Described here was an in vivo model to determine antioxidative capacity of a topical skin care emulsion versus the emulsion’s vehicle on human skin that was exposed to UVR. Results suggest the test emulsion and its vehicle control inhibited the induction of erythema and reduced inflammation caused by the UV exposure.
