Dont mix them babe.
I would highly recommend you Do NOT use cnd primer with nsi products ..
you could find your self in a little mess if you do, lifting ...over exposure..a whole list of things.
If you put "mixing products" into the search bar, you should find a whole heap of information,
Did you not get the NSI primer too ?
I have been using NSI attraction for a couple of months now and havent had a problem with lifting at all hun..
So unless the product is out of date or anything like that..
I'm presuming it was just that your friend didnt get along with the products..
It took me a while to get the hang of NSI as it sets so fast compared to CND ...But same as you really, I bought a lot of another geek, so HAD to get my head around using it,
Now I have..Its fab hun.
But yeah please don't mix xxxxxx:hug:
