The RHA collection built its reputation on a formulation approach that behaves differently from standard cross-linked gels once it sits in moving tissue. Teoxane holds a firm position in the hyaluronic acid filler market, and its Teosyal RHA line ranks among the dermal fillers practitioners request most in 2026.
The Story Behind Teosyal
Teosyal is manufactured by Teoxane Laboratories, which opened in Geneva, Switzerland in 2003, founded by biochemist Valerie Taupin to focus exclusively on hyaluronic acid research. The company built its early catalog around the classic Teosyal PureSense range before shifting attention to a new crosslinking method meant to solve a common complaint from injectors: fillers that looked stiff once a patient smiled, spoke, or chewed.
That research led to the RHA collection, which earned FDA approval starting in 2017 and reached the U.S. market at scale through a solid distribution partnership. Teoxane now distributes its fillers to more than 80 countries and reports tens of millions of syringes sold worldwide. Health Canada has cleared the RHA range as well, giving practitioners regulatory confidence on both sides of the border.
RHA Technology and Formulation
Most hyaluronic acid fillers rely on heavy crosslinking to slow degradation, but that process also strips out much of the HA’s natural flexibility. Teoxane’s Preserved Network Technology takes a different route. It keeps long, unmodified HA chains intact and adds only the crosslinking needed to give the gel enough structure for injection. The result is a gel that stretches, compresses, and returns to its original shape instead of resisting movement.
Every product in the RHA line uses this method, with hyaluronic acid concentrations that stay close to 19 to 23 mg/mL across the lineup. BDDE remains the crosslinking agent, the same one used across most major HA brands, but Teoxane uses far less of it per gram of HA. That lower crosslinking ratio is why Teosyal RHA fillers hold up well in high-motion areas like the lips and nasolabial folds, where stiffer gels can look unnatural mid-expression.
Teosyal Certifications
Most of the Teosyal line, including the RHA family of fillers and Redensity II PureSense, holds an active Health Canada licence as a Class 3 medical device. That classification means Health Canada reviewed the products before authorizing their sale, confirming they meet the required standards for safety and effectiveness. Combined with FDA clearance in the United States, that dual review gives practitioners added regulatory confidence when bringing Teosyal into a treatment menu.
5 Top Teosyal Fillers for Your Practice
Teoxane’s RHA collection anchors the Teosyal catalog available through Cosmo Direct Supply, and these five products cover the treatment zones practitioners request most in 2026. Below are the top Teosyal fillers ranked by how often clinics reorder them, from finer dynamic lines to deeper volume loss.
RHA 2 Lidocaine
Discount structure
- 1 - 4 packs - $178.00 each
- 5 - 9 packs - $172.66 each
- 10 - 19 packs - $169.10 each
- 20 - 29 packs - $163.76 each
- 30+ packs - $160.20 each
Teosyal RHA 2 Lidocaine targets moderate dynamic wrinkles, including early nasolabial folds and other areas that move constantly through the day. Its 23 mg/mL hyaluronic acid concentration and medium gel consistency let it settle into the mid-to-deep dermis without adding bulk the surrounding tissue would resist.
Built-in lidocaine keeps injections comfortable, and results typically hold for up to 12 months. Practitioners reach for RHA 2 when a patient wants correction without a heavier, more structured gel.
RHA 3 Lidocaine
Discount structure
- 1 - 4 packs - $191.00 each
- 5 - 9 packs - $185.27 each
- 10 - 19 packs - $181.45 each
- 20 - 29 packs - $175.72 each
- 30+ packs - $171.90 each
RHA 3 Lidocaine steps up in viscosity from RHA 2 to handle deeper nasolabial folds, marionette lines, and lip augmentation in the same 23 mg/mL formulation. The added structure supports tissue that has lost more volume while still flexing with normal facial expression.
Lidocaine is built into the formula, and correction lasts approximately 12 to 15 months depending on the treatment area. RHA 3 works well as a mid-tier option between RHA 2 and the heavier RHA 4.
RHA 4 Lidocaine
Discount structure
- 1 - 4 packs - $206.00 each
- 5 - 9 packs - $199.82 each
- 10 - 19 packs - $195.70 each
- 20 - 29 packs - $189.52 each
- 30+ packs - $185.40 each
RHA 4 Lidocaine is the thickest gel in the RHA range, built for cheek augmentation and midface contour loss. The same 23 mg/mL hyaluronic acid base carries more crosslinking than RHA 2 or RHA 3, giving it the lift needed to support sagging tissue in the cheeks and jawline.
Comfort stays built in through lidocaine, and effects last up to 15 months in most patients. Clinics stock RHA 4 for volume restoration cases that need more than a wrinkle filler can offer.
Teosyal RHA Kiss Lidocaine
Discount structure
- 1 - 4 packs - $135.00 each
- 5 - 9 packs - $130.95 each
- 10 - 19 packs - $128.25 each
- 20 - 29 packs - $124.20 each
- 30+ packs - $121.50 each
Teosyal RHA Kiss Lidocaine shares its composition with RHA 2 but comes in a smaller 0.7 mL syringe with a lower 19 mg/mL HA concentration, purpose-built for the lips. The softer gel reshapes the lip border and adds volume without the stiffness that can make lips look overfilled.
Perioral fine lines respond well to RHA Kiss too, and the smaller volume makes it a practical choice for first-time lip patients or subtle touch-ups. Results last close to 12 months.
Redensity II PureSense
Discount structure
- 1 - 4 packs - $185.00 each
- 5 - 9 packs - $179.45 each
- 10 - 19 packs - $175.75 each
- 20 - 29 packs - $170.20 each
- 30+ packs - $166.50 each
Redensity II PureSense departs from the RHA line but solves a problem those products were not built for: hollow, discolored under-eye skin. The formula blends cross-linked and non-crosslinked hyaluronic acid with eight amino acids and three antioxidants, including glutathione, to support skin quality rather than add pure volume.
Lidocaine keeps injections comfortable in one of the face’s most sensitive areas, and patients typically see results for 9 to 12 months. Practitioners pair it with RHA 4 or RHA 3 when a patient wants a fuller midface refresh in one visit.
Matching Each Teosyal Filler to a Treatment Zone
These best-selling Teosyal fillers cover distinct treatment zones, and matching the right product to the right area matters as much as picking a viscosity. Here is a quick reference for where each one performs best:
|
Filler |
Best Treatment Zone |
|---|---|
|
RHA 2 Lidocaine |
Perioral lines, early nasolabial folds, and other zones with fine-to-moderate movement |
|
RHA 3 Lidocaine |
Deeper nasolabial folds, marionette lines, and lip augmentation that needs more structure |
|
RHA 4 Lidocaine |
Cheek volume loss, jawline contouring, and midface sagging |
|
Teosyal RHA Kiss Lidocaine |
Lip volume and border definition, especially for first-time lip patients |
|
Redensity II PureSense |
Tear trough hollows and under-eye discoloration |
Stocking all five gives a practice full coverage from the upper cheek to the lip border without switching to a second filler brand mid-treatment.

How long do Teosyal fillers last?
Most RHA products last 12 to 15 months, with RHA 4 and RHA 3 on the longer end for deeper folds and volume loss. Redensity II PureSense typically lasts 9 to 12 months in the more delicate under-eye area.

Can Teosyal RHA fillers be combined in one treatment?
Yes, many practitioners combine RHA products in the same visit, such as RHA 4 in the cheeks with RHA 3 along the nasolabial folds. Because every RHA filler shares the same formulation technology, the gels behave consistently across treatment zones.
