SPF protects you from sunburn from ultraviolet B (UVB) and ultraviolet A (UVA) rays.
Sunburn increases your risk of skin cancer and can occur wherever you are, even if it’s cloudy so it’s important to always wear SPF when your skin is exposed to sunlight.
Some top sun safety tips include:
- Spending time in the shade between 11am and 3pm when the sun is at its hottest
- Make sure you don’t burn by regularly applying sun cream and go indoors if you can feel your skin burning
- Cover up with suitable clothing and sunglasses if you cannot avoid being in the sun for long periods of time
- Use at least factor 30 sunscreen – but do not solely rely on this
Sunscreen should be applied to all exposed areas of skin regularly.
What factor sunscreen (SPF) should I use?
You should never solely rely on sunscreen to protect yourself from the sun.
When buying sunscreen look out for labels that have an SPF of at least 30 to protect your skin against UVB and at least four-star UVA protection.
When applying sunscreen make sure it is not past its expiry date – most sunscreens have a shelf life of two to three years.
How much sunscreen should I apply and how often?
Adults should aim to apply around two teaspoons of sunscreen to your head, arms and neck and two tablespoons of sunscreen if you’re covering your entire body whilst wearing a swimming costume.
If you don’t apply enough sunscreen or the layer is too thin the amount of protection it gives is reduced.
If you plan to be out in the sun for a long period of time you should apply sunscreen twice – 30 minutes before going out and again immediately before going out.
Sunscreen needs to be reapplied frequently and generously throughout the day – this includes after being in water, towel dying, sweating or when it may have rubbed off.
We recommend reapplying sunscreen every two hours as the sun can dry it off your skin.
