Wow, in amazed that this is happening to so many people. I'm in Venice Florida and went to Sparkle. It was happening while they were doing me. They removed first layer and did again. Told me to come back if it continues. It did after one day. I went back a week later as it was over Christmas. They removed and redid it. Now after a week it is doing it again. They said they never had it happen before. They said maybe it was a medication I was on. My meds have not changed in a year. It’s never happened before.

I am experiencing the same thing. The polish is turning yellow, sometimes after a week, now I noticed it as soon the manicure was done. I am not a smoker, nor do I use harsh chemicals. I could see the difference right at the salon.

Agreed! I noticed the yellowing of my French gel manicure after using Clorox wipes too. I also used Mr. Clean Magic Eraser the same day.
