in vitro efficacy testing of finished products?
I have been thinking about this question for some time. I am not a (cosmetic) chemist, just a biologist and new in this field. I want to do in vitro efficacy testing of some finished skincare products (serum, emulsion, cream etc.) by using biochemical (antioxidant etc.) and cell-based (cell viability, ROS etc.) approaches. However, I realised that the final product would be diluted during the experiment, so the outcome may not reflect the real effect. The other issue is that those finished products sometimes do not completely dissolve (maybe because of emulsifiers etc.) and interfere with the assay ending up with non-consistent and irrelevant outcome or the assay doesn’t work at all. I wonder how finished products can be in vitro tested for efficacy? Is there any resources like guidelines, books, articles etc.?If you guide me, I will highly appreciate. Thanks</font>
