Most filler consultations begin with a brand name. A friend had Juvéderm placed in her cheeks and loved the result, or an injector on social media keeps tagging RHA in before-and-after posts. The name arrives first, and the question of what the face in the mirror actually needs tends to arrive second.
That order is understandable, but it is backwards. All three product families are built from hyaluronic acid and approved by the U.S. Food and Drug Administration, and in experienced hands each can produce a natural-looking result. What separates them is manufacturing. Every company links its hyaluronic acid chains together with its own process, and that process decides how firm the gel feels and how it behaves when your face moves. Those physical traits, far more than the logo on the syringe, determine which product belongs in your lips and which belongs along your cheekbones.
This guide walks through how each family is made and where each one tends to earn its place, so the conversation at your dermal fillers in Castle Rock, CO consultation can start with your goals instead of a brand preference.
What do RHA, Juvéderm, and Restylane have in common?
Hyaluronic acid is a sugar molecule that occurs naturally in the skin, where it binds water and keeps tissue plump. In its natural form it breaks down within a day or two, far too quickly to hold a cosmetic correction. Manufacturers solve that problem through crosslinking, a chemical step that bridges long hyaluronic acid chains into a stable gel network able to resist the enzymes that would otherwise dissolve it. All three brands use the same crosslinking agent, known as BDDE (1,4-butanediol diglycidyl ether), though each applies it differently.
Because the base material is shared, so are several practical traits. Results are visible immediately, and the final look settles once swelling fades over roughly two weeks. Most current formulations include a local anesthetic mixed into the gel, lidocaine in the case of Juvéderm and Restylane and mepivacaine in the current U.S. versions of RHA, which makes injection noticeably more comfortable. Hyaluronic acid can also be dissolved with an enzyme called hyaluronidase if a result ever needs adjusting, a safety margin that permanent and semi-permanent fillers lack.
Hyaluronic acid fillers remain one of the most requested aesthetic treatments in the country. The American Society of Plastic Surgeons recorded 5,331,426 hyaluronic acid filler procedures in 2024, a 1% increase over the prior year, ranking them second among minimally invasive treatments behind neuromodulators (source).
For a broader primer on what filler can do before comparing brands, our overview of how dermal fillers restore volume covers the fundamentals.
What is Teoxane RHA, and why is it built for movement?
Teoxane is a Swiss company founded in Geneva in 2003 by Valérie Taupin, and it has built its entire portfolio around hyaluronic acid. RHA stands for Resilient Hyaluronic Acid, a name that points directly at the design goal. The gels are produced with a proprietary process called Preserved Network Technology, which crosslinks the hyaluronic acid gently and without heat. According to Teoxane, the method keeps more of the long, natural chains intact while using a comparatively light hand with the crosslinker.
The result is a gel that stretches and recoils with facial expression, and that property has shaped the line's regulatory history. In 2017, the original RHA gels became the first hyaluronic acid fillers approved by the FDA specifically for dynamic facial wrinkles and folds, meaning the lines that deepen when a person talks or laughs.
Revance distributes the collection in the United States, and the lineup has expanded quickly. RHA Redensity treats fine lines around the mouth, while RHA 2 and RHA 3 address moderate to severe dynamic wrinkles and folds, with RHA 3 also approved for lip augmentation. RHA Dynamic Volume, the product formerly sold as RHA 4, gained an FDA approval for cheek augmentation and midface contour loss in January 2026. In August 2026 the agency approved RHA Redensity Eye for hollowing beneath the eyes. Across their pivotal studies, RHA products have generally shown results lasting about 12 to 15 months, depending on the product and the area treated.
What is Juvéderm, and what makes its gels different?
Juvéderm is manufactured by Allergan Aesthetics, a division of AbbVie, and it is one of the most recognized names in American aesthetics. The family rests on two manufacturing platforms. Hylacross uses high molecular weight hyaluronic acid to create smooth, cohesive gels such as Juvéderm Ultra XC and Ultra Plus XC, which have long been used in lips and smile lines. Vycross blends low and high molecular weight hyaluronic acid, an approach that allows more efficient crosslinking and tends to draw in less water after injection, which means less post-treatment puffiness in many patients.
Vycross is the technology behind the Juvéderm products patients most often request by name. Voluma XC lifts and contours the cheeks and chin, and in the cheeks it is FDA-approved to last up to two years, among the longest durations available in a hyaluronic acid filler. Vollure XC softens moderate to severe folds around the nose and mouth. Volbella XC is the lightest of the group, used for understated lip definition and also approved for hollows under the eyes. At the firm end of the range, Volux XC was developed specifically to sharpen the jawline.
What is Restylane, and why does it come in so many textures?
Restylane has the longest history of the three in the U.S. market. Developed by the Swedish company Q-Med and now owned by Galderma, it became the first hyaluronic acid dermal filler approved by the FDA, in 2003. Galderma divides the line between two technologies with noticeably different personalities.
NASHA, short for non-animal stabilized hyaluronic acid, produces firmer gels with a strong capacity to lift and hold a precise shape. Restylane Lyft and the under-eye product Restylane Eyelight both belong to this group, and injectors often choose them when a result needs crisp projection or a clean edge.
The newer platform, marketed as XpresHAn Technology in the United States and as Optimal Balance Technology elsewhere, produces softer, more flexible gels designed to move with expression. Restylane Kysse for lips and Restylane Contour for the cheeks come from this platform, as do Refyne and Defyne, which are widely used for smile lines. Most Restylane products last roughly six to twelve months, with the exact figure depending on the product and placement.
Both of these established families are part of our Juvéderm and Restylane filler treatments in Castle Rock, which gives our injectors a wide range of textures to match to each area of the face. If RHA is the product you have in mind, raise it at your consultation so the discussion can cover how it compares for your specific goals.
How do RHA, Juvéderm, and Restylane compare side by side?
The table below summarizes the differences patients ask about most. Product details reflect current U.S. approvals.
What do G′ and "stretch" actually mean for your face?
The real divergence between these brands comes down to rheology, the branch of physics that studies how materials deform and flow. The figure injectors cite most often is G′, pronounced "G prime" and formally called the elastic modulus. It describes how firmly a gel resists being compressed. A high-G′ gel behaves like a dense cushion and holds its shape under pressure, which is useful deep along the cheekbone or chin, where filler has to stand in for lost bone and fat support. A low-G′ gel is softer and spreads more readily, which suits thin skin and shallow placement.
G′ measures firmness at rest, and a face spends very little of the day at rest. Every conversation and every smile stretches the tissue around a filler in several directions at once. Researchers at Teoxane proposed two additional measures, called strength and stretch, arguing that they predict how a gel will behave during facial animation more accurately than G′ alone. RHA gels score high on stretch, which is the scientific basis for their reputation in expressive areas. Restylane's XpresHAn gels and Juvéderm's Volbella XC were also engineered with movement in mind, so the gap between brands narrows considerably depending on which specific products are compared.
Quick takeaway: Firm gels hold their shape and do their best work deep, where they replace lost structure. Stretchy gels move with expression and perform best where the face is always in motion. Most faces need some of each, which is why many treatment plans use more than one product.
Which filler tends to suit which part of the face?
Each area of the face places its own demands on a gel, and certain products line up with those demands better than others. A useful rule of thumb shapes most injector decisions:
- Areas that provide structure, such as the cheekbones, chin, and jawline, usually call for firmer gels with a higher G′.
- Areas that move constantly, such as the lips and the lines around the mouth, usually call for softer gels with more stretch.
Which filler works best for lips?
Lips move almost continuously, and they are unforgiving of stiff product. Restylane Kysse and RHA 3 are both approved for lip augmentation, and both are designed to move naturally when you speak or smile. Juvéderm Volbella XC is often the pick for patients who want the most understated change, such as a crisper border or softened vertical lip lines.
What about the cheeks and midface?
Structure matters most here. Juvéderm Voluma XC holds the longest approved duration in the cheeks, and Restylane Lyft and Restylane Contour offer alternatives at different levels of firmness. RHA Dynamic Volume is the newest option, approved in 2026 for midface contour and designed to restore volume without looking rigid when the cheeks lift in a smile.
