Abstract: Compositions, kits and methods are provided for restoring skin barrier function to skin exposed to environmental elements and/or in a pathological condition. In general, divalent cations such as calcium ions and/or magnesium ions are included in a physiologically acceptable medium. In some embodiments, divalent cations are balanced with monovalent cations such as sodium and potassium ions at appropriate ratios in order to maintain the homeostasis of skin barrier. The compositions, kits and methods can be used as cosmetics, cosmeceuticals or pharmaceuticals for improving skin condition, and preventing or treating dermatological diseases and skin disorders.

Abstract: This invention relates to the methods and pharmaceutical compositions for treating diseases or disorders associated with oxidative stress and/or genomic instability. In particular, the invention relates to methods for treating ataxia-telangeictasia (AT) and such disease states by administering a therapeutically effective amount of a chelating agent to increase genomic stability and/or decrease oxidative stress.
