Modulation of zinc levels and tissue properties: Essentia Biosystems discloses the modulation of zinc levels to improve tissue properties. Methods of altering the properties of tissues were explored by modifying the amount of zinc, which may be in the form of zinc ions, through the use of topical compositions containing one or more zinc-containing components such as salts and/or other zinc compounds or in complexes, particularly zinc acetate. By altering the zinc levels, researchers found they were able to increase or decrease fatty tissue, increase or decrease epidermal thickness, increase elastin content, and prevent or treat gum regression or atrophy.
