
How do I know if my current filler has dissolved?
HA fillers typically metabolize within six to eighteen months depending on the product and location. Some patients metabolize filler faster than others. An assessment at your consultation can identify whether previous filler is still present and contributing to the current appearance.
Is one brand safer than another?
All FDA-approved HA fillers have comparable safety profiles when used by trained providers. The primary safety considerations are the qualifications of the injector and the appropriateness of the product for the area being treated rather than inherent differences in product safety across brands.
Want to understand which filler is the right choice for your specific goals and anatomy?
Book a consultation at FACE/FIT Houston. We’ll assess your facial structure, explain our product recommendation with the reasoning behind it, and build a treatment plan around what will actually produce the result you’re looking for.
