The weather is getting hotter and hotter. How to store unnecessary cosmetics?

We are used to putting cleansing products in the bathroom, but the frequent bathing in summer, high humidity in the bathroom and too humid environment are taboos for cosmetics preservation. Humidity will accelerate the reproduction of cleansing bacteria containing protein and lipids, and finally deteriorate. In order to make the facial cleanser last longer, it is suggested that the bathroom must open the window or open the exhaust fan every day to "detoxify" the cosmetics, and pay attention to tightening the bottle cap of the facial cleanser.
