To the Editor We read with great interest the article by Xu et al1 published in a recent issue of JAMA Dermatology highlighting the high prevalence of contact allergens in common moisturizers. Their data mirror similar results in our recent study2 investigating contact allergens in pediatric personal care products marketed as hypoallergenic, dermatologist recommended and/or tested, fragrance free, or paraben free.2 Similar to the study by Xu et al,1 which found that 88% of common moisturizers contained at least 1 common contact allergen, we found that 167 of 187 of our selection of pediatric products (89%) contained at least 1 allergen.
