-The secrets of the shelf life, place of origin and production date after opening are all in it.
The shelf life of general skin care products refers to the "shelf life of products before opening". After opening the bottle, use it according to the shelf life after opening the bottle. If a skin care product has not been used up for a year or two, it is really unfair to accuse the product of being ineffective. In fact, people have already passed the best use period. How can the active ingredient be effective when it is oxidized and deteriorated? Generally, a small can icon with numbers on it can be found on the back of skin care bottles in Europe and America. If you can't find this small mark on the bottle, it may be that the product origin has not promoted the Kaifeng shelf life labeling system, but in any case, it is not a bad thing to use it as soon as possible.
In addition, the certification mark, bar code and batch number mark on the bottle can not be ignored. They represent that the products follow strict standards from production to factory, and at the same time, you can know the origin and production date of the products.
Exclusive identification is very important.
-Patented technology and exclusive ingredients wish you a better skin care.
Nowadays, many products will also print exclusive patented ingredients, technologies or low-sensitivity tests on bottles as the exclusive logo of the products, so that consumers can see the ingredients of the products at a glance, which is naturally safer for the skin.
Small cans are marked with words such as "6M" and "12M" on the icon, indicating that they should be used within 6 months or 12 months after opening. Generally, the service life of skin care products is different after opening, and the product without preservatives and spices has a shorter validity period.
The prefix code of skin care bar code is generally used to identify the country or region of production, and it will tell you where these products come from! For example, prefixes 30-37 indicate that the product is produced in France, prefixes 45-49 indicate that it is produced in Japan, and prefix 880 indicates that it is produced in Korea. However, some brands will also choose to import raw materials from the country of origin and repackage them in China. Prefixes 690-693 mean that they are produced or repackaged in China.
The black-and-white arrow mark indicates that the packaging of the product meets the environmental protection requirements, that is, it meets the ecological balance and environmental protection requirements from production to use to final recycling.
This sign with an arrow indicates that skin care products or their packaging are made of renewable materials, which are generally recyclable and recyclable goods. The symbols of different countries will be different. Most of the producing areas in Europe and America are triangles, while those in Japan and South Korea are squares, but they are all circles with arrows.
The EU organic certified skin care products should achieve the following goals: 65,438+000% of the raw materials meet the relevant reference indicators of the EU and Ecocert, more than 95% of the total ingredients are from organic plants, and more than 65,438+00% of the total ingredients (including water) are from organic plants.
