Systems for treating a surface comprise a first composition and a second composition. The first composition comprises a water soluble organic photoactivator. The second composition comprises an electron acceptor which accepts an electron from the photoactivator when the photoactivator is in a photo-excited state and/or reduced state and a benefit active precursor which converts into a benefit active agent via electron transfer. Methods for treating a surface comprise applying the first composition to the surface, applying the second composition to the surface, and exposing the surface to light.
