Best Sunscreens

  • Sunscreens protect the skin from ultraviolet (UV) radiation which can lead to skin cancer
  • They can come in gel, cream or milk form
  • Any of these methods of delivery are good depending on your skin type, but they should always be applied very liberally
  • Sunscreens contain both chemical absorbers and physical blockers to protect you from UV radiation
  • The Sun Protection Factor (SPF) is a measure of the strength of the sunscreen
  • SPF 30+ is the best, and an SPF 50+ will be coming out next year, although it will not provide much more protection
  • What does sunscreen contain?

  • Sunscreen contains one or both of the following types of active ingredients:
  • Chemical absorbers which absorb UV radiation and stop it reaching your skin.
  • Physical blockers, which are zinc oxide and titanium dioxide, that reflect and scatter UV radiation.
  • What is SPF?

  • SPF stands for Sun Protection Factor.
  • The SPF number is only a guide to a sunscreen's protection properties.
  • In laboratory conditions SPF30+ sunscreen filters 96.7% of UV radiation. It is anticipated that SPF 50+ will become available in Australia in late 2012. However, SPF50+ sunscreen will provide only a negligible improvement in protection over SPF30+ from 96.7% to 98%.
