All of the following result from completely removing the former toenail polish EXCEPT?

When toenail polish is removed, various effects can be observed on the nails. One of the outcomes is that discoloration can indeed be reduced or eliminated, especially if the polish was dark or left on for an extended period. However, completely removing toenail polish does not guarantee that discoloration will vanish entirely, particularly if the nails have been stained by the polish or if there has been any underlying nail damage.

On the other hand, removing polish can lead to strengthening the nail, as it allows the nail to breathe and may prevent issues caused by prolonged exposure to chemically-laden polish. Improved nail appearance is also a common result, as removing polish reveals the condition of the natural nail, which may be more aesthetically pleasing. Additionally, without the barrier of polish, the nails can absorb moisture better, leading to a healthier appearance overall.

The nuance of the question lies in the expectation of the removal process. While many benefits can be gained from the act of removing polish, assuming that discoloration will vanish is not always correct, making it the exception among the other outcomes.
