How to choose the right HA filler

Choosing the right hyaluronic acid filler is one of the most consequential decisions an aesthetic physician makes during consultation planning. Product selection accounts for roughly 70% of the natural, durable, complication-free result — technique drives the remaining 30%. This guide outlines the practical criteria that help clinics pick the right product for the right indication and the right patient.

Understanding density (G' and concentration)

Elastic modulus G' measures the firmness of the gel. The higher the G', the more the filler resists deformation. For deep folds (nasolabial, marionette lines), a G' above 400 Pa is generally recommended. Conversely, for the perioral or periocular area, a G' below 200 Pa yields a more natural finish and limits the "mass" effect.

Matching the filler to the area

• Cheeks & malar : high G' (>500 Pa), 20-25 mg/mL — deep volumizers like Voluma, Restylane Lyft, Belotero Volume.
• Nasolabial folds : medium G' (250-400 Pa) — Restylane Refyne, Juvéderm Vollure, Teosyal Ultra Deep.
• Lips : low G' (100-250 Pa), high cohesivity — Volbella, Restylane Kysse, Teosyal Kiss.
• Tear-trough : low G', low hydrophilicity to avoid Tyndall — Restylane Vital, Teosyal Redensity II.

Summary

HA filler selection is not an isolated act — it is part of a long-term treatment strategy. Documenting products used, batch numbers and clinical evolution lets the clinic build a precise internal reference.
