It’s safe to slap on the sunscreen this summer – in repeated doses – despite what you have read about the potential toxicity of sunscreens.
A new study led by the University of Queensland (UQ) and University of South Australia (UniSA) provides the first direct evidence that zinc oxide nanoparticles used in sunscreen neither penetrate the skin nor cause cellular toxicity after repeated applications.
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.
