Will cosmetics deteriorate if the weather is too hot in summer?

If the weather is too hot in summer, cosmetics will deteriorate.

Excessive temperature will cause the oil and water of cosmetics to separate, causing the paste to dry and shrink, causing deterioration. It is not advisable to store cosmetics in places exposed to direct light, because light exposure will cause the moisture in the cosmetics to evaporate, and some ingredients will lose their vitality, causing deterioration. Ultraviolet rays in sunlight can also cause chemical changes in some substances in cosmetics, affecting the use effect and even causing adverse reactions.
