Swift A, et al. – This study incorporated the estimation of minimal recovery time needed to return to social engagement (RtSE )following nasolabial fold (NLF) correction with hyaluronic acid fillers produced with XpresHAn technology. It was determined that the optimal correction of moderate NLFs with R_R (Restylane Refyne) and severe NLFs with R_D (Restylane Defyne) involved minimal time to RtSE for a majority of the candidates. It was noted that the treatments that considerably improved Wrinkle Severity Rating Scale (WSRS) and Global Aesthetic Improvement Scale (GAIS), were generally well–tolerated, and provided natural–looking aesthetic outcomes.
