Abstract

Clinicians employ several techniques to augment lips with hyaluronic acid (HA) filler. To the best of our knowledge, however, no previous study has documented the use of a 4-mm 30-gauge needle in this context. This paper describes the anatomical rationale behind and practical application of such a needle applied very superficially in the vermillion border during lip augmentation. Using a 4-mm 30-gauge needle facilitates precise HA placement into the safer subcutaneous plane of the lip and lowers the pressure needed to extrude the filler, which might optimize patient comfort. This technique aims to increase the safety and predictability of lip augmentation with HA fillers. Credit is owed to Dr. Jean Louis Sebagh, who provided the inspiration to use the described needle for this evidence-based technique.
