Subject and partner satisfaction with lip and perioral enhancement using flexible hyaluronic acid fillers

The injection of hyaluronic acid (HA) dermal fillers is a popular minimally invasive approach to improve lip volume and contour, and with improved techniques has gained popularity because full lips are often associated with beauty and youth. Patient satisfaction is a key driver for successful aesthetic procedures, influencing individual treatment plans and future recommendations.

To evaluate subject and partner satisfaction with the hyaluronic acid (HA) dermal filler HA_RK for lip enhancement at 8 weeks after the last treatment.

Subjects in this open-label study all received HA_RK in the lips, and an additional group also received HA_RR and/or HA_RD in nasolabial folds (NLFs) and marionette lines (MLs). Satisfaction was assessed at Weeks 4 and 8 after the last treatment using questionnaires (FACE-Q™ [subjects] and KISSABILITY [subjects and partners]).

Nineteen subjects received HA_RK only; 40 also received HA_RR and/or HA_RD . Subjects reported a high level of satisfaction with their lips following treatment. Increases from baseline in the mean total satisfaction score were statistically significant at Weeks 4 and 8 (P ≤ .001). Most subjects (≥89%) reported satisfaction on all FACE-Q questions at Week 8. Both subjects and partners were satisfied with the kissability, appearance, and natural look and feel of the post-treatment results.

This study demonstrated that HA_RK resulted in lip enhancement with high levels of subject and partner satisfaction, when used alone or in combination with HA_RR / HA_RD in NLFs and MLs.
