What Is The Validated Hypoallergenic Rating System (VH-Rating System)?

“Hypoallergenic” can be an ambiguous term. It is regulated in some FDAs, but not all. When regulated, certain evidence is normally required to justify the claim but requirements can differ. Our founding dermatologist-dermatopathologist wanted a more objective, consistent, and clear way to prove what “hypoallergenic” meant in formulations.

VMV Hypoallergenics was the first to validate what it meant by “hypoallergenic” for its products with a “grading” system: the VALIDATED HYPOALLERGENIC RATING System, or VH-Rating System, created in the late 1980s (VMV was founded in 1979).

What Is The VH-Rating System?

It works a bit like an SPF in that it is a clear, immediately visible “grade” given to a formulation. While an SPF shows the product’s tested protection factor against UVB rays, the VH-Number shows how many top contact allergens are NOT in a formulation. In both cases, the higher the number, the better the “grade.”

The VH-Rating System uses published contact allergen lists of the North American Contact Dermatitis Group and European Surveillance System on Contact Allergies — based on thousands of patch tests conducted in multiple countries — as independent references.

The VH-Rating System was the first and is still the only hypoallergenic rating system in the world. A study on it published in Dermatitis, the journal of the American Contact Dermatitis Society, concludes:

“The VH Rating System is shown to objectively validated the hypoallergenics cosmetics claim.”

The same study shows that VMV products had less than 0.1% reactions reported in over 30 years.

Very simply, the higher the number, the more allergens are NOT in the formulation.

Every product has a VH-Rating on its label followed by a slash and the total number of current top contact allergens. The higher the VH-Rating, the more allergens are not included in the formulation.

In case an allergen is present, the VH-Rating will be lower than the total number of current top contact allergens. An asterisk will also be seen that corresponds to the allergen in the ingredient list (which will also be underlined) for quick identification.

Breaking Down the Elements

  • VH stands for Validated Hypoallergenic.
    • The product has been tested specifically for hypoallergenicity.
    • At VMV, this includes patch testing each raw material, ingredient, applicator, and final formulation.
  • -# (the minus sign followed by a number)
    • Shows how many allergens are ABSENT from the formulation.
  • /# (slash followed by a number)
    • Means “over this current total of top allergens.”
    • This shows the total count of the current top allergens.

A VH-Rating of VH-109/109 would be read as: “Validated Hypoallergenic MINUS 109 over 109.”

A rating of VH-108*/109 would be read as “Validated Hypoallergenic MINUS 108 over 109.” The asterisk alerts you to check the ingredients list for its counterpart, which would be the allergen present in the formulation.

Examples of VH-Ratings on products:

VH -109/109

The highest (current) VH-Rating: VH-109/109
  • Validated Hypoallergenic minus all 109 common allergens.

VH -108*/109

A lower VH-Rating: VH-108/109. Note the asterisk.
The asterisk from the VH-Rating corresponds to the present allergen in the Ingredients List … which is also underlined so you can’t miss it! If it’s not one of your allergens, you can still use the product.
  • Validated Hypoallergenic minus 108 of 109 allergens.
  • Allergens present in the formulation are identified with an asterisk and underlined in the ingredients list.
  • In this example, if you’re allergic to parabens, fragrance, or dyes but not to vitamin E (a great antioxidant), you can still use this oil-free moisturizer.

Where to get a patch test?

  • In the USA: search contactderm.org. You can search by zip code and members of the American Contact Dermatitis Society also use CAMP (the Contact Allergen Management Program) to show you not just the ingredients and substances you need to avoid but brands and products that you can use (where you’ll see VMV Hypoallergenics a lot!)
  • In the Philippines: PM VMV Skin Research Centre + Clinics, where patch testing is a specialty.
  • In other countries: ask your official dermatological society about local contact dermatitis experts who offer patch testing.

Haven’t had a patch test but have a history of very sensitive skin? Choose products with the highest VH-Rating!
