About the study
“The Effect of Multisyringe Hyaluronic Acid Facial Rejuvenation on Perceived Age” was published in Dermatologic Surgery (Dermatol Surg 2010; 36: 323–328). In the study, three blinded board-certified cosmetic dermatologists rated 36 images taken by the VISIA CR system, all of the images were of the lower two-thirds of the face (the upper third was not treated) and included a standardized frontal view and two side views at 45° angles.
The images were scrambled such that there was no indication of which photos were before and after. Each clinical investigator was instructed to look at each image and spend no more than 30 seconds rating the subject’s age. They were also instructed not to compare photos or change any age rating after 30 seconds.
Analysis of the data revealed that multisyringe injection of hyaluronic acid filler into the aging face results in a reduction of apparent age of 6.1 to 9 years younger after two to four weeks.
