3 Fig 2 Improvement in Wrinkle Assessment Scale (WAS) score, as shown by mean (standard error [SE]) change from baseline by visit. Scale of figure has been reversed to show positive improvement, correlating with decreasing WAS values from baseline. Week 3 (W3) is first follow-up time point after final treatment session. Subjects received between one and 4 treatments every 3 weeks until optimum correction. M, Month. ∗P < .001 vs baseline; †P < .001 vs human collagen; ‡only subjects treated with injectable poly-L-lactic acid (PLLA) (n = 106) were included in long-term surveillance phase.
