When my polishes arrived, I noticed that I had received one of the old formula polishes and one of the new formulas.
The new formula is slightly lighter in color. The new version is on the left and the old version is on the right.
I decided on doing a comparison between the two to see if there was a noticeable difference on the nail.
The new formula is on my Index and Ring fingers. The old formula is on my Middle and Pinky fingers. You can see a slight difference in the colors but it's very minor. The difference is hardly even noticeable in the shade. Both polishes have the same great jelly formula.Hope this helped!
