Advancing industry standards through scientific precision and intentional innovation

Preserved Network Technology (PNT)

A revolutionary hyaluronic acid (HA) manufacturing process that sets the standard for dynamic HA fillers1-3

PNT is the first and only heatless, homogenous manufacturing process in gentle conditions that helps preserve the natural structure of hyaluronic acid, producing Resilient Hyaluronic Acid (RHA®) gels.1,2

Traditional fillers - HA structure

Traditional fillers1,4

  • Created in harsh conditions
  • Higher degree of modification/ crosslinking
  • Shorter, more fragmented HA chains
Natural HA structure

Natural HA5-7

  • Long, unmodified HA chains
  • Possess viscoelastic properties and provide volumization
RHA structure

RHA®1,4

  • Low degree of modification, closely resembling HA found in skin
  • Designed to preserve long HA chains from fragmentation in the manufacturing process
  • Move with the face's natural expressions

The importance of dynamic strength and stretch

Over 20 years of innovation8

For over two decades, Teoxane Laboratories has been at the forefront of hyaluronic acid innovation, setting the standard for what a filler should be.

Teoxane Laboratories Founded

Madame Valerie Taupin founds Teoxane Laboratories in Geneva, Switzerland, in 2003.8

Teoxane Launches First Products

In 2006, Teoxane launches their first pioneering products in Europe.8

PNT Revolutionizes Filler Manufacturing

Preserved Network Technology (PNT) is the first and only gentle, heatless manufacturing process for facial fillers designed for natural looking outcomes.1,2

Teoxane RHA® Collection Launches Globally

In 2015, Teoxane launches the RHA® Collection in Europe with their first line of facial fillers designed to adapt to facial movement.1,8

Teoxane RHA® Collection comes to the U.S.

Always at the forefront of global innovation, the Teoxane RHA® Collection launches in the U.S. in 2020.8

The Teoxane® RHA Collection with Mepivacaine*

The first major innovation in hyaluronic acid filler anesthetic in the U.S. in almost 20 years9

*Patented technology

The same high-quality, signature results and efficacy you expect with RHA®

  • Same rheology10
  • Similar pain control†11
  • Established safety profile11
  • No change in aesthetic outcomes11

Mepivacaine has been found to have less vasodilation than lidocaine.12-14

  • Reduced vasodilation may be associated with a lower potential for bleeding and bruising14-15

The primary endpoint was the injection site pain felt during the injection, as assessed by the subject on a 100-mm VAS, immediately after injection in each upper perioral quadrant (RHA Redensity® mepivacaine study) or each NLF (RHA® Dynamic Volume mepivacaine study).

The Teoxane RHA® Collection includes hyaluronic acid (HA) fillers with lidocaine and mepivacaine. Revance will only distribute the Teoxane RHA® Collection with mepivacaine, thus may refer to the products without the use of "Mepi" in the product name. The long-term efficacy and safety outcomes of RHA® with lidocaine are applicable to RHA® with mepivacaine, and mepivacaine has shown no significant impact on gel properties, including rheology and degradation profile.

RHA® Collection of Fillers, by Teoxane

Indications

The Teoxane RHA® Collection of resilient hyaluronic acid (HA) fillers includes RHA Redensity®, RHA® 2, RHA® 3 and RHA® 4 with lidocaine and RHA Redensity® Mepi, RHA® 2 Mepi, RHA® 3 Mepi and RHA® Dynamic Volume, with mepivacaine.

