Teoxane RHA fillers in Castle Rock, CO

A face is rarely still. It lifts into a smile and creases with a laugh dozens of times in a single conversation, and every one of those movements stretches the tissue around a dermal filler. A gel that looks beautiful in a resting photo can read as heavy or fixed once the face comes alive, and that gap between still and animated is where many filler results lose their polish.

Teoxane RHA was created to close that gap. This Swiss collection of hyaluronic acid fillers bends with your expressions and settles back into shape when your face relaxes, softening lines and replacing lost volume while your features keep their natural range of motion. At Colorado Integrative Health, our injectors pair each RHA formulation with the way a specific part of your face moves, from the fine lines around the mouth to the contours of the cheeks.

RHA was the first hyaluronic acid filler collection approved by the FDA specifically for dynamic facial wrinkles and folds,
the lines that deepen when you talk and smile. Newer approvals now extend the collection to the cheeks and to the hollows beneath the eyes.

What Makes RHA Different from Other Hyaluronic Acid Fillers?

Natural hyaluronic acid breaks down within a day or two, so every manufacturer links the molecule’s chains into a longer-lasting gel through a step called crosslinking. How that step is carried out determines how the finished product feels and behaves under the skin.

Teoxane uses a proprietary method called Preserved Network Technology, or PNT. It crosslinks the chains gently and without heat, using a comparatively light hand with the crosslinking agent. According to Teoxane, this preserves more of the long natural chains and gives the gel a structure that blends smoothly into tissue and moves the way living tissue moves.

Why does stretch matter in a filler?

Injectors often describe fillers by their firmness, measured as G′ and pronounced “G prime.” Firm gels hold their shape under pressure, which is valuable deep along the cheekbone. The face, however, spends very little of the day at rest. Teoxane’s researchers introduced two further measures, which they called strength and stretch, to capture how a gel behaves while the face is moving.

RHA gels score high in stretch. They flex with a smile and return to their original form afterward, avoiding the ridged or displaced look that can appear when a stiff gel sits in an expressive area.

Quick takeaway: Firmness tells you how well a filler holds its shape at rest. Stretch tells you how gracefully it moves with you. RHA was engineered for the second quality, which is why it performs so well in the most expressive parts of the face.

Why does RHA contain mepivacaine?

The RHA products available in the United States contain mepivacaine, a local anesthetic closely related to lidocaine, blended directly into the gel. Numbing begins as the product is placed, so most patients find treatment far more comfortable than they expected. Revance reports that the anesthetic has no meaningful effect on the gel’s properties or on how long it lasts.

Which RHA Filler is Right for Each Area of Your Face?

The collection includes several formulations, each approved for a particular depth and purpose. Softer gels sit close to the surface where skin is thin, while denser gels go deeper to rebuild structure. A single treatment plan frequently combines two of them in one visit.

RHA Redensity for lines around the mouth

RHA Redensity is the most delicate gel in the line, designed for the superficial layers of the skin. It is approved for moderate to severe dynamic perioral lines, the fine vertical creases above the upper lip that deepen each time you speak or purse your lips. Because it spreads so evenly, it softens those lines without adding visible bulk to the lip itself.

RHA 2 for moderate smile lines

RHA 2 is placed in the mid to deep dermis to correct moderate to severe dynamic wrinkles and folds. It suits smile lines that are noticeable yet still fairly shallow, and it is a natural choice for patients who want a refined change and nothing more.

RHA 3 for deeper folds and fuller lips

RHA 3 shares the folds indication of RHA 2 with a little more body, and it is also approved for lip augmentation. Lips are in motion through every word and every meal, which makes stretch especially valuable here. RHA 3 can add fullness and sharpen the lip border while the lips keep a soft, natural feel when you talk or smile.

RHA Dynamic Volume for the cheeks and midface

RHA Dynamic Volume is the most robust member of the collection. It received FDA approval in 2026 for cheek augmentation and age-related midface contour loss, and it is also approved for deep dynamic folds. Placed as deep as the bone, it rebuilds the support that thins across the cheeks with time. Restoring that foundation often softens the smile lines beneath it, and the gel is designed to rise naturally with the cheeks when you smile.

RHA Redensity Eye for under-eye hollows

RHA Redensity Eye is the newest addition, approved in 2026 for moderate to severe volume loss beneath the eyes in adults 22 and older. The under-eye area has thin skin and little room for error, and it moves with every blink and squint. Teoxane designed this soft, spreadable gel to smooth hollows while adapting to that constant motion, with results that can last up to a year.

How do the RHA formulations compare?

The table below summarizes where each product fits. Your provider will recommend formulations based on your anatomy and goals.

Formulation FDA-approved for Gel character Placement depth
RHA Redensity Fine dynamic lines around the mouth Softest and most spreadable Superficial dermis
RHA Redensity Eye Volume loss under the eyes Soft, adapts to blinking and squinting Beneath the skin to the bone surface
RHA 2 Moderate to severe dynamic wrinkles and folds Light and flexible Mid to deep dermis
RHA 3 Dynamic wrinkles and folds, plus lip augmentation Medium body with high stretch Mid to deep dermis and the lips
RHA Dynamic Volume Deep folds, cheek augmentation and midface contour Most robust, with the greatest lift Deep dermis down to the bone

How long do RHA results last?

You will see a difference as soon as your appointment ends. Some swelling is normal at first, and the final result settles in over about two weeks.

Longevity depends on the formulation and the area treated, along with your own metabolism. In clinical studies, RHA results in the smile lines held for up to 15 months, and RHA Redensity Eye lasted up to 12 months under the eyes. Lips tend to fall at the shorter end of any range, since they move with nearly every word. Many patients schedule a smaller touch-up as results begin to soften, which keeps the effect steady without starting over.

