Abstract
The present invention provides a composition for topical administration of a polyhydroxy acid, such as lactobionate and especially zinc lactobionate, and low pH to an external body surface such as skin. The composition is designed to be highly effective in delivering low pH and zinc lactobionate across the layers of the skin to more effectively treat and prevent skin conditions involving a defective skin barrier such as eczema and severe dry skin.
