note! Expired cosmetics equals poison

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, the moisturizing effect of the emulsion 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, there is no need to urgently clean the dressing table. Just grasp the reasons for the changes 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"!
