For most people, buying a "fragrance-free" or "hypoallergenic" moisturizer that turns out to be neither might be frustrating, but not harmful. But for people with sensitive skin or conditions like eczema or psoriasis, it can be a big problem.

"I will start to itch and I have to get it off my body right away," says 62-year-old Kathryn Walter, who lives in Ann Arbor, Mich.

Walter has a severe case of eczema and chooses moisturizers that claim to be free of fragrance and allergy-causing additives. But more often than not, Walter ends up with a product that clearly isn't.

"My ankles and calves are all scratched up as we speak — and my hands," she says.

For people like Walter, moisturizers aren't just for smoothing skin. They can actually treat the dry, cracked and reddened skin that come with conditions like eczema. But finding the right moisturizer can be truly "hit or miss," she says. "Because you can't just go to a drugstore and open up all their tubes of cream to make sure they don't aggravate your skin." So Walter ends up throwing a lot of products away.

"Basically, it's a big expense," she says.



"Every single day, I get questions about what moisturizer should I use, what sunscreen should I use," says

, a dermatologist at Northwestern's Feinberg School of Medicine.


"I found myself really struggling to provide evidence-based recommendations for my patients," he says. So he decided to take on the challenge of figuring out "what's actually in this stuff."


Xu and some of his colleagues at Northwestern examined the ingredients of the top 

 sold by Amazon, Target and Walmart. What he 

 was pretty surprising, he says. Nearly half — 45 percent — of the products in the study that claimed to be "fragrance-free" actually contained some form of fragrance. And the vast majority — 83 percent — of products labeled "hypoallergenic" contained a potentially allergenic chemical.


Bottom line: The vast majority of moisturizers that are best-sellers "have some form of potential skin allergen," Xu says.

And when a product is labeled "dermatologist-recommended," Xu says, "it doesn't mean much," because there's no way of knowing how many dermatologists are recommending it, or who they are.

"It could be three dermatologists, or a thousand," he says.



In large part, the deceptive labels result from the lack of federal regulation of these sorts of products. The Food and Drug Administration 

 and barely regulates them. There are some labeling requirements, but they can be easily avoided by companies that claim the ingredients are "trade secrets," says 

, vice chancellor for Health Data Science at Duke University School of Medicine and a former FDA commissioner.


"The cosmetics industry is highly competitive," Califf says, "and if someone can easily copy someone else's successful cosmetic, that would be a competitive disadvantage."

And when it comes to adverse reactions, manufacturers aren't required to report consumer complaints about cosmetics. This means the FDA doesn't know the extent of the problem, says Califf.

"I don't think it's too much to ask of manufacturers that they [be required to] register what they're selling so that it can be tracked," he says.

 accompanying Xu's study; both were published in a recent issue of 

 that could make the industry more accountable. In the meantime, dermatologist Xu recommends what he calls a "skinny, skin-diet."


"What we mean is, using the least amount of products with the least amount of potentially allergenic materials or chemicals in them," he says, "to reduce the risk."


Xu says some single-ingredient products — like petroleum jelly, shea butter, sunflower oil or cocoa butter — can minimize the risk of an allergic skin reaction.  Copyright 2019 NPR. To see more, visit https://www.npr.org.
