421 INVESTIGATIVE REPORT Degree of Skin Barrier Disruption Affects Lipid Organization in Regenerated Stratum Corneum Tineke BERKERS, Dani VISSCHER, Gert S. GOORIS and Joke A. BOUWSTRA Department of Drug Delivery Technology, Cluster BioTherapeutics, Leiden Academic Centre for Drug Research, Leiden University, Leiden, The Netherlands Previously, a skin barrier repair model was developed to examine the effect of formulations on the lipid pro- perties of compromised skin. In this model, the lipid organization mimics that of several skin diseases with impaired skin barrier and less dense lateral lipid orga- nization. In addition, parakeratosis was occasionally observed. The present study investigated whether the extent of initial barrier disruption affects lipid orga
