Randomized Controlled Trial
A randomized, evaluator-blinded, controlled study of effectiveness and safety of small particle hyaluronic acid plus lidocaine for lip augmentation and perioral rhytides.
To compare the safety and effectiveness of small particle hyaluronic acid plus lidocaine (SPHAL) versus no treatment for lip augmentation and perioral rhytides. ⋯ Small particle hyaluronic acid plus lidocaine was effective and well tolerated and significantly more effective when both lips and perioral rhytides were treated, with improvement evident up to 6 months after treatment.

Randomized Controlled Trial
Functional safety assessments used in a randomized controlled study of small gel particle hyaluronic acid for lip augmentation.
Dermal fillers are commonly injected in the lips for aesthetic treatment. Small gel particle hyaluronic acid (SGP-HA) is the only filler approved by the US Food and Drug Administration for this indication, based on a pivotal trial of effectiveness and safety. ⋯ Lip augmentation with SGP-HA showed excellent safety with the assessments used in this study. Further study should be conducted to validate these assessments with the goal of developing a comprehensive scale for measuring potential functional complications and risks.
