2. The skin microbiota modulation device of claim 1 , wherein the cold plasma assembly is configured to generate a cold plasma stimulus having one or more of electrically charged particles, electrically uncharged particles, electrons, ions, and molecules.

3. The skin microbiota modulation device of claim 1 , wherein the cold plasma assembly is configured to generate a cold plasma stimulus having one or more of Argon, Heliox, Helium, Nitrogen, and Oxygen.

4. The skin microbiota modulation device of claim 1 , wherein the cold plasma assembly includes at least one of an atmospheric pressure plasma jet, a dielectric barrier discharge plasma actuator, a gliding arc device, a piezoelectric direct discharge plasma device, a plasma actuator, a plasma needle, and a plasma pencil.

5. The skin microbiota modulation device of claim 1 , wherein the cold plasma assembly is configured to generate a cold plasma stimulus of a character and for a duration sufficient to modulate the activity of skin microbiota on the biological surface.

6. The skin microbiota modulation device of claim 1 , wherein the cold plasma assembly is configured to generate a cold plasma stimulus that is less than 60° Celsius at the point of application.

7. The skin microbiota modulation device of claim 1 , wherein the cold plasma assembly is configured to generate a cold plasma stimulus that is less than 40° Celsius at the point of application.
