Which brands do you think are the worst offenders?

In a recent study by consumer advocacy group Better Markets, the consumer group found that more than 90% of cosmetics brands surveyed did not disclose ingredients that are harmful to consumers. 

According to a Bloomberg report, a survey of 4,100 cosmetic and beauty products conducted by the company found that the majority of products were not required to disclose the ingredients that could lead to serious health risks. 

The survey found that, of the companies surveyed, only 6% were required to provide information about the ingredients and/or toxicants that could cause cancer or birth defects. 

Among the products surveyed, 78% of the products were labeled as “essential” for the purpose of maintaining or preventing the development of birth defects or cancer, but only 10% provided that information to consumers when they purchase their products. 

For many consumers, it’s impossible to know exactly what the ingredients are in cosmetics that they purchase. 

A survey of 1,000 American consumers found that 89% of respondents said they did not know which brands contained the same or similar ingredients that were used in cosmetics. 

While it’s unclear if consumers would ever know what ingredients are harmful or if they could be harmed, consumers are more likely to be more concerned if a product is labeled as essential than a product labeled as nonessential.
