In this quick episode, Dr Tanya and Dr Sumreen cut through the recent sunscreen controversy to explain one simple thing that can change your entire skin cancer risk — the AUST L number. It's a short, practical watch on how to actually choose a sunscreen that works.


What You'll Learn:

  • What the AUST L number is, and why it matters for choosing a real, TGA-approved sunscreen
  • The difference between "listed" and "registered" sunscreen products
  • Why some sunscreens are only cosmetic-grade and don't actually protect you
  • How often to reapply, and when to put it on before sun exposure
  • SPF 50 vs SPF 30 — what's the actual difference?
  • Why broad-spectrum protection (UVA and UVB) is essential
  • A reminder to pair sunscreen with the classic "slip, slop, slap" precautions
