It is too hot in summer. Will cosmetics go bad?

High temperature will cause water and oil differentiation or deterioration of cosmetics, and it will also deteriorate due to expiration or improper storage. Using deteriorated cosmetics can easily lead to facial injury or skin allergy.

Cosmetics enter the "countdown" state as soon as the bottle cap is opened, especially when the temperature is high in summer. Ultraviolet rays have a certain penetrating power, which easily oxidizes oils and spices and destroys pigments. Therefore, cosmetics should be kept away from light.

Deteriorated cosmetics give off an unpleasant smell, and the color will also change, indicating that the oil composition inside has changed, which will be very irritating to the skin.
