Study Overview
Brief Summary
To evaluate the efficacy and safety of recombinant humanized collagen (type III) solution for injection combined with SkinCeuticals recombinant humanized collagen (RHC) serum 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)
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 Prospective, single-center, randomized, split-face controlled, single-blind evaluation, superior efficacy clinical trial to evaluate the efficacy and safety of recombinant humanized collagen (type III) solution for injection combined with SkinCeuticals recombinant humanized collagen (RHC) serum, to explore the synergetic effects of injectable integrated skincare in Chinese population.
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)

Outcomes
Primary Outcomes
FACE-Q Satisfaction with skin
Time Frame: 4 weeks after injection
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
