Bertucci V, Nikolis A, Solish N, et al. - Researchers conducted the study for assessing subject and partner satisfaction with the hyaluronic acid (HA) dermal filler HA_RK for lip enhancement at 8 weeks after the last treatment. In this open‐label study, participants 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). Nineteen individuals received HA_RK only; 40 also received HA_RR and/or HA_RD. This investigation showed that HA_RK, whether used alone or in combination with HA_RR/HA_RD in NLFs and MLs, resulted in lip enhancement with high levels of subject and partner satisfaction.
