Abstract (original English)

Background: 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. Objective: To determine the effects of human adipose stem cell-conditioned medium (hASC-CM) in photoaged skin and evaluate photoaging improvement after treatment. Methods: 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). Results: 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). Conclusions: 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 a
