Conditioned media in cosmetics is a form of cell culture media that has been exposed to stem cells and contains cell-derived factors such as proteins and hormones. It is used in the production of cosmetics to provide essential nutrients for skin health and rejuvenation. This type of media is beneficial in cosmetics because it can help boost cell growth and health, reduce redness, and improve the tone and texture of the skin. Conditioned media can also be used to supplement the cosmetics with additional factors such as growth factors and hormones, or to replace certain components such as serum or antibiotics.
