How should nail polish be stored for best results?

Nail polish should be stored in a cool, dry place away from direct sunlight to ensure its longevity and maintain its quality. Storing polish in a temperature-controlled environment helps prevent the formulation from thickening or separating, which can occur when exposed to heat. Direct sunlight can degrade the polish, alter its color, and affect its consistency, leading to poor application and performance.

While options suggesting a humid environment or direct sunlight may seem tempting for different cosmetic products, they are detrimental to nail polish. Keeping nail polish at room temperature alongside other cosmetics might be convenient, but without the protection from light and temperature fluctuations that a cool, dark area provides, the polish may still suffer. By adhering to the first option, the integrity of the nail polish is preserved, ensuring optimal results during application.