Which fillers are approved for under the eyes?
The tear trough has thin skin and very little margin for error, so injectors favor soft, low-swelling gels placed with care. Restylane Eyelight and Juvéderm Volbella XC have carried FDA approval for under-eye hollows for several years, and RHA Redensity Eye joined them in August 2026. Patients who lose facial fat quickly, including many using weight loss injections in Castle Rock, CO, often notice hollowing in this area first.
What about the jawline and chin?
Firm, high-G′ gels are the standard tools along the lower face. Juvéderm Volux XC was developed specifically for jawline definition, and Voluma XC is approved for chin augmentation. Both hold a defined edge well, which matters in an area where a soft gel can look blurred.
Which filler is best for smile lines and lines around the mouth?
This is where RHA built its reputation. The collection was approved first for dynamic folds, and RHA Redensity remains one of a small number of products approved specifically for fine lines around the mouth. Restylane Refyne and Defyne and Juvéderm Vollure XC are also widely used for nasolabial folds, and the choice among them often comes down to how deep the fold is and how much the area moves.
Does one brand last longer than the others?
Longevity is the most misunderstood part of filler marketing. Label durations come from clinical trials, where patients often receive generous volumes and a planned touch-up under controlled conditions. In everyday practice, how long a filler lasts depends on the density of the gel, the area treated, how much that area moves, and the individual's own rate of breakdown. A firm gel placed deep in the cheek, which moves relatively little, will usually outlast a soft gel in the lips, which move every time you eat or talk.
By label, Juvéderm Voluma XC holds the headline figure at up to two years in the cheeks. RHA products have typically shown about 12 to 15 months, and many Restylane products fall between six and twelve months. Within the same area of the face, the real-world gap between brands tends to be smaller than those numbers suggest, and precise placement often contributes more to longevity than the brand itself.
How will your injector decide which filler is right for you?
A good filler consultation begins with the face, and the product list comes later. An experienced injector looks at skin thickness and the pattern of volume loss, then watches how the face moves during conversation. Prior treatments matter too, including any history of lumps or reactions to earlier fillers. An Alma IQ skin analysis in Castle Rock adds objective data to that assessment by imaging several layers of the skin at once, which helps separate volume loss from texture and laxity concerns that filler cannot fix.
The plan that comes out of that assessment frequently uses more than one product. A patient might leave with a firm Vycross or NASHA gel along the cheekbones and a softer, stretchier gel in the lips, all in the same appointment. Cost tends to depend more on how many syringes a plan requires than on which brand is chosen, since pricing across the major families is broadly comparable.
Safety deserves a plain mention. Hyaluronic acid fillers have a strong safety record, and the most common side effects are temporary swelling and bruising. The most serious risk, accidental injection into a blood vessel, is rare but requires immediate recognition and treatment. That risk is best managed by a medical injector with detailed knowledge of facial anatomy who keeps hyaluronidase on hand, and it is a better reason to choose a provider carefully than any difference between brands.
Can fillers be combined with other treatments?
Filler restores volume and support. Lines driven by repeated muscle contraction, such as forehead creases and crow's feet, usually respond better to a neuromodulator, and our comparison of fillers vs. neurotoxins explains how the two work together. Loose or crepey skin calls for a collagen-building treatment instead. For patients whose lower face has softened along with losing volume, Sofwave skin tightening in Castle Rock addresses the laxity while filler replaces what has been lost underneath, and the two are commonly sequenced a few weeks apart.
The bottom line
Teoxane RHA, Juvéderm, and Restylane are all well-studied, reversible hyaluronic acid fillers with long clinical track records, and none of them is the right answer for every face. RHA stands out for stretch in expressive areas, and Juvéderm's Vycross gels are hard to beat for longevity in structural zones. Restylane sits across both camps, with firm NASHA gels for lift and flexible XpresHAn gels for movement.
The better question to bring to a consultation is which gel properties your anatomy needs in each area. Structure calls for firmness and motion calls for stretch. The brand on the syringe matters far less than the match between product and placement, and the judgment of the person holding it.
