When does my nail polish expire?
An estimate based on general guidance or your label. Always follow the product's own label, and replace anything that smells, looks or feels different.
Why polish gets thick
Nail polish thickens when solvents evaporate. essie points to two causes: bottles that are not closed tightly, and polish left on the neck of the bottle, which dries and stops the cap from sealing. Wiping the neck after each use keeps the seal tight.
Cold storage
essie says nail polish can be stored in the refrigerator or even the freezer. A cool, dark place slows evaporation, which is what thickens polish, and it also protects the color from light. Let a cold bottle come back to room temperature before painting your nails.
