Small gel particle hyaluronic acid injection technique for lip augmentation.

Optimizing the aesthetic outcome of lip augmentation with dermal fillers, such as small gel particle hyaluronic acid (SGP-HA), requires skillful application of a suitable injection technique. Moreover, achieving aesthetic goals with minimal risk for adverse events requires knowledge of lip anatomy and function, clinical experience in the use of various injection techniques, and an individualized treatment approach. Clinician-patient discussion of the initial assessment of lip presentation and global appearance of lip shape and proportion is important in setting treatment expectations and establishing a basis for follow-up assessment of the effectiveness of treatment. The effectiveness and safety of SGP-HA for lip augmentation was demonstrated in a recent randomized controlled trial. This review discusses factors influencing the choice of one or a combination of techniques for injection of SGP-HA for aesthetic lip augmentation.
