It’s not just what sun protection you use, but how you use it and what you use with it.

Remember these pointers:

1. Use a sunblock with at least SP15. It can block 93.3 per cent of UVB rays – SPF8 only blocks 57.5 per cent of UVB rays.

2. All sun protection covers only 50 per cent of free radical damage. Use an antioxidant product beforehand for more protection.

3. Generally, the higher the SPF, the more chemicals the product has. The more frequently you use the product, the more it will lead to sensitized skin – rashes flaky skin and breakouts. Choose a sunscreen with physical blocks (such as titanium dioxide or zinc oxide) instead.

4. No matter how high the SPF is, all sunblocks last up to 80 minutes in water – some last only 40 minutes. Reapply often.

5. Removing sunblock is as important as putting it on. This prevents product build-up and clogging. Use a cleansing oil to remove water-resistant sunscreens.
