The Effect of Human Adipose Stem Cell-Conditioned Medium (hASC-CM) in Photoaged Skin

<b>Background:</b> Ultraviolet (UV) exposure causes direct and indirect damages to skin structures. Human adipose stem cell-conditioned medium (hASC-CM) is a collection of several soluble factors, such as cytokines, chemokines, and Growth Factors (GF), secreted by almost all living cells in the extracellular space which support wound healing and skin rejuvenation. <b>Objective:</b> To determine the effects of human adipose stem cell-conditioned medium (hASC-CM) in photoaged skin and evaluate photoaging improvement after treatment. <b>Methods:</b> An experimental randomized controlled trial was performed, involving 64 photoaged subjects at the Dermato-Venereology Outpatient Clinic of Jemursari Islamic Hospital Surabaya from March to June 2022. The subjects were divided into the hASC-CM group and vehiculum (control) group. Patients' transepidermal water loss value, skin tone, and Glogau score in weeks 0, 4, and 8 were evaluated. The data were then analyzed using Mann-Whitney test (p<0.05). <b>Results:</b> All subjects had Glogau scale of III (89.6%) with mean ± SD (3.121 ± 0.329). hASC-CM group showed higher improvements in the pore, wrinkle, spot polarized, spot UV parameters and skin tone compared to vehiculum group(p<0.05). <b>Conclusions:</b> hASC-CM effectively improved all parameters observed. The limitation of this research was on the lack of long-term follow-up after treatment. This research had received an ethical permit from The Ethical Committee Board of Jemursari Islamic Hospital Surabaya under letter 006/KEPK-RSISJS/II/2022.
