Primary Outcome Measures

Name	Time	Method
Change in WSRS(Wrinkle Severity Rating Scale) score by independent evaluators from Baseline to Week 24.	Baseline and Week 24	Independent evaluators evaluate the WSRS score change at Week 24 compared to baseline.

Secondary Outcome Measures

Name	Time	Method
Change in Wrinkle Severity Rating Scale(WSRS) score by independent evaluators from Baseline to Weeks 8, 16 and 48.	Baseline and Weeks 8, 16 and 48.	WSRS(Wrinkle Severity Rating Scale) grading scale from 1 to 5, with grade 1 as absent, grade 2 as mild, grade 3 as moderate, grade 4 as severe, grade 5 as extreme.
Success rate of treatment(N%) by independent evaluators from Baseline to Weeks 8, 16, 24 and 48.	Baseline and Weeks 8, 16, 24 and 48.	The percentage of subjects whose WSRS score was lowered by 1 or more points.
Change in Wrinkle Severity Rating Scale(WSRS) score by investigator from Baseline to Weeks 8, 16, 24 and 48.	Baseline and Weeks 8, 16, 24 and 48.	WSRS(Wrinkle Severity Rating Scale) grading scale from 1 to 5, with grade 1 as absent, grade 2 as mild, grade 3 as moderate, grade 4 as severe, grade 5 as extreme.
Success rate of treatment(N%) by investigator from Baseline to Weeks 8, 16, 24 and 48.	Baseline and Weeks 8, 16, 24 and 48.	The percentage of subjects whose WSRS score was lowered by 1 or more points.
Global Aesthetic Improvement Scale (GAIS) from Baseline to Weeks 8, 16, 24 and 48.	Baseline and Weeks 8, 16, 24 and 48.	Global Aesthetic Improvement Scale (GAIS) from -1 to 3, with grade -1 as worse, grade 0 as no change, grade 1 as improved, grade 2 as much improved, grade 3 as very much improved.
Visual Analog Scale (VAS) after the treatment.	Baseline	Visual Analog Scale (VAS) from 0mm to 100mm, with 0mm as no pain, 100mm as maximum pain.
