Be wary of ‘for eczema’ claims on labels of popular moisturizers
Be wary of “for eczema” advertising claims contained on the labels of popular skin moisturizers.

“Prescription medications are important for managing eczema flares, but a lot of the work in treating eczema is preventative, done by consistently moisturizing the skin at home with drug store products,” co-first study author Catherine L. Ludwig, said in an interview. “Allergic contact dermatitis occurs more commonly in people with eczema. A previous study was done in characterizing the allergenic potential of drug store moisturizers and found that 88% of moisturizers contain at least one common allergen. Many moisturizers are marketed specifically to eczema, but the allergen content of these products are unknown.”
For the current study, Ms. Ludwig, a medical student at the University of Illinois at Chicago and co-first author Alyssa M. Thompson, a medical student at the University of Arizona, Tucson, and their colleagues compiled a list of the top 30 moisturizers “for eczema” sold by Amazon, Target, and Walmart. For each moisturizer they recorded common ingredients and marketing claims related to benefits for atopic dermatitis, including eczema relief, sensitive/gentle skin, hypoallergenic, anti-itch, anti-inflammatory, clinically proven, oatmeal, dermatologist recommended/approved, organic, fragrance-free, for baby, or National Eczema Association approved. To establish allergenic potential, the researchers used MATLAB to compare ingredient lists to compounds listed as common allergens in the American Contact Dermatitis Society’s Contact Allergen Management Program database (ACDS CAMP). Next, they used the Mann-Whitney U test to evaluate differences in allergen count between products with and without specific marketing claims.
Ms. Ludwig and her associates found that 28 of 30 products analyzed (93%) contained at least one allergen, with an overall average allergen count of 3.60. The three most prevalent allergens were cetyl alcohol (70%), phenoxyethanol (50%), and aloe (33%). “Anti-inflammatory” moisturizers had the greatest average number of allergens (4.00), followed by “anti-itch” (3.71) and “oatmeal” (3.71). Only products claiming to be “hypoallergenic” had significantly lower allergenic ingredient count (an average of 2.45) than those without the claim (P = .011).
“It was validating to see that eczema moisturizer products marketed as ‘hypoallergenic’ truly do have fewer allergenic ingredients than moisturizers without the claim,” Ms. Ludwig said. “However, it was surprising to see that even products marketed to eczema patients, who have a higher prevalence of allergic contact dermatitis, contain an average of 3.6 common allergens. As dermatology providers, we can relay to patients and parents that relying solely on ‘for eczema’ claims is not advisable. Clinicians should acquaint themselves with the top allergens (cetyl alcohol, phenoxyethanol, and aloe) and keep these ingredients, as well as affordability and patient preferences, in mind when making product recommendations.”
