Our scientists make use of these in vitro (test tube) human skin systems in conjunction with the latest proteomic techniques to maximize data value while keeping costs to a minimum. The scope of an experiment can encompass a range of experimental complexities from simple screening assays costing a few hundred dollars to complex comparative assays involving the application of numerous techniques including multiplex immuno-assays, mass spectrometry, histology, gene expression analysis etc.
The development of skin care treatments has been traditionally hampered by the lack of good models for human skin. Skin removed from cadavers, animals and transformed cultured cells have traditionally been used as surrogates to study the effects of various skin treatments. 
Fortunately, advances in tissue culture techniques have finally made available a number of fully human skin models having the structural and functional components of intact human skin.
The introduction of bead based multiplex immunoassay techniques has allowed these systems to be used to their fullest potential in conducting studies of drug effects on skin.
Other available tissues include ocular, oral, vaginal and lung tissues.
