facial scrub

Being in the sun means factor 50 for my delicate skin. I have a canopy which means I am working in the shade most of the time but I need to walk around occasionally, I talk to the other artists, get a drink etc, so factor 50 it is, this needs topping up regularly. However by the time I have done 5 minutes carving I am covered in a fine layer of dust so putting on the sun cream gives me a facial scrub, some people pay a lot of money for that- maybe this rugged form of exfoliation could catch on.
