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)

Full description
