    ObjectiveTo compare the safety and effectiveness of small particle hyaluronic acid plus lidocaine (SPHAL) versus no treatment for lip augmentation and perioral rhytides.Methods And MaterialsAdults scoring 1 (very thin) to 2 (thin) on the Medicis Lip Fullness Scale (MLFS) for upper and lower lips were randomized (3:1) to SPHAL or no treatment. Treatment success was an MLFS increase ≥1 point at Week 8. Secondary end points (MLFS score, independent photographic review, Global Aesthetic Improvement Scale, Wrinkle Assessment Scale for Upper Lip Lines) and safety were assessed throughout.ResultsStatistically significantly more patients were treatment successes with SPHAL (upper lip [80.2% vs 11.9%], lower lip [84.2% vs 18.4%], and upper and lower lips combined [76.1% vs 11.6%]), compared with no treatment (p <.001, all outcomes). Patients treated for both lip augmentation and perioral rhytides were rated as having an aesthetically meaningful improvement in perioral rhytides (p <.001). Most common treatment-emergent adverse events (AEs) included lip bruising, swelling, and pain and were mostly mild and transient in nature, without anticipated device AEs.ConclusionSmall 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.
