Development of Products Based on Secretom From Stem Cell Conditioned Medium for Melasma Therapy

The secretome used in this research comes from mesenchymal stem cells from adipose tissue produced by IPT RSCM Stem Cell Medical Technology. The secretome produced by mesenchymal stem cells is collected, centrifuged to separate it from debris, and followed by filtration with a 0.22 μm pore filter to ensure sterility. Next, the concentration process is carried out using tangential flow filtration with the Spin-X UF 500® concentrator, packaged, and stored at -80 degrees Celsius. The product used is a sterile product, which is tested for sterility and total protein content. When it is to be used, the secretome is removed from the freezer, warmed (thawing), and injected into the patient according to a predetermined method.
