Beyond the human body, serum is a workhorse in laboratories worldwide. Fetal Bovine Serum (FBS) is the most common supplement added to cell culture media. It provides a complex cocktail of growth factors, hormones, and attachment factors that are necessary for most human and animal cells to grow and divide outside the body. Without FBS, the production of many modern biologics would be impossible. This includes the manufacturing of monoclonal antibodies (used for cancer and autoimmune diseases), viral vectors for gene therapy, and the cell lines used to produce vaccines (including the COVID-19 vaccines from Novavax and many influenza vaccines).
To understand why a is non-negotiable in a serious skincare routine, one must understand the concept of bioavailability.
Serums are generally water-based, though oil-based serums exist for drier skin types. They forego the heavy "filler" ingredients found in creams (like petroleum or mineral oil) and instead focus on a vehicle that transports potent ingredients like antioxidants, peptides, and vitamins where they are needed most.
