Hyaluronic acid (HA) soft tissue fillers are popular for volumizing, sculpting, or rejuvenating the face. Their effect beyond these cosmetic benefits remains poorly defined, especially the changes in the psychological and social dimensions of health following cosmetic HA filler injections. To determine whether injecting more facial aesthetic units with HA soft tissue filler will improve the health-related quality of life dimension of patients. A prospective study was conducted to assess the psychological and social benefits of treating multiple facial aesthetic units with HA soft tissue filler using 3 validated FACE-Q scales at baseline and 4 weeks posttreatment between January and August 2022. Data for 28 participants (n = 26 females [93%]; mean age: 49.7 ± 10.1 years) are available and reveal significant improvements on the psychological (+24.5; P < .001) and social functioning (+18.5; P < .001) FACE-Q scales and a reduction in the appearance-related distress score (-17.8; P < .001) posttreatment compared to baseline. A mean volume of 4.7 mL (range 1.0-15.2 mL) was injected. However, patients who had >2 facial aesthetic units injected did not statistically score better on the FACE-Q scales. Facial treatment with HA fillers was associated with a marked improvement in the health-related quality of life dimension. While understanding patients' aims and motivation, an individualized treatment approach is strongly encouraged instead of a "whole-face" approach.
