TOPLINE: 

Many over-the-counter vaginal and vulvar moisturizers contained contact allergens, and several marketing claims such as "hypoallergenic" and "fragrance-free" were not supported by their ingredient lists, according to a review of 66 products.

METHODOLOGY:

Researchers conducted a cross-sectional analysis of 66 commercially available vulvar and vaginal moisturizers marketed for vulvovaginal dryness or intimate care from five major US online retailers (Amazon, CVS, Walgreens, Target, and Walmart) between January and March 2026.

• Ingredient lists were standardized and compared with the North American Contact Dermatitis Group (NACDG) 80 (NAC-80) screening series and the American Contact Dermatitis Society ( ACDS) Core Allergen Series to identify potential contact allergens.
• Researchers recorded vehicle type, consumer ratings, and marketing claims (such as "fragrance-free" and "hypoallergenic") and verified against actual ingredient composition.

TAKEAWAY:

Overall, 77.3% of products contained at least one ACDS allergen and 66.7% contained at least one NAC-80 allergen, with a mean of 1.38 ACDS allergens and 0.98 NAC-80 allergens per product.

• Tocopherol, sodium benzoate, and cetyl stearyl alcohol derivatives were the most common allergens, with tocopherol present in a substantial proportion of products.
• Half of the products were labeled "fragrance-free," but 24.2% contained fragrance-related ingredients, and among products labeled 'hypoallergenic," only 28.6% met the study criteria for that claim.
• Humectants were present in 62.1% of products, while emollients, present in 18.2% of products and occlusives in 13.6%, were less common. And 25.8% of products contained no recognized humectants, emollients, or occlusives.

IN PRACTICE:

"The high prevalence of contact allergens, combined with inconsistent claim accuracy, poses challenges for patients seeking low irritant and low allergenic options," the authors wrote. "Clinicians should prioritize allergen avoidance and ingredient-based selection over marketing terminology, and improved labeling standardization would support safer consumer choices," they added.

The study was led by Hamna Khalid, BS, of the Carle Illinois College of Medicine, University of Illinois Urbana-Champaign in Urbana, Illinois, and was published online as a brief report on June 8 in the Journal of the American Academy of Dermatology.

LIMITATIONS:

Exclusion of 12 products due to incomplete ingredient data could have affected the comprehensiveness of the analysis. The cross-sectional design and inclusion of products available from only five US online retailers over a 3-month period potentially limited generalizability to other markets or time periods. 

DISCLOSURES:

The study did not receive any specific funding. The authors disclosed no relevant conflicts of interest.
