You need a little Aloe Vera rubbed in to those sore spots....
Noooo allergic to aloe vera!
Bloody washing powder last time I looked, or have I missed some radical new development?
So anyway, that therefore begs the question, WHY would you want to rub clothes washing powder on your sunburn, or am I just plain thick, and NO, that last bit WASN'T a question requiring a one word answer thank you.
