Skin Inflammation, Stem Cell Transplant Complications
Conditions
Brief summary
The aim of this study is the safety and efficacy of autologous very small embryonic-like stem cells(VSELs) to facial skin antiaging.
Detailed description
VSELs come from the patient's peripheral blood, and will be injected in left preauricular area, followed by skin pathology to compare the improvement of skin aging. Two 0.5 × 1 cm fragments of skin and subcutaneous tissue was removed from bilateral preauricular areas for morphologic analysis by optical and electron microscopy. Histologic analysis of skin biopsy specimens was performed by hematoxylin and eosin, picrosirius red (for visualization of collagen), and orcein (for visualization of elastic fibers) staining.
Interventions
We carried out the subdermal application of VSELs with a 1-mL syringe (volume, 0.4 mL) coupled to a 30-gauge needle, in the left preauricular area (1-cm2 area), 2 cm distal from the tragus

Study design
Masking description
The volunteers will be randomly arranged to enter the experimental group or the control group.
Intervention model description
In the experimental group, VSELs will be injected in left preauricular area of every volunteer, followed by skin pathology to compare the improvement of skin aging with the skin of right preauricular area. In the control group, platelet-rich plasma will be injected to the left preauricular area of every volunteer.
