1. Eyeliner and liquid eyeliner

If there are white heads on the tip of your eyeliner that cannot be trimmed off, you should throw them away. If the eyeliner you apply comes off very easily, it's a sign that the eyeliner is expired. The lifespan of liquid eyeliner does not exceed half a year, while the lifespan of eyeliner pencil is generally around 1 year.

2. Mascara

Generally, it is safer to replace a mascara every 3 to 4 months. If your mascara smells like gasoline, or clumps up, or granules appear on your eyelashes when applied, you should stop using it immediately.

3. Eyeshadow

In fact, the shelf life of powdered eye shadow is generally about two years. Remember to clean your eyeshadow brush regularly, otherwise a lot of bacteria will be brought into the eyeshadow palette. If you are used to applying eye shadow with your hands, be sure to wash your hands before applying makeup.

4. Liquid foundation

It turns out that liquid foundation is a breeding ground for bacteria. Unopened liquid foundation can be stored for many years, but once opened, it must be used up as soon as possible within six months to a year. Expired foundation will emit an unpleasant odor and its color will change, which means that the oil composition inside has changed, which will be very irritating to girls' skin.

5. Concealer

Like liquid foundation, expired concealer will change color and look oily when applied to the skin. This is because the oil in the expired concealer will rise to the surface. The lifespan of concealer is no more than one year.

6. Loose powder and powder

The shelf life of general honey powder and loose powder is about 2 to 3 years. Some loose powders containing plant essences contain a small amount of moisture, so be sure not to place them in humid places such as the bathroom to avoid breeding of bacteria. If your loose or face powder starts to clump, turn gray, or turn green, just throw it away.

1. Cleanser

Causes of deterioration: Usually stored in the bathroom, frequent bathing in summer, heavy humidity in the bathroom. Moisture can accelerate the growth of bacteria in cleansers containing lipids or proteins, causing them to deteriorate.

Solution: Do not place facial cleanser in the bathroom in summer, keep the bathroom well ventilated, and cover the facial cleanser lid in time.

2. Make-up water

Cause of deterioration: When I went to a counter to try out the lotion in the summer, it was actually warm. In fact, it was heated by the light at the counter. Please note: Toner should not be placed near light sources, especially in direct sunlight, as high temperatures can easily cause it to deteriorate.

Solution: Products such as lotions can be put back into the original packaging and placed on the bottom shelf of the refrigerator. Do not place them directly next to the refrigerator door, because the exchange of cold and hot air during the opening and closing of the door is most likely to cause the product to deteriorate.
