How should nail polish be stored?

Storing nail polish in a cool, dark place away from direct sunlight is essential for maintaining its quality and longevity. Heat and light can cause the pigments in nail polish to break down, leading to changes in color and consistency. A stable, cool environment helps prevent the polish from thickening and keeps the formula intact for longer periods.

While the idea of storing nail polish in the bathroom may seem convenient, the humidity and temperature fluctuations often found in bathrooms can adversely affect the polish. Similarly, while refrigeration might seem like a way to preserve the formula, it could also lead to condensation inside the bottle, potentially causing the polish to separate or become unusable. Overall, maintaining a cool and dark space is optimal for preserving nail polish integrity.
