1. Functional cosmetics should be used as quick as possible.
In the case of functional cosmetics, if the available substances exist no more it ends up as nothing but a simple moisturizing substance. Once opened the contents inside will meet with the oxygen in the air continuously which will cause the substances inside to disappear. Vitamin C is especially quicker than other substances.
2. Protect your cosmetics from direct sunlight and the alteration of temperature.
If it's too cold or too hot in the winter or summer, or if you keep your cosmetics near a window you should move your cosmetics right away. If your room temperature doesn't change a lot it is the right place to keep your cosmetics. Direct sunlight or alteration of temperature may spoil your contents.
3. It is best to use cosmetics contained in tubes.
the container of cosmetics decides the expiration date of that product. The most effective container is tubes or pumping containers. It prevents the product go bad and protects the substances inside the product.
4. Most families tend to share their cosmetics among each other. If not avoidable, then you should always take out the amount you need then use it, using it directly is not hygienic. In the case of cosmetics which are used on the skin directly, you should use your own cosmetics.
