Violet Wands & Itchy Skin

I was using a Violet Wand on a lady Friday night. During our post-scene check in, she brought up 1 concern which I've pasted below. > The only concern I have with trying them again is that for the next two days my breasts/chest and back were exceptionally itchy. > (breasts still are) I'm not certain it's related, but deductive reasoning would follow that it is. Have you ever heard of this? I've > been putting on cortizone cream and that seems to help for a few hours. It's not unbearable, but if the reaction is related, I'd think > twice before doing it again. Anyone have any idea whether the 2 ARE actually related? I personally have experienced a slight reddening of the skin (similar to a low-grade sunburn), but not itchyness AFTER the scene....during the scene, a little...but not after.
