If there are bacteria in them, it will harm the skin. Accordingly, after cosmetic is used must seasonable screw tight bottle cap, lest bacterium invasions breed. It is better to avoid using it directly by hand and replace it with pressure or other tools. In addition, once cosmetics are used, such as face cream and lotion, they can no longer be put back in bottles to avoid contamination. They can put too much cosmetics on other parts of the body.
