Our government has done a lot of research on sunscreen. The important facts are in a report called "The Burning Facts" by the EPA which you can easily "Google". The salient points are:

- SPF over 30 is a waste of your money and SPF only measures protection from UVB rays, not cancer causing UVA rays (it is actually illegal in Australia to claim an SPF over 30 for that reason).
- The only active sunblock ingredient that provides "extensive protection" from both UVA and UVB rays is zinc oxide
Separately, I happened to be in a dermatologists office today and an American Academy of Dermatology poster stated that 80 % of skin damage is typically done by the time you are 18 years old. Protect your kids early!
In the interests of full disclosure, I am Managing Partner in Z Blok sunscreen which has zinc oxide. So if on doubt read "The Burning Facts" to get the real facts.
