Avoid being out in the sun too long as this could cause your skin to turn red or burn. If you are out in the sun in the United Kingdom or abroad then try to stay in the shade between 11-3pm and wear clothing that protects your skin.
Sunscreens should not be used as an alternative to clothing and shade; rather they should offer additional protection. Sunscreen protection never provides 100% protection against the suns harmful rays.
When choosing a sunscreen look for one which offers both UVA and UVB protection. It should be at least SPF 15 (in the UK, this is indicated by at least four stars and the circular UVA logo). Use water resistant products if sweating or in contact with water. Check the symbol on the back for how long they work for as out of date sunscreens can be dangerous to your skin.
When applying sunscreen apply thickly half an hour before going out in the sun (don’t forget your head, neck and ears). Re-apply at least every 2 hours and immediately after being in water, even if the sunscreen is ‘water resistant’. Also re-apply after towel drying.
