The big 4 must haves
Sunscreens need to tick these four major boxes:
- The sun protection factor, or SPF, should be at least 30, preferably 50. SPF describes how much UV gets to the skin. SPF50 allows just 1/50th (2%) of the UV to reach the skin
- Go for broad spectrum protection, which filters the full UV light spectrum. UVB rays (290-320nm wavelengths) are responsible for most sunburn and DNA damage, but UVA rays (320-400nm) also cause DNA damage and accelerate skin ageing
- Aim for water resistant formulations, which stay on longer in sweaty conditions, and when exercising or swimming. But no sunscreen is completely waterproof
- Make sure the sunscreen is approved in Australia. Approval from the Therapeutic Goods Administration (TGA) is the final must-have. All sunscreens for sale in Australia must meet the TGA’s requirements and will carry an AUST number on the packaging. They can only contain ingredients from an approved list that have been tested for safety and efficacy. And the SPF, water resistance and broad spectrum action must be established by testing on human skin. Sunscreens bought overseas don’t necessarily have these safeguards, so proceed with caution.
