Bronzinc is a tinted australian sunblock containing zinc oxide and octyl methylcinnamate to provide photostable uva/uvb spf 30 protection. It's fairly thick and takes a little while to rub in, but is not too greasy and is water resistant for 4 hours. Don't be put off by the colour in the tube. It look lighter once put on the skin. Anyone who finds it too dark in colour could try mixing it 50/50 with a clear zinc. At around $5-6au for a 50 gram tube, compare that in price to the Megan Gale tinted zinc, and you'll see that it's a bargain if you are able to wear chemical sunscreen ingredients.
