Thus, on hot summer days, we should not keep to many cosmetics in our handbag, and it’s best to use them up at short notice. The proper reserve temperature should be under 35 degrees.
2. Sun proof
Places full of sunshine or lights are not proper to keep cosmetics, because if they are exposed to the sunshine or lights, water will evaporate, some ingredients will lose their activity to age and deteriorate. Besides, cosmetics contain large amount of chemical substances, so chemical reactions which can lead to effectiveness reduction will happen by mean of sunshine ultraviolet ray irradiation. Therefore, do not keep your cosmetics outdoors, on the balcony, or by the table lamp etc., Meanwhile, when you purchase cosmetics, do not buy the sample products in the cabinet, because of light irradiation in the cabinet for long term, they may or have already deteriorated.

5. Pollution proof
Although preservatives are added into the cosmetics to keep them from pollution and deterioration, but pollution and deterioration can not be avoided completely, if there is any bacteria in the cosmetics, they will damage you skin. Therefore, after using them, you should tighten up their covers promptly in case the bacteria invade and reproduce. When you use them, it’s better to use a pump or other kinds of tools instead of your hand. Besides, once used, cosmetics like face cream and latex should not be put back in the container to avoid pollution, you should apply the extra cosmetics on the other part of your body.
