*Longevity owes to a variety of factors, which include clinical trials study design, methodology, amount of filler injected, and treatment area. When comparing patient-to-patient variability, other factors such as the patient's metabolism and soft-tissue matrix need to be considered.
**Restylane was shown to maintain correction at 18 months following repeat injection at 4.5 months. This study led to a second submission to the FDA, known as a supplemental Premarket Approval Application for its label, giving a new indication for Restylane—longevity up to 18 months with repeat injection at 4.5 months.

***G’ (pronounced G prime), quantified in pascals, is the elastic modulus or measure of gel stiffness, increases with degree of crosslinking, and estimates resistance to deformation. Examples: high elasticity= rubber band; low elasticity=syrup. The higher the G’ the more firm the product. The ability of a filler to lift soft tissue is directly related to the G prime, but also directly related to cohesivity. Increasing the cohesivity and decreasing the G prime is a fundamental feature of softer, homogenized HAs compared to particle-based (e.g., calcium hydroxylapatite), fillers which rely on a higher G prime to create lift. Even within the HA products, the Restylane filler family relies on a high G prime with its uniform particle size to achieve lift, while the Juvéderm family relies on higher cohesivity.
BDDE stands for 1,4-butanediol diglycidyl ether. The majority of hyaluronic fillers are crosslinked with BDDE.
Juvéderm Voluma (HA, Galderma) is another example of a filler that achieves a significant lift by employing high cohesivity, but a lower G prime compared to the Restylane Lyft. Both are FDA-approved as robust fillers for the mid-face.
All fillers listed above are available in 1ml syringe sizes, exceptforJuvéderm Volbella, which comes in a 0.55ml syringe. All exceptfor Belotero Balance are available with 0.3% Lidocaine. It is notable that Revanesse Versa (sans “Plus”) is available without lidocaine. It was omitted from the table for simplification.
NASHA= Trademark of Q-Med (owned by Galderma) stands for Non-Animal, Stabilized Hyaluronic Acid.
xPresHAn= Trademark of Galderma. XpresHAn Technology customizes the degree of hyaluronic acid (HA) crosslinking in each product, resulting in gels with a range of flexibility and support characteristics for different patient needs. The “x” stands for “cross-linking.” “Pres,” because gels are pressed through a mesh for calibration. “HA” stands for Hyaluronic Acid. The “n” was simply added to the end to make it sound more like a familiar word. G’ (elastic modulus) values were obtained from JDD: January 2012, Volume 11, Issue 1 (SUPPLEMENT) with respect to Emervel Classic, Lips, and Deep. Touch and Volume versions are not available in the US as of 6-2020
Hylacross= Trademark of Allergan. “Hyla-“ derives from “Hyaluronic Acid.” “Cross” implies “cross-linking.”
Vycross = Trademark of Allergan. Uses a combination of low and high molecular weight HA to improve the cross-linking efficiency of HA chains. Vollure® is known as Volift ® in countries outside the United States.
CPM= Trademark of Merz. Cohesive Polydensified Matrix
