Shelf life of skin care products, now skin care is not a patent for women, now male compatriots are also taking care of skin care, so everyone uses skin care products every day, so do you know how to calculate the shelf life of skin care products? Let's share the shelf life of skin care products with you.
The shelf life of skin care products is 1. In fact, even if you like beauty products, don't overstock them. Don't use them when they expire. Every product has a strict shelf life. The shelf life of general skin care products is 3 years. If you use expired products, skin allergies will occur. In order to ensure that it will not harm the skin, it is recommended not to use it when it is close to the shelf life. Skin is a beautiful facade, and you can't be careless.
Is the expired whitening skin care products still useful? Skillfully use expired skin care products: face cream and hand cream, and apply them on the shoe-polishing cloth to polish shoes. Refreshing alcohol emulsion can wipe dressing table, greasy tiles and range hood; Wash your face with a toothbrush, brush your collar and sleeves, and brush your sports shoes; Can be used for foot care.
Drinking tea is a hobby of many people. In fact, many ingredients contained in tea are very beneficial to skin whitening. Therefore, whitening skin with tea has become the simplest whitening method, and this method is particularly economical and practical. Whitening is often complicated and slow, so many people give up before achieving the effect.
However, when whitening with tea leaves, it only takes simple steps to whiten the skin, and it can be done when drinking tea at ordinary times, so it is easy to stick to it.
If your whitening skin care products have expired, but there is nothing to replace them, I suggest you stop using them and try the tea whitening method. Although tea whitening has no quick whitening effect, it can at least win a moment's leisure for your face.
Shelf life of skin care products 2 Shelf life of skin care products without preservatives
The shelf life of organic essence shea butter, an organic skin care product from the United States, can be divided into two types: before and after unsealing. Skin care products can be kept for three years before opening, and they need to be used within six months after opening. It can be seen that the shelf life of skin care products without preservatives is similar.
Preservative-free skin care products should pay more attention to hygiene after opening, and can only be used after cleaning fingers, so as to avoid bringing bacteria from fingers into skin care products and affecting the use effect.
Are preservative-free skin care products safer?
Although preservatives may indeed cause certain irritation and influence on the skin, skin care products may not be safer without preservatives.
Preservatives can inhibit the nutrients in skin care products from producing bacteria, leading to deterioration and corruption. If preservatives are not added or the antiseptic effect is not good, the safety of cosmetics cannot be guaranteed.
Moreover, some cosmetics advertised as preservative-free are not really preservative-free, because as long as the 5 1 preservative in the Technical Specification for Cosmetic Safety (20 15 edition) is not added, the products can be advertised as preservative-free cosmetics.
Do you know the shelf life of preservative-free skin care products? If your skin is sensitive to allergies or external stimuli, don't forget to do an allergy test before using any skin care products.
Shelf life of skin care products 3 shelf life of skin care products
The shelf life of skin care products is 3 years, and the makeup is 5 years. 3-5 years This only refers to the shelf life of cosmetics in unopened state. Once opened, whether you use it or not, the shelf life will be recalculated, which is much less than we expected. You need to check the batch online yourself. Under normal circumstances, there will be a logo on the bottle of cosmetics to remind you of the use period after opening.
Skin care category
Make-up water, cream, essence, eye cream and makeup remover should be used up within 4~6 months after opening. Some pure natural skin care products have a service life of only 3 months, such as Avene and Xinfei. Because there is no preservative in these pure natural skin care products, the service life cannot be extended.
Some eye creams will be used up within 3 months after opening, depending on the logo on the skin care products you buy. You must learn to read the Kaifeng sign. If there is no logo, it can be used within 6 months.
Of course, if you buy other similar products to use together, that is another matter. If you are using two cans of cream at the same time, you want to use them all in six months unless you wipe your feet together.
And those who like the new and hate the old, throw away the old when they buy the new, and use it when they think of it. Maybe the shelf life has expired. Girls who love to hoard goods should also be in charge. They must use up the old ones before opening new ones, and put away your curiosity.
You may think it's nothing even if it just expired. You know, every year, thousands of people use expired cosmetics to cause dermatitis, acne, hair follicle blockage and skin sensitivity. Long-term use may lead to skin lesions and cause cancer.
But many people don't want to throw away the expired skin care products, so they use it to smear their feet and hands, saying that the effect is good. I just ask, aren't your hands and feet your own skin? I really don't want to use expired cream to maintain leather goods.
Body care category
The shelf life of shampoo, conditioner and shower gel after opening is about 1 year, and that of body lotion is about 1.5 years, but I still recommend that you use it as soon as possible.
Because shampoos are all chemical ingredients, they will not cause chemical reactions in your hair after the shelf life. Expired shampoo may cause scalp sensitivity, hair deterioration, hair loss and other problems.
Expired shampoo and shower gel can be used to remove the odor of the toilet. Pour it in and wait a few minutes before flushing the toilet, and it will become fragrant immediately. It can also be used to wash plush toys, which will be very clean.
