Abstract
Disclosed herein are compositions that can be used to create a thin film on the skin of a subject in a single application step to the skin of the subject. More specifically, a composition provided herein does not have to be stored in multiple compartments, nor mixed with another composition or component before application to the skin. Instead, a single composition can be manufactured, stored in a single compartment, and then applied to the skin of a subject to create a film on the skin of the subject. In certain embodiments, because there is no need to mix a composition provided herein prior to application to the skin, the container comprising a composition provided herein may also include an applicator suitable for application of the composition to the skin.
