What is the shelf life of cosmetics?

Cosmetics usually do not indicate the period of use after opening. If you don't pay attention, you may use expired cosmetics, which will damage the skin. Therefore, you must have a cosmetic shelf life and learn to correctly identify and dispose of expired cosmetics.

The shelf life indicated on the cosmetic packaging is the longest shelf life of the cosmetic in a sealed package at normal temperature. From the moment the cap of the cosmetic product is opened, its use period enters the “countdown” state. Depressed is When it is time to discard products is always not so intuitive. Usually skin care products do not indicate the period of use after opening, even if it is just a simple recommended date of use. So learning to correctly identify and process expired cosmetics is a very important thing! Let's take a look at a few key points to extend the life of your product and the criteria for measuring whether you can discard it. Quickly make a big finishing of your cosmetics!

Powder or loose powder: 6 months - 2 years

When should I replace the powder? This is a rather troublesome thing. The powder will deteriorate, but unlike the cream, it can be distinguished from changes in odor or color and texture. Although the powder is very dry, bacteria are difficult to survive in the absence of water, but some cosmetic formulations add water or moisturizing ingredients such as aloe vera, jojoba oil or shea butter, which will undoubtedly shorten the life of the powder. If you don't notice it, the bacteria on your face will contaminate the powder by painting. In order to reduce this risk, the makeup brush should always be cleaned with a special antibacterial brush. If the texture of the powder changes, it produces particles that are difficult to fuse and cannot fit on the skin, then it should be discarded.

Eyeshadow: 6 months

Eye shadow powder: 2 years

Although the shelf life of eye shadows tends to be longer than other make-up products, care should be taken to identify signs of deterioration. If the color of the eye shadow changes or a waxy substance is produced, it should be stopped immediately. In order to maximize the life of the eye shadow, try to buy products with less color and smaller specifications. In addition, if eye shadow is often wet, then even eye shadow powder should not exceed 6 months of use.

Lipstick: 2 years

Although lipstick can be used for a long time, please keep in mind that it contains water, moisturizers and hydrating ingredients, which are easily infected by bacteria. In addition, it will dry out and be difficult to apply. When the lipstick is dry, there is a waxy substance that appears or becomes odorous (the original taste of the deteriorated lipstick is similar to a crayon) and it should be discarded.

Foundation: 6-12 months

In addition to powdery foundations, liquid foundations and foundations for hydraulic bases or essential oil bases can be a breeding ground for bacteria. The foundation will become discolored and discolored as the use time and exposure time under photothermal heat are prolonged. These are clear signs that you need to discard and replace new products. Avoiding the use of foundation products in wet and hot environments is a good way to extend their lifespan.

Concealer: 6-12 months

Covering creams usually use essential oils or humectants, such as jojoba oil or shea seed, which are usually smooth in texture and easy to fit into the complexion. If it is difficult to integrate into the skin after application, it becomes dry, agglomerated, or has a musty smell, then it should be discarded in time.

Eyeliner & Eyeliner: 3 months

Eyeliner: 1 year

Similar to mascara, liquid or gel eyeliner products are very prone to bacteria and dryness if not stored properly. In contrast, the eyeliner has a longer shelf life, but it also has a certain lifespan.

Mascara shelf life: 3-6 months

Mascara is one of the most unstable makeup products. If the scent or texture of the mascara changes, it should be discarded. In order to prevent bacterial invasion, avoid using the mascara multiple times to extract the mascara brush back and forth. The correct way is to slowly rotate it out of the bottle mouth, which can prevent excessive air from entering the bottle body, thus effectively preventing the mascara from drying out. .
