I don't use anything. I tell new clients and remind regulars to moisturise well, paying attention to elbows, knees, heels, feet and hands. Night before to exfoliate well and apply a little moisturser to the key area's.
I've not had a problem yet. My clients stand on a small clean towel and I use a piece of couch roll to blend at wrists and toes when I'm done. While I'm doing that I remind them to moisturise every day and to use a bronzer on their faces when the tan fades off which is always quicker then the rest of the body due to makeup etc.
I use the small towel to clean up any over spray in the area and that's me done.
Just be relaxed, chat, check you haven't missed any where and you'll have them hooked:hug:
