I asked a few colleagues, and they answered: achieving what marketing wants while complying with regulations and making sunscreens esthetically pleasing (so consumers will use them); and the lack of international harmonization in UV filters, UVA testing and labeling. These issues are not new, so why are they not yet resolved? Perhaps because regulations and consumer demand are moving targets, which are difficult to hit.
