Note: You’ll notice that most retailers only keep the SPF50 version theses days because the Therapeutic Goods Administration (regulatory body for therapeutic goods in Australia) announced a new standard for sunscreens sold in Australia back in 2012, increasing the maximum sun protection factor from SPF30+ to SPF50+.

- The 'sun protection factor' (SPF) measures the degree of protection against UVB radiation
- The 'broad spectrum performance' measures of the degree of protection from UVA radiation
- SPF50+ filters out 98% of UVB radiation, while SPF30+ blocks out 96.7% of UVB
- UVB is mainly responsible for sunburn
- UVA penetrates deeper into the skin than UVB radiation and is considered to be mainly responsible for the longer term damage resulting in melanomas and other skin cancers
