Nail Discoloration: Troubleshooting Yellowing Acrylics - NSI Attraction

Question
hi im a nail tech i recently purchaced " attention nail liquid NSI brand" i have had a client whos nails acrylic have turned dark yellow after 1 day of a refill mine go yellow on tips but not so sudden please help me

Answer
Tonya,
Do you mean you purchased ATTRACTION monomer?
What type of nail did you do? Pink and whites? I am going to assume that is what you did since you can see the yellow.
There are MANY things that can turn the product yellow.
* what top coat did you use? Was it a UV that prevents yellowing?
* does this client tan? Does she use tanning lotions?
* is she a smoker?
* did she use anything with a sunscreen?
* what powder did you use? Did you use NSI's powder? I think that only their UNIVERSAL monomers can be used with other brand powders.
* some nailtechs feel that if you use the same brush it will cause yellowing. Meaning, if you used, say Entity brand monomers and then used it with the NSI liquid, it could yellow. I have never had this happen to me.

You may want to go over these things with her.
Let me know how you make out.
buenos dias,
Lynnette
