Photochemistry and Photobiology, Volume 101, Issue 2, Page 338-349, March/April 2025.In the present work with mouse models, we demonstrate that a novel compound, NEO400, is able to profoundly protect skin against damage caused by UV radiation (UVR) when it is applied to skin post‐UVR exposure. In comparison, Aloe vera or linoleic acid are unable to achieve a similar level of protection.
