Can skincare products be used differently in a short period of time?

A regular, qualified product within the shelf life.

Inside, to ensure the stability of the product. If the product is stable, the use effect will not be affected even when the expiration date is approaching. If the product is unstable, it should be used with caution.

If the product is stored in a harsh environment such as high temperature and exposure to the sun for a long time, it exceeds the limit value of product anti-corrosion, and there is also a risk of infection of microbial cherry blossom penetration. Generally speaking, as long as it is a regular and qualified product, the probability of microbial infection is very low in the normal environment during the shelf life, even if the expiration date is approaching, there is no need to worry.

When the skin care product is in an unopened state, it will not affect the quality of the effect when it is close to the expiration date.

In general, the shelf life of cosmetics is about 2 to 4 years without opening. The shelf life of various cosmetics varies slightly.

How to store cosmetics: keep them in a cool and dry environment at a temperature of 20-25 degrees Celsius; There is a small protective cap inside the outer cap of the cosmetic product, which can prevent air from entering and reduce the loss of active ingredients, and should not be discarded immediately after opening the bottle, and should be used for a long time; The excess part should not be put back into the bottle when used to avoid contamination; Be sure to seal the cap tightly after use; Pay attention to the ingredient description, vitamin C and vitamin E are relatively easy to oxidize, and when using cosmetics containing them, they should be used up as soon as possible; Cosmetics can be kept in the refrigerator when not in use.

Sometimes it is not necessarily useless after the expiration date, and some may be broken if the expiration date is far away, but try not to buy something close to the expiration date, which is not very safe.

Even if the product has passed the expiration date, but has not been opened, it can still be used within one year after the expiration date, but once the cosmetics are opened, even within the shelf life, they must be used up within one year.

No, the effect will be poor after the trial period.

The shelf life of cosmetics is generally about three years, but under normal circumstances, it will be used up after three months of opening, and of course, under normal conditions, it will basically be used up in one and a half to two months. It is used up within three months of opening because the cosmetics itself is sealed indiscriminately, and after opening, it will be oxidized when it comes back into contact with the air, which will affect the quality of the product to a certain extent, so it is generally recommended to use it within three months after opening it.

Whether it's expensive or cheap, it's important to choose what's right for you. And some people will also compare, like others, regardless of whether they are useful to their own ** or not, they will use some high-end skin care products, although a penny is a penny, and high-end will be better. So if it's not good, it will be replaced with some lower-grade skin care products, so in this case, will the ** state drop?

I don't think it's necessarily going down. Because of some premium skincare products, it may not be the best product for you**. Although some people use some high-end skincare products, their facial moisturizing and whitening results are better.

So, it also shows that you've chosen the right skincare product for you.
