abstract = {The stratum corneum (SC) is the largest physical barrier of
the human body. It protects against physical, chemicaland
biological damages, and avoids evaporation of water from the
deepest skin layers. For its correct functioning,the
homeostasis of the SC lipid matrix is fundamental. An
alteration of the lipid matrix composition and inparticular
of its ceramide (CER) fraction can lead to the development
of pathologies such as atopic dermatitis andpsoriasis.
Different studies showed that the direct replenishment of SC
lipids on damaged skin had positive effectson the recovery
of its barrier properties.In this work, cerosomes, i.e.
liposomes composed of SC lipids, have been successfully
prepared in order toinvestigate the mechanism of interaction
with a model SC lipid matrix. The cerosomes contain CER[NP],
D-CER[AP], stearic acid and cholesterol. In addition,
hydrogenated soybean phospholipids have been added to one
ofthe formulations leading to an increased stability at
neutral pH. For the mode of action studies, monolayermodels
at the air-water interface and on solid support have been
deployed. The results indicated that a stronginteraction
occurred between SC monolayers and the cerosomes. Since both
systems were negatively charged, thedriving force for the
interaction must be based on the ability of CERs head groups
to establish intermolecularhydrogen bonding networks that
energetically prevailed against the electrostatic repulsion.
This work proved forthe first time the mode of action by
which cerosomes exploit their function as skin barrier
repairing agents on theSC.},
