Liquid foundation is a liquid foundation, which is suitable for neutral, mixed and oily skin. Compared with the moisturizing effect of foundation cream, the oil control effect of liquid foundation is relatively better. Liquid foundation should select different product types for different skin types. Liquid foundation plays a protective role. It is the first step of makeup and the last step of skin care. It blocks dust in the air from entering the skin, so it plays a protective role. Moisturizing liquid foundation with high-efficiency moisturizing ingredients can "catch" the moisture in the air and "lock" the moisture in the skin, so it can moisturize the skin and is the most considerate layer of outer clothing for the skin. If the weather turns hot or if you have oily skin, foundation with oil control ingredients will bring better results. The bottle cap of liquid foundation that is not used for a long time must be tightened to prevent a large number of bacteria in the air from entering the bottle through the bottle mouth. Then store it in a cool and dry environment. If you find that the liquid foundation has oil and water separation and smells unpleasant. This indicates that the liquid foundation has seriously deteriorated. When applied on the face, it is easy to make the makeup on the face too dry due to the evaporation of oil and water. Moreover, thick foundation will clog the pores, which will cause various skin problems over time. When buying liquid foundation, avoid hoarding a large amount and use it up as soon as possible within one year after opening.

Liquid foundation can be kept for 2-3 years.

If the liquid foundation is not opened and used and is stored in a suitable environment, it can be used within 2-3 years. However, the shelf life of the liquid foundation that has been opened and used has been greatly shortened. Its best use time has been reduced to six months or one year. The outer packaging of the liquid foundation will indicate its shelf life, but this shelf life refers to the unopened use time. If the shelf life marked on the instruction manual is 1-2 years, the actual shelf life of the liquid foundation after opening is six months, and the longest will not exceed one year. If the shelf life on the instruction manual is 2-3 years, the best use time of the liquid foundation is up to 18 months, but it is best to use it up within one year. After the actual shelf life of the liquid foundation, even if there is no deterioration, it is best not to continue to use it. Because after the best use time, a large number of bacteria will breed inside the liquid foundation, and the color and shape of the liquid foundation may also change. Direct application on the skin may affect the makeup effect, and may also cause dull skin and even allergies. There are many kinds of liquid foundation in the beauty market. Sometimes, out of curiosity and love for new products, people tend to stock up on a large amount of liquid foundation. As a result, the liquid foundation will be put aside after being used a few times, and the liquid foundation will become expired and deteriorate. Therefore, the opened liquid foundation should be used up as soon as possible within six months or 12 months.

Liquid foundation will not go bad if it is stored in a plastic bottle. If the liquid foundation cannot be used up in a short period of time, you can prepare clean sub-bottles to sub-package the liquid foundation. Generally, sub-bottles are made of plastic. When sub-packaging liquid foundation, make sure the inside of the bottle is clean. Sub-packaging liquid foundation can reduce the deterioration of liquid foundation due to oxidation, because frequent opening of the lid makes it easy for bacteria to grow.
