Should nail paints be kept in refrigerator?

Nail paints do not need to be kept in the refrigerator, as storing them in a cool, dry place away from direct sunlight is generally sufficient. However, refrigerating them can help prolong their shelf life, especially in warmer climates, by preventing thickening and separation. If you choose to refrigerate them, make sure to let them return to room temperature before use to ensure proper application.
