In order to assess the regenerative activity of a given cosmetic product on cell cultures of human keratinocytes, an MTT test and an analysis of overall protein synthesis are performed. The MTT test, in addition to evaluating the viability of in vitro cells exposed to different concentrations of the product in comparison to untreated cells, also makes it possible to determine the concentration, if any, that is capable of stimulating cell growth. Protein synthesis is also evaluated in order to establish whether the product/raw material has regenerative activity.
Execution time: 40 (forty) business days from the arrival of the product at our facility.
