• Status: Not yet recruiting
• Conditions: Facial Wrinkles
• Intervention / Treatment: Procedure: Recombinant type III humanized collagen solution for injection; Other: SkinCeuticals recombinant humanized collagen (RHC) serum; Other: Regular face cream smear

Detailed Description

With the growth of photoaging and age, more people have the appearance of fine lines, skin laxity, roughness. Clinical evidences shown that RHC III injection can effectively improve fine line, skin plumpness and firmness to some extent; SkinCeutials RHC serum is capable of improving skin plumpness, firmness and elasticity, and improve rough skin condition.

A total of 54 subjects will be enrolled in this study, and half of the face of each subject will be randomly assigned 1:1 to the test side and the control side.

The subjects will receive one injection of recombinant type III humanized collagen solution and will be followed up for 12 weeks after injection treatment.

Experimental group: SkinCeuticals RHC cream and Regular cream (twice daily) Control group: Regular cream (twice daily)

Participants will be assessed by subjective questionnaire (FACE-Q Satisfaction with skin,Global Aesthetic Improvement Scale, et al) and some medical instruments (VISIA,Ultrascan UC22 et al)

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
FACE-Q Satisfaction with skin	FACE-Q is a recently developed and validated patient reported outcome measure (PROM) tool that allows clinicians to assess patient perspectives after medical aesthetic treatment in the face.The PROM is used to assess the satisfaction skin care as well as its treatment on the patient's quality of life (QoL). The FACE-Q utilizes five scales to measure the psychometric, QoL, patient experience, and cosmetic outcomes. Raw scores are transformed to a 0-100 scale with a higher score indicating a better satisfaction	4 weeks after injection

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Investigator Global Aesthetic Improvement Scale (I-GAIS) Rates	Investigator Global Aesthetic Improvement Scale (I-GAIS) is a 5-level scale ranging from "1" (very much improved) to "5" (very much worse) to determine the degree of improvement of the treated areas. the rates of I-GAIS was defined as the proportion of subjects with a GAIS score of 1-3.	Enrollment day, 2 weeks ±3 days after injection, 4 weeks ±5 days after injection, 8 weeks ±2 weeks after injection, and 12 weeks ±2 weeks after injection.
Subject Global Aesthetic Improvement Scale (S-GAIS) Rates	Subject Global Aesthetic Improvement Scale (S-GAIS) is a 5-level scale ranging from "1" (very much improved) to "5" (very much worse) to determine the degree of improvement of the treated areas. the rates of S-GAIS was defined as the proportion of subjects with a GAIS score of 1-3.	Enrollment day, 2 weeks ±3 days after injection, 4 weeks ±5 days after injection, 8 weeks ±2 weeks after injection, and 12 weeks ±2 weeks after injection.
Improvement rate assessed by Atlas	The investigator evaluated the improvement around the face using Atlas facial wrinkle atlas, a validated wrinkle scoring system, in which crow's feet were divided into 7 different grades, forehead wrinkles were divided into 9 grades, forehead fine lines were divided into 8 grades, and Yintang wrinkles were divided into 7 grades. A higher grade means more wrinkles.The improvement rate was defined as the proportion of subjects with at least 1 point reduction in the wrinkle rating in different regions.	Enrollment day, 2 weeks ±3 days after injection, 4 weeks ±5 days after injection, 8 weeks ±2 weeks after injection, and 12 weeks ±2 weeks after injection.
Change in Cutometer® dual Analysis Score	The Cutometer® dual will be used to assess changes in skin outcomes. Analysis will be conducted by a board-certified dermatologist at baseline and follow up. Evaluated skin properties/parameters included skin moisture content, transepidermal water loss, skin elasticity, and skin tightness. Collection of these parameters will be performed using a probe dedicated to the Cutometer®dual. The results are then used to generate a comprehensive analysis report, which includes both the quantitative measurements and qualitative assessments, along with any corresponding scores or ratings assigned to different skin attributes.	Enrollment day, 2 weeks ±3 days after injection, 4 weeks ±5 days after injection, 8 weeks ±2 weeks after injection, and 12 weeks ±2 weeks after injection.
Change in VISIA® Skin Analysis Score	VISIA® Skin Analysis system will be used to assess changes in skin outcomes. Analysis will be conducted by a board-certified dermatologist at Baseline and follow up. The VISIA® Skin Analysis system will be used to capture the images which will then be processed by the VISIA software.The software utilizes advanced algorithms to detect and measure specific skin attributes. The skin attributes/parameters evaluated will be spots, pores, wrinkles, texture (roughness and smoothness of the skin), purple patches of the dermal layer, brown patches of the dermal layer, red areas and porphyrins. These parameters are evaluated using the captured images and the specialized algorithms employed by the VISIA software. The results are then used to generate a comprehensive analysis report, which includes both the quantitative measurements and qualitative assessments, along with any corresponding scores or ratings assigned to different skin attributes.	Enrollment day, 2 weeks ±3 days after injection, 4 weeks ±5 days after injection, 8 weeks ±2 weeks after injection, and 12 weeks ±2 weeks after injection.
FACE-Q Satisfaction with Outcome	FACE-Q is a recently developed and validated patient reported outcome measure (PROM) tool that allows clinicians to assess patient perspectives after medical aesthetic treatment in the face.The PROM is used to assess the perspective and impact of skin care as well as its treatment on the patient's quality of life (QoL). The FACE-Q utilizes five scales to measure the psychometric, QoL, patient experience, and cosmetic outcomes. Raw scores are transformed to a 0-100 scale with a higher score indicating a better outcome	Enrollment day, 2 weeks ±3 days after injection, 4 weeks ±5 days after injection, 8 weeks ±2 weeks after injection, and 12 weeks ±2 weeks after injection.
