Abstract (en)
[origin: WO2019195064A1] 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.
