Used this on myself and my 3 1/2 yr old while on holiday in Fiji to protect against dengue fever mosquitos. A very thick sunscreen but the white layer disappeared after a while. I am normally the first one to get bitten if any mozzies are within miles, and I didn't get bitten once. Nice to be able to apply the sunscreen and insect repellent in one go. Also used the spray on Badger insect repellant at night and its not too stinky and worked a treat without any Deet.
