1. A method for treating damaged skin tissue in a subject, the method comprising:
applying silica fibers directly to the damaged skin tissue as a thin fiber layer sufficient to cover a surface of the damaged skin tissue, and applying additional silica fibers to the damaged skin tissue when fibers are no longer visible on the damaged skin tissue; and
after formation of new skin over the damaged skin tissue, applying a topical composition to the new skin, the topical composition comprising (i) a silica fiber powder or dust, and (ii) a topical carrier.
