Nail polish can cause discoloration.
Some colors (pigments) can penetrate the nail, especially darker polishes. Also, “nail hardeners” such as formalin and dimethyl urea can cause yellowing when it reacts with the keratin protein in your nails.
A base coat may help. The primary reason to apply a clear base coat first is to form an even surface for applying the color polish. It may also serve as a barrier to reduce the likelihood of nail discoloration.
So what should a person do? Let your nails “breathe” for a few weeks without polish. This may help them return to a normal hue.
Take heed. Sometimes injury or fungus that was covered becomes apparent when the polish is removed.
