1. Use cosmetics during the shelf life to prevent skin infections
There may be a lot of cosmetics that are not used up when the season is coming. For example, the high-grade lipstick oozes sweat, the nail polish is a little dry, the perfume seems to have changed its taste, the moisturizing effect of the lotion seems to be not stable, and the acne gel fails.
Why does cosmetics expire?
Do you know what is going on? In fact, like all chemical mixtures, cosmetics are exposed to oxygen, bacteria, hot gases or due to humidity changes during use, which can react with the environment and affect their efficacy. However, you don't have to urgently clean the dressing table. You only need to know the reasons for the change in the concentration, taste and color of the cosmetics, how to prevent these changes, and when to throw them away, in order to accurately "change makeup"!
