We've all been there at some point - we've left the suncream and gone too long without reapplying or accidentally fallen asleep in the baking heat and woken up a shade to rival Larry the Lobster.
Sunburn is never pleasant - it's sore, makes the skin feel tight, and can even increase your risk of skin ageing and skin cancer.
