In hot summer, will cosmetics deteriorate because of the hot weather?

High temperature will make cosmetics water and oil differentiate or deteriorate, so it should be stored in a cool place to avoid direct sunlight.

The maximum acceptable temperature of cosmetics is 30 degrees, which exceeds the situation that water and milk will separate. Therefore, when using cosmetics in summer, we must pay attention to the following two points:

1, strong ultraviolet rays have certain penetrating power, and it is easy for oils and spices to oxidize and destroy pigments. Therefore, cosmetics should be kept away from light.

3. Cosmetics should be stored in a heat-proof place, and the temperature should be lower than 30℃. If the temperature is too high, the emulsification of cosmetics will be destroyed, resulting in the separation of fat and water, drying shrinkage and deterioration of cosmetics.
