VH -76/76 = Validated Hypoallergenic MINUS all 76 of 76 allergens.
VH -75/76* = Validated Hypoallergenic minus 1 allergen (the product has 75 of 76 allergens omitted), indicated in the ingredients list by an asterisk.
Why is it important to identify the allergen in the ingredients list? Because knowing which allergen is present can help expand your product options.
For example, if your patch test shows that you are sensitive to parabens but not to dyes (which are known allergens), and a product contains a dye, it's VH-Rating would be VH-75/76*. With the asterisk, a quick glance at the ingredients would show you that the allergen isn't one that you are sensitive to, and the product should still be safe for you to use.
If you have not had a patch test and have a history of sensitivity, choose higher VH-Ratings.
NOTE: We are all individuals and you may be sensitive to an ingredient that is not yet considered an allergen. If you have a history of skin sensitivity, your best bet is to ask your doctor for a patch test.
Most VMV products are rated VH -76/76: all 76 known allergens are absent. If we must use an ingredient that appears on the allergen list, it is usually present in the smallest possible concentrations, ranked low on the allergen list, and indicated by an asterisk so that you can quickly identify if it's an ingredient that you are allergic to.
While lower VH ratings can work for many people, you can choose products with higher VH numbers if you have a history of allergies or hypersensitivity. This is the beauty of the VH-Rating System: you are empowered with a clear indication of what allergens are included/excluded, so you can make wiser decisions on what you can use.
