Experts from Northwestern University in Chicago studied moisturizers and the ingredients. They found that 83 percent said to be hypoallergenic but had ingredients that could cause a skin reaction. Also, close to half of the products that labels said 'fragrance-free' contained an ingredient that cause a fragrance. The FDA does not barely regulates moisturizers because they are considered to be cosmetics. The researchers recommend for consumers to pay attention to the labels and be wary of all products. St Ives (left), Cetaphil (center) and NIVEA (right) were some of the products analyzed by the researchers.
