Labels refer to such notices as texts, symbols, numbers, patterns, etc. on the product sales packaging used to identify the basic information, 

attributes and safety warnings, as well as packaging containers, boxes and instructions with identification information.

Consumers can get some necessary information from the product labels, which are usually mandatory for the protection of consumers' rights and interests, mainly including the following:
? the Chinese name and special cosmetic registration certificate number of the product
? the names and addresses of the registrant and the filer; where the registrant or the filer is an overseas enterprise, the name and address of domestic responsible person shall be marked at the same time;
? the name and address of the manufacturer, and domestic cosmetics shall also be marked with the manufacturer's production license number
? the number of product standard
? the full ingredients
? the net content
? the use period
? the method of use
? the necessary safety warnings
? other content required to be marked by laws, administrative regulations and mandatory national standards

Consumers can also learn about some of a product's promotional information from the product label, which usually includes the product's features, efficacy, target groups, main ingredients, etc.

Consumers can learn about the specific ingredients and their approximate amounts from the ingredient information on product labels. Regulations of different countries have varied legal provisions and requirements for the identification of ingredients. For example, China's Measures for Administration of Cosmetic Labels stipulates that cosmetic labels shall be marked on the visible side of the sales package with the standard Chinese names of all ingredients of the cosmetic with "ingredients" as the introductory word, and in descending order of the content of each ingredient in the product formula. Where cosmetic formulations contain ingredients with a content not exceeding 0.1% (w/w), all such ingredients shall be separately marked with "other trace ingredients" as a guide, but they don't have to be listed in descending order of ingredient content.

In this way, consumers can choose products based on their own needs and desires, especially those who are "ingredients-oriented" and pay special attention to the ingredient information of the products. Consumers tend to believe that the more ingredients that are present, the better the product is, but this is actually not the case. Each ingredient has its own efficacy and safety limits, and a blind pursuit of high additive levels may cause safety issues.
