Abstract
A topical skin composition and methods for its use are described. The composition can include a plurality of first plasmonic noble metal nanostructures having an aspect ratio of greater than 1 and being configured to absorb electromagnetic radiation from an artificial light source and/or from a solar radiation source to produce a first localized surface plasmon resonance (LSPR), and a plurality of second plasmonic noble metal nanostructures having an aspect ratio of greater than 1 and being configured to absorb electromagnetic radiation from a solar radiation source to produce a second LSPR.
