Correct understanding of the shelf life of cosmetic processing

Many people should know that cosmetics must be used during the shelf life of cosmetics, otherwise it is easy to cause damage to existing beautiful skin. But do you know? The shelf life of the cosmetics on the product packaging we see refers to the shelf life of unopened storage. The skin care products after opening are basically not as long as the shelf life.

So, how long can the cosmetics last after opening? For your beautiful and tender skin, you are advised to be patient with this cheat.

Here I would like to remind you that the 6-month or 12-month period after the opening of each cosmetic is the best use period.

Cosmetics shelf life

Eyeliner: 10 months - 1 year

The liquid eyeliner can only last for ten months to a year, while the wooden eyeliner has a shelf life of 1-2 years. Honey friends can cut it continuously, so it is not as easy to breed bacteria as an eyeliner.

Mascara: 3-6 months

The act of adding liquid to the mascara after drying is a versatile girlfriend who is very dissatisfied. If the volatile ingredients are accidentally entered into the eyes, the damage is extremely great. We kept using the mascara brush to let the air enter the paste tube, and at the same time let many bacteria sneak into it.

Powder cosmetics such as blush and eye shadow: 1-2 years

Powder cosmetics last longer than liquid cosmetics, but they should be checked regularly. If any of its status, color and taste have changed, throw it away!

Basic isolation: 1-2 years

Filling isolation can be stored for up to 1 year, while a pump can be stored for 2 years.

Lipstick: 1 year

The change in color, texture and scent is a warning sign that the lipstick has expired. If your lipstick looks the same as usual, all you have to do is wipe it clean.

Liquid foundation: 1-2 years

If the texture becomes thick, the oil is separated, discolored, or smelly, it must be replaced.

Skin care product shelf life

Skin care products have a "one-year law" that Kaifeng skin care products should basically be used up within one year.

Anti-aging products: 1 year

If it contains VC, vitamin A acid and other ingredients will be thrown away for more than 6 months.

Acne, anti-acne products: 1 year

If it is a acne product containing benzoic acid, it will be invalid after 3 months of opening.

Sunscreen: it is best to run out of the year

It can be stored for 2-3 years without opening, and the sun protection value will decrease with time after opening.

Cream: 1 year

If the cream bottle is open, bacteria will be introduced when the cream is taken with your fingers, so use it within 3-6 months. In the case of a squeezed mouth package, the period of use can be extended to 12 months, but it must be ensured that the seal is good.

Milky emulsion: 1 year

The deterioration of the watery emulsion will be faster, so once the odor is present, it means that the freshness is no longer. The body milk of the pressure bottle has a shelf life of 2 years.

Eye cream: 1 year

If there is oil separation or odor, it may mean that the oil in the eye cream has deteriorated and should be abandoned as soon as possible.

Natural products: 3-6 months

Think of natural phenomena, natural products without preservatives are like food. If you put them in the refrigerator, the quality will be longer, but the natural things will change faster.
