Liquid Surgery Complex is a synthetic oxygen carrier (no active, concentrated oxygen) with perfluorodecalin's main complex. It is the strongest gas carrier known to date and is used in medicine as a hemoglobin replacement. For the skin, however, the compound with the excess carbon dioxide is even more important. CO2 is immediately absorbed after application from low oxygen partial pressure areas, and the cell metabolism is refreshed. Carbon dioxide replaces the natural oxygen from the ambient air and the blood. Improving the oxygen supply can counteract skin aging and result in an astounding smoothing of the skin.
