Generally, the shelf life of unopened skincare products is three years. If opened, the shelf life is about one year, but I think it's best to use it up within three months. Because I think under normal circumstances, it can be used up three months after opening, if it is too long and it will lose its active effect or it will not have any effect directly, then it is better not to buy a new one.

Note. Actually, I don't know much about skin care products, but I can get a general idea. Like that kind of emulsion essence, if it is opened, the shelf life is about 6 to 12 months. Eye cream.

Cream, barrier cream.

and sunscreen can be used for a year after opening. The scrub can be used for one year after opening. Makeup remover, lotion and the like can be used for 6 to 12 months after opening. However, I recommend that if you open it, it's best to use it all within three months.

What is the shelf life of skincare products after opening?

Generally speaking, cosmetics such as makeup have a shelf life of about 12 months to 24 months, but cosmetics such as eyeliner have some special ingredients and only low preservatives, so the shelf life is not too long, only about 2 to 3 months. So in fact, different makeup products, their shelf life time is different.

1. Foundation: half a year to 1 year.

Once the foundation is used for a long time, it is easy to create uneven lumps when rubbed on the face, and it is very difficult to achieve the effect of evenly rubbing the foundation cream. In addition, compared to when you first bought it, the color of the foundation that has been left out for a long time will change, and the fragrance will also change.

If you notice that the application is uneven on the face, and the color and fragrance have changed from when you first bought it, it is time to change your foundation, and instead of using the old one, it is time to use the new one.

2. Lipstick: 2 years.

If you notice that your lipstick has changed color or smells strange, it means that the lipstick has deteriorated beyond its expiration date, and the lipstick should be discarded immediately and should not be used again. Lip gloss has a shorter lifespan than lipstick, and should be phased out after a maximum of 1 year, especially when the lip gloss is sticky, and it should be discarded and repurchased.

3. Mascara: 2-3 months.

Since mascara is very durable, it is not uncommon to accidentally use the same tube of mascara for 2 years, but in fact, the maximum shelf life of mascara is 3 months. This is because mascara is a liquid and is very susceptible to bacteria. At the same time, because the germs on mascara are very easy to transfer, you should try not to lend mascara to others or borrow mascara from others.

4. Eyeshadow and powder: 2 years.

Eyeshadow and powder may seem like they can be easily used for 2 years, but know that the 2-year shelf life is based on the premise that the powder brush and sponge are washed frequently. If you want to extend the shelf life of your powder and eyeshadow, it is best to wash your brushes and sponges frequently to avoid contamination of the powder by bacteria and other bacteria.

5. Nail polish: 1-2 years.

Generally speaking, unopened skincare products are mostly three years old, or a little shorter, depending on the brand's own date. Many people know this, but they often ignore the fact that we say that the expiration date is unopened. If once you open the lid and unseal it, whether it is used or not, the shelf life will be greatly reduced.

Generally, brands such as Estee Lauder and Clinique can last for 24 months, or two years, after opening, while most other brands can hold it for one year.

FANCL was the shortest without addition, only 6 months.

3. Proper storage of skincare products can help to prolong their use. The correct storage method should be to keep skin care products in a dry, cool, and unexposed place, so as to avoid skin care products deterioration caused by high temperature, low temperature, ultraviolet rays, and humidity.

4.

The shelf life of skincare products is generally based on their formulation and materials. Different types of skin care products, such as cleansers, creams, **, etc., usually have a fixed expiration date after opening. The length of the shelf life is mainly affected by factors such as the preservatives added to the product and the storage conditions.

Generally, skincare products have a shelf life of around 6 months to 3 years.

For most skincare products, their shelf life is relatively long. This is because some preservatives are generally added to skin care products to ensure that the product can remain effective and safe for a certain period of time after opening. Skincare products that have passed their expiration date may lose their potency or produce some ***, so it is recommended to check the date on the product before using it and use it as soon as possible before the expiration date.

Different types of skincare products also have different shelf lives. For example, water-based emulsions and gels typically have a shorter shelf life, typically 6 months to 1 year; On the other hand, oil-based cream products are relatively stable and can be extended to more than 2 years. Some natural and organic skincare products may have a shorter shelf life due to the absence of added preservatives, so it is recommended to use them as soon as possible.

Proper storage is also an important factor in keeping skincare products effective. Skincare products should be stored in a dry, cool, and dark environment, away from direct sunlight or high temperatures. Make sure your hands and containers are clean and hygienic before use to prevent bacterial contamination.
