The inventive subject is directed towards ready-to-use topical cosmetic formulations that include at least one defensin present in sub-antimicrobially effective concentrations. Surprisingly, even at such low concentrations, defensins recruit LGR6+ stem cells from hair follicles to the interfollicular space. Including defensins in the inventive topical cosmetic formulations may reduce one or more of wrinkle depth, wrinkle length, wrinkle width, pore size, irregularity in texture of a skin surface, oiliness, brown spots, and red spots in non-injured skin, thus reducing apparent age.

Compositions comprising an aqueous medium, lipids and nonionic surfactants and methods of their use in preventing skin damages, such as in subjects exposed to radiation, are provided.

Extracellular vesicles derived from native, photosynthetic, non-fermenting microalgae are provided. A method for isolating extracellular vesicles from native, photosynthetic, non-fermenting microalgae involving growth, centrifugation and ultracentrifugation steps is also provided. Use of the isolated extracellular vesicles as carriers for deliverling diagnostic, therapeutic, nutraceutic and/or cosmetic agents is further provided.

Milk fat globule membrane (MFGM) phospholipid compositions, methods of preparing and using the MFGM phospholipid compositions, liposomes comprising the MFGM phospholipid compositions, and methods of preparing and using the liposomes comprising the MFGM phospholipid compositions. In various examples, a MFGM phospholipid composition is formed by sequential supercritical carbon dioxide (SC—CO.sub.2) extraction of a milk product and extraction of the remaining milk product with a polar compound-modified SC—CO.sub.2 extraction, where the extract is the MFGM. In various examples, the MFGM is used to prepare liposomes. In various examples, the liposomes are prepared by expansion of a supercritical solution comprising the MFGM composition. In various examples, the liposomes are used to administer a cargo, such as, for example, hydrophilic compound(s), hydrophobic compound(s), amphiphilic compound(s), or the like, any one or all of which may be therapeutic agent(s), nutrient(s), bioagent(s), or the like, or any combination thereof to a subject.

The present invention provides a recombinant exosome comprising a membrane-bound EGF protein on the surface of the recombinant exosome and provides a use of the recombinant exosome.

A method and system in accordance with a particular embodiments of the technology includes applying a substance onto skin of a human subject. The applied substance can include a freezing point depressant and a liposome, an oil-in-water emulsion, a water-in-oil emulsion, or an oil-in-oil emulsion and can be configured to protect or target tissue. The substance and a surface of the skin can be cooled using the applicator to treat acne and other skin conditions.
