Cosmetic preparations are thought to support and help the vitality of the skin.
An acknowledged method to determine the vitality of tissues is the MTT Viability Test.For the MTT-Test, living cells are inserted in a 96 well plate and treated with the cosmetic formulation in question. Then, MTT (a yellowish salt) is added, which is changed in color only by living cells into the purple Formazan.
The intensity of color change can be determined with photometric measurements, and because the intensity of color is directly connected to the amount of living cells, it can then be concluded how many cells were  damaged by direct contact to the cosmetic preparation.
