SPF - everything you need to know

How to choose a good sunscreen.

UVA & UVB broad spectrum protection

SPF stands for sun protection factor and refers to the ability of a sunscreen to block ultraviolet B (UVB) ONLY, not UVA. It offers an insurance against sunburn but not against photo ageing. Always look for a UVA & UVB sunscreen.

Sunscreen is NOT water resistant

This is a marketing trick. Sunscreens are no longer allowed to be labelled as “waterproof” or “sweat proof” because these terms can be misleading. No matter what is written on the bottle always reapply your sunscreen after swimming or exercising.

SPF 15 or higher

The difference between LOW and HIGH SPF is very small, just 5%, i.e. SPF 15 offers 94% protection, when SPF 50 offers 99% protection. 

Use SPF correctly

NO sunscreen offers 100% protection. That’s why the SPF number is not as important as using the sunscreen correctly especially when exposed to direct sunlight.

  • Use a lot
  • Apply 20 minutes before going out
  • Reapply every 2 hours if staying outdoor
  • Reapply after exercise or swimming
  • Pay close attention to your face, ears, neck, arms, and any other areas not covered by clothing
  • If you’re going to wear makeup, put your sunscreen on first
  • Use broad spectrum sunscreen (UVA & UVB protection)
  • Don’t use expired products, they lose their effectiveness
  • Never rely on sunscreen alone, wear sunglasses, hat, and cover your body with clothes