RHA’s durability has been tested head to head. In a 15-month randomized, double-blind, split-face trial of 140 adults with moderate to severe nasolabial folds, the side treated with RHA 4 showed significantly greater wrinkle improvement than an established hyaluronic acid comparator throughout the study (source).Does GetHairMD Work for Women as Well as men?

Who is a good candidate for RHA fillers?

RHA is approved for adults 22 and older, and it tends to suit people whose lines deepen with expression or whose faces are especially animated. It is also a thoughtful choice for anyone who has had filler before and felt it looked heavy when they smiled. Patients with mild to moderate volume loss usually see the most natural improvement.

Your provider will review your full health history first. RHA should be avoided by anyone with a history of severe allergic reactions, including allergy to amide anesthetics such as lidocaine, and by people with bleeding disorders. Its safety during pregnancy and breastfeeding has not been studied, so treatment is postponed during those times.

Can RHA restore facial volume lost during weight loss?

Rapid weight loss often shows first in the face. Patients using weight loss injections in Castle Rock, CO commonly notice flatter cheeks and deeper hollows under the eyes, sometimes before the scale has finished moving. RHA Dynamic Volume and RHA Redensity Eye address exactly these areas. Many patients find it worthwhile to begin once their weight has stabilized, so the correction matches the face they will keep.

Is RHA a good option for men?

Men often hesitate over filler because they worry about looking “done,” and a gel that moves with expression helps answer that concern. Cheek support and softer smile lines can make a face look rested while its character stays fully intact.

What happens during an RHA appointment?

How does your consultation work?

Your provider will study your face in motion as well as at rest, asking you to talk and smile to see where lines form and where volume has thinned. An Alma IQ skin analysis in Castle Rock can add an objective view of several skin layers at once, which helps separate volume loss from texture or laxity concerns that call for a different treatment. From there, you will agree on a plan, including which RHA formulations to use and how many syringes your goals require.

What does the treatment feel like?

Topical numbing may be applied first, and the mepivacaine within the gel takes over as product is placed. Most patients describe pressure and the occasional brief pinch. Your injector shapes and evaluates as they go, with you sitting upright so the result can be checked against your natural expressions. Most appointments take under an hour.

What should you expect after treatment?

Mild swelling, tenderness or bruising at the injection sites is common, and most of it fades within a few days. In clinical studies, the majority of side effects resolved within 14 days. You can return to work and most daily plans right away. For the first 24 hours, a little care goes a long way:

  • Skip strenuous exercise and alcohol, since both can increase swelling and bruising.
  • Stay out of extended sun and heat, including saunas and hot yoga, and avoid pressing on treated areas unless your injector asks you to.
Your RHA Treatment at a Glance
Appointment Length Usually under an hour, consultation included
Comfort Mepivacaine blended into the gel, with optional topical numbing
Results Visible immediately, fully settled in about two weeks
Downtime Minimal, with possible mild swelling or bruising
Longevity Up to 12 to 15 months in studied areas, shorter in the lips

How does RHA compare with Juvéderm and Restylane?

All three are well-studied, reversible hyaluronic acid fillers, and each family has its own strengths. Several Juvéderm gels are known for firmness and longevity in structural areas such as the cheeks and jawline. Restylane spans firm lifting gels as well as flexible ones built for movement. RHA’s distinction is stretch, which makes it a natural fit for the most expressive parts of the face.

We offer Juvéderm and Restylane fillers in Castle Rock alongside RHA, so your plan can draw on whichever product suits each area best. Our guide to how RHA compares with other leading fillers covers the differences in more depth.

Is RHA filler safe?

Every RHA formulation is FDA-approved for its labeled uses, and hyaluronic acid fillers have a long safety record. Reversibility is a key advantage. If a result ever needs refining, an enzyme called hyaluronidase dissolves the gel.

The most serious risk with any filler is accidental injection into a blood vessel. It is rare, yet it calls for immediate recognition and treatment, which is why the choice of injector matters more than the choice of brand. Our team works with detailed knowledge of facial anatomy and keeps hyaluronidase on hand at every appointment. Delayed inflammation near the treatment site can occasionally appear weeks later, sometimes after an illness or dental work, so let us know if anything changes after your visit.

Can RHA be combined with other treatments?

Filler restores volume and support, and other concerns respond better to other tools. Lines driven by muscle contraction, such as forehead creases and crow’s feet, typically call for a neuromodulator, and our article on fillers vs. neurotoxins explains how the two work together. For loose or crepey skin along the lower face, Sofwave skin tightening in Castle Rock builds collagen with ultrasound while RHA replaces the volume underneath.

Sequencing matters. RHA labeling notes a possible risk of inflammation when laser treatments or chemical peels follow filler, so we typically schedule resurfacing and energy-based treatments first, or space the two apart. Patients focused on texture and tone can pair RHA with Rejuvapen microneedling with PRP in Castle Rock, CO on a coordinated timeline.

Why choose Colorado Integrative Health for RHA fillers?

Natural filler results depend on judgment as much as product. Our injectors assess how your face moves before recommending anything, and because we offer RHA alongside Juvéderm and Restylane, every syringe in your plan is chosen for its area rather than out of loyalty to a single brand.

As an integrative practice, we also look at the larger picture. Hormonal shifts and weight changes both reshape the face over time, and services such as bioidentical hormone therapy in Castle Rock let us address those factors under the same roof. Patients come to our Castle Rock clinic from across Douglas County and the greater Denver area.
