In a warm area
In a cool, dry place away from direct sunlight
In direct sunlight

The correct answer is: In a cool, dry place away from direct sunlight

Cosmetic products should be stored in a cool, dry place away from direct sunlight to maintain their effectiveness and safety. Heat and humidity can promote the growth of bacteria and fungi, leading to contamination and potentially adverse reactions when the product is used. Sunlight can also break down the ingredients in cosmetics, reducing their efficacy and shelf life. Storing products in a cool environment helps preserve their chemical stability, which is essential for maintaining their intended performance. A dry area is crucial as moisture can lead to mold and spoilage. By keeping cosmetics out of direct sunlight, you protect them from degradation caused by UV exposure, which can compromise the integrity of various active ingredients. This storage practice ensures that the products remain safe for use and perform as expected.
