What is the recommended way to store nail polish?

Storing nail polish in a cool, dark place is recommended because heat and light can degrade the quality of the polish, leading to changes in viscosity or color. Exposure to high temperatures can cause the polish to become thick and difficult to apply, as the solvents may evaporate. A dark environment reduces the risk of light-induced breakdown of the ingredients, helping to maintain the polish's consistency and color over time. This method of storage ensures that the product remains effective for longer, allowing for better performance during application. Other storage options, such as a warm area or in direct sunlight, will not preserve the nail polish as effectively. Additionally, while the bathroom may seem convenient due to its proximity to use, it often experiences humidity changes which can negatively affect nail polish. Keeping nail polish in the refrigerator can be excessively cold, leading to separation of components, which further detracts from its intended use.
