What level of protection do I need?
Wear your sunscreen. Depending on your skin type, use a high SPF (sun protection factor). Your children should be using the highest possible factor available, such as factor 40. The higher the SPF, the higher the protection you will receive against dangerous sunburns. Make sure you rub in the lotion correctly and top up the application after a dunk in the sea or swimming pool.
It’s not cool to be red after being in the sun.
