$EAPH EASTON PHARMACEUTICALS, Inc. (formerly LAM) scientists discovered that certain molecules called polymers possessed strong electrical charges which, when combined with other polymers of a specific electrical charge, are able to effectively help transport agents through the outer layers of the skin. In addition, these molecules are able to attach or surround other molecules such as therapeutic molecules and carry them within a matrix through the outer layers of the skin Easton Pharmaceuticals (formerly LAM) scientists recognized that these discoveries would be of great significance in regard to the delivery of therapeutic agents.
