Abstract
Embodiments of the invention include topical compositions comprising silica fiber powder or dust and a topical carrier, for treatment of skin tissue. The silica fiber powder or dust may be generated from silica fiber mats that may be formed via electrospinning of a sol gel produced with a silicon alkoxide reagent, such as tetraethyl ortho silicate, alcohol solvent, and an acid catalyst.
Claims23
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.
