Because satisfactory initial correction can be obtained with all these agents, duration of cosmetic correction is an important distinguishing characteristic.
OBJECTIVE The objective was to compare the efficacy and duration of treatment effects of HA gel and hylan B plus gel for the cosmetic correction of nasolabial folds.
METHODS Fifteen patients with prominent nasolabial folds were randomized to treatment with HA gel and hylan B plus gel on contralateral sides of the face. Wrinkle severity and global aesthetic improvement were assessed by patients and a blinded evaluating investigator. Wrinkle Severity Rating Scale scores and Global Aesthetic Improvement Scale scores on both facial sides were assessed 2 weeks, 3 months, 4.5 months, and 6 months after treatment.
RESULTS Wrinkle Severity Rating Scale scores and Global Aesthetic Improvement Scale scores were significantly higher for HA gel at 3, 4.5, and 6 months as assessed by both patients and evaluating investigator.
CONCLUSION Both HA gel and hylan B plus gel provide dermal augmentation of nasolabial folds. The magnitude and duration of nasolabial fold correction appear to be greater for the HA gel than for the hylan B plus gel. | | Language | eng | | Pub Type(s) | Journal Article
