The research, published this week in the Journal of Investigative Dermatology, refutes widespread claims among some public advocacy groups – and a growing belief among consumers – about the safety of nanoparticulate-based sunscreens.
UQ and UniSA lead investigator, Professor Michael Roberts, says the myth about sunscreen toxicity took hold after previous animal studies found much higher skin absorption of zinc-containing sunscreens than in human studies.
