Skin: target or barrier - conference papers

This item first appeared in 2007

London, 1 November 2007

The human skin has a dual function as a barrier to unwanted substances, but also as a delivery route for therapeutic chemicals. Both areas of science use similar technologies and techniques to assess the passage and influence of chemicals crossing the skin. Skin – target or barrier, a one day meeting, aimed to bring together scientists interested in the problems relating to the transfer of xenobiotics into and across the skin. The programme focused on understanding both the promotion and the retardation of dermal penetration.

State of the art biophysical techniques for characterisation of permeant transport across membranes were presented, with a particular emphasis on spectroscopic approaches to interrogate the skin. Formulation strategies for pharmaceuticals and cosmeceuticals was reviewed. The development and application of models to predict skin toxicity was addressed. The sourcing of data for toxicology quantitative structure-activity relationships (QSAR) was discussed as well as the development and application of models for human health effects and the implications of the REACH initiative for the scientific and industrial community.

The programme included presentations from internationally recognised leaders in the fields of skin permeation and dermal risk assessment.
