i think i know what is causing my reaction. i used the nuture oil when the nails were finished and massaged the oil into my nail and cuticle. and where it itches where the rash is now. i thought to myself it has to be the oil because the oil is the only product that touches up to my first knuckle, theres no way my acrylic product gets this far up my skin.

I understand what you are trying to say sammyjane, but I still think you need to consider that it may well be the L&P causing the problem. The reason I say this is that i started getting product sensititvity just from having enhancements applied to me and there was definitely no way the product was being applied half way up my fingers. Having it applied to my nail plate was enough to make my entire fingers and hands flare up!
I don't have a problem with cured gel, only uncured. When somebody applied L&P to me, I had my worst reaction. This is probably because L&P does not cure immediately so it continues to irritate the skin.
If you want to rule out the nurture oil, then apply a little to you toes (assuming you don't wear enhancements on your toes). If you have no reaction, then I think you can safely reason that the problem is not down to the nuture oil. HTH.
