Today, the temperature is extremely high In the afternoon, I found that all the tubular cosmetics in my house suddenly swelled up. What is the reason?

It may be the gas produced by bacterial reproduction or the gas produced by chemical decomposition.

Cosmetics should be stored in a cool and dry place, not in the car or in direct sunlight, because high temperature will accelerate the decay of cosmetics.

Choose cosmetics that pay attention to packaging hygiene, because hygiene is a major factor to ensure the quality of cosmetics.
