What it is
Human Stem Cell Conditioned Media is the liquid in which human stem cells have been grown, collected after the cells are removed. It contains the soluble factors the cells secreted into the medium and is used in cosmetics as a skin-conditioning ingredient. It does not contain live cells.
Safety & warnings
As a biotechnology-derived material from human cells, its acceptance and regulatory status differ across markets and warrant attention. Cosmetic tolerability data is more limited than for conventional ingredients.
Origin & sourcing
Biotechnologically produced; the spent culture medium recovered from laboratory-grown human stem cells, filtered to remove the cells.
