How long can a bottle of liquid foundation last?

Everything has a shelf life and a use period. After all, it is consumed every day, including cosmetics. The use period of cosmetics is determined by personal factors. Some people with big faces use less makeup, or she may have to put on makeup many times a day, which will cause the makeup to wear out quickly. However, most people don't know the use period of a bottle of liquid foundation under normal use. So how long can a bottle of liquid foundation be used?

Generally, 30 ml of liquid foundation is designed for 4 to 6 months of use. It is not recommended to apply liquid foundation on the neck, which will stain the clothes. You can buy liquid foundation according to the color of the neck. I want to know why you have to wash your face before applying foundation at noon? Generally, when you touch up your makeup at noon, just pat the foundation on the makeup-off area. If you touch up your foundation because your skin is oily and you have almost lost your foundation, then choose a long-lasting or oil-control one. If you don't like to take a nap with makeup on, just use BB cream. I still spend a lot of money on foundation products. I like a slightly thicker foundation. A bottle of foundation lasts about half a year. If you use it for three or four months, it's about three to four months. If you use up a bottle of foundation in a month, then you are applying too much and it's not necessary.

First of all, when we buy liquid foundation, there is usually a shelf life marked on the bottle, but this shelf life does not represent how long the liquid foundation can be used after opening the bottle. Because cosmetics generally have two shelf lives, one is before opening the bottle, and the other is after opening the bottle. For example, the shelf life of liquid foundation before opening the bottle is generally three years, of course there are some differences. Because cosmetics are sealed before opening the bottle, they can be stored for a relatively long time.

Since the shelf life of liquid foundation before opening the bottle is three years, can it also be used for three years after opening the bottle? Of course not, because the liquid foundation is in a sealed state before opening the bottle, but after opening the bottle, the liquid foundation is exposed to the air and will come into contact with the air and various microorganisms in the air, so naturally it cannot be used for three years. Generally, the shelf life of liquid foundation is one year after opening the bottle, which means it must be used within one year after opening the bottle.

People who wear makeup frequently will choose foundation products according to their preferences and needs. Because there are indeed many kinds of foundation products, and there are many innovative products on the market, many people who are new to makeup don’t know how to choose foundation products. Liquid foundation is a base makeup and concealer product. It has a good concealer effect and is generally light and transparent when applied. However, compared with other base makeup and concealer products, liquid foundation may have a coarser powder texture, so you can choose liquid foundation based on your own acceptance.