RHA Redensity® and RHA Redensity® Mepi are indicated for injection into the dermis and superficial dermis of the face, for the correction of moderate to severe dynamic perioral rhytids in adults 22 or older. RHA® 2 and RHA® 2 Mepi are indicated for injection into the mid-to-deep dermis for the correction of moderate to severe dynamic facial wrinkles and folds, such as nasolabial folds (NLFs) in adults 22 or older. RHA® 3 and RHA® 3 Mepi are indicated for injection into the mid-to-deep dermis for the correction of moderate to severe dynamic facial wrinkles and folds, such as nasolabial folds (NLFs) and is also indicated for injection into the vermillion body, vermillion border and oral commissure to achieve lip augmentation and lip fullness in adults 22 or older. RHA® 4 is indicated for injection in the deep dermis to superficial subcutaneous tissue for the correction of moderate to severe dynamic facial wrinkles and folds, such as nasolabial folds (NLFs) in adults 22 or older. RHA® Dynamic Volume is indicated for injection in the deep dermis to superficial subcutaneous tissue for the correction of moderate to severe dynamic facial wrinkles and folds, such as nasolabial folds (NLFs) and for injection into the subcutaneous to supraperiosteal layers for cheek augmentation and/or correction of age-related midface contour deficiencies in adults 22 or older.


IMPORTANT SAFETY INFORMATION

Contraindications

Do not use in patients who have severe allergies, marked by a history of anaphylaxis or multiple severe allergies, or in patients with a history of allergies to gram-positive bacterial proteins or local anesthetics of the amide type, such as lidocaine and mepivacaine.

Do not use in patients with bleeding disorders.

Warnings

Do not inject into blood vessels. Introduction of these products into the vasculature may lead to embolization, occlusion of the vessels, ischemia, or infarction. Take extra care when injecting soft-tissue fillers; for example, inject the product slowly and apply the least amount of pressure necessary. Rare, but serious, adverse events associated with the intravascular injection of soft-tissue fillers in the face have been reported and include temporary or permanent vision impairment, blindness, cerebral ischemia or cerebral hemorrhage leading to stroke, skin necrosis, and damage to underlying facial structures.

Immediately stop the injection if a patient exhibits any of the following symptoms: changes in vision, signs of a stroke, blanching of the skin, or unusual pain during or shortly after the procedure. Patients should receive prompt medical attention and, possibly, evaluation by an appropriate healthcare professional specialist should an intravascular injection occur.

Product use at specific sites in which an active inflammatory process or infection is present should be deferred until the underlying process has been controlled.

Precautions

These products should only be used by healthcare professionals who have appropriate training, experience, and knowledge of facial anatomy.

Discuss the potential risks of soft-tissue injections with your patients prior to treatment and ensure that patients are aware of signs and symptoms of potential complications.

The safety and effectiveness for the treatment of anatomic regions other than the labeled indications have not been established in controlled U.S. clinical studies
As with all transcutaneous procedures, dermal filler implantation carries a risk of infection. Standard precautions associated with injectable materials should be followed.

The safety for use in sites in the presence of other implants, during pregnancy, in breastfeeding females, and in patients with known susceptibility to keloid formation, hypertrophic scarring, and pigmentation disorders has not been studied.
Use with caution in patients on immunosuppressive therapy.

Patients who are using products that can prolong bleeding (such as thrombolytics, anticoagulants, or inhibitors of platelet aggregation) may experience increased bruising or bleeding at treatment sites.

Patients with a history of herpetic eruptions may experience reactivation of the herpes.

There is a possible risk of inflammation at the implant site if laser treatments or a chemical peel are performed after treatment.

Use as supplied. Modification or use of the product outside the Directions for Use may adversely impact the sterility, safety, homogeneity, or performance of the product.

For single patient use. Do not reuse a syringe between two treatments and/or between two patients. Do not resterilize.

Adverse Events

The most commonly reported side effects were firmness, redness, tenderness, swelling, lumps/bumps, bruising, discoloration, pain and itching. Most of these events were mild or moderate and resolved within 14 days.

Delayed-onset inflammation near the site of dermal filler injections is one of the known adverse events associated with dermal fillers. Cases of delayed-onset inflammation have been reported to occur at the dermal filler treatment site following viral or bacterial illnesses or infections, vaccinations, or dental procedures. Typically, the reported inflammation was responsive to treatment or resolved on its own.
