Perioral rejuvenation with a range of customized hyaluronic acid fillers: efficacy and safety over six months with a specific focus on the lips.

BACKGROUND

Injectable fillers are frequently used to restore volume and correct wrinkles in perioral region. However, evidence for perioral indications is scarce.

OBJECTIVE

Assess the efficacy, patient satisfaction, and safety of new range of hyaluronic acid fillers (HA E) in perioral enhancement.

MATERIALS AND METHODS

This was a multi-center, six-month, open-label study. At baseline, subjects could receive HA E Touch, HA E Classic, HA E Lips and HA E Deep for the treatments of lips, upper lip lines, nasolabial folds and marionette lines, and a touch-up infection was optional three weeks later. Lip Fullness Grading scale (for lips), wrinkle assessments (Lemperle Rating Scales for the remaining indications), adverse events, and local tolerance were evaluated at each visit, and 3-D volume analyses (for nasolabial folds and lips only) at each post-baseline visit. Optimal correction was defined as results obtained three weeks after last injection. A subject satisfaction questionnaire was performed three weeks after last infection.

RESULTS

Overall, HA E Lips was infected for lip enhancement, HA E Thouch and HA E Classic for upper lip lines, and HA E Classic and HA E Deep for both nasolabial folds and marionette lines. After six month, around a 1-grade improvement persisted according to the lip fullness and wrinkle assessment scales. The long duration of effect was confirmed by 3-D analyses, with 62.7-71.4 percent of volumes obtained at week 3 (optimal correction) maintained after six months. The majority of subjects (from 80% for upper lip lines with HA E Classic to 94.8% for nasolabial folds with HA E Deep) were satisfied or very satisfied with their aesthetic outcome. All products were safe and well-tolerated.

CONCLUSIONS

Perioral enhancement with HA E fillers led to sustained effect in terms of lip fullness, wrinkle and 3-D volume assessments, and high subject satisfaction.
