Abstract: Accordingly, a need has arisen for improved compositions, methods, devices, and systems for skin care including, without limitation, topical compositions and phototherapy devices and methods. A skin care method may comprise, in some embodiments, contacting at least a portion of the skin of a subject with a homogeneous, stable, self-foaming composition, illuminating the at least a portion of the skin exclusively with light of a desired wavelength (e.g., from about 390 nm to about 430 nm, and contacting the at least a portion of the skin with an anti-oxidant serum composition.
