How should makeup products be stored to prevent contamination?

Makeup products should be stored in a cool, dry place and away from direct sunlight to prevent contamination and maintain their integrity. Heat and humidity can encourage the growth of bacteria and mold within products, especially those that are cream-based or contain water. Direct sunlight can cause chemical changes in the formulation, leading to alterations in consistency, color, and effectiveness.

Storing products in unsuitable environments, such as a warm, humid space, can compromise their safety and shelf life. While a refrigerator may preserve certain products, it is not universally applicable for all makeup items, as some may be adversely affected by cold temperatures. Similarly, placing makeup in a bathroom cabinet can expose it to humidity and fluctuations in temperature, which could lead to contamination. Therefore, choosing a stable environment that minimizes exposure to elements harmful to the products ensures their longevity and safety for use.
