I would love to see an improved formula [SEP] It is so so hard to find vegan nail polish so I will definitely continue buying these, but I am just hoping to see improvement in one area in specific. The colors are beautiful and pigmented, they don't chip easily, but it does leave a yellow stain on my nails after removal.  No other nail polish has ever done so, and it makes me wonder about what may be causing it. Only areas with the polish have been stained yellow.
