iii. Can you explain a little more on patch test?

Patch-Testing before Use

A patch test is a painless procedure where ingredients/substances are put on your back in small dollops and kept on for a few days, with readings by your doctor at intervals like 48 and 72 hours. It can be a little costly upfront, but the amount of time, money and discomfort/skin trauma it can save you (versus random trial and error) over time makes up for that hundredfold. It tells you EXACTLY which ingredients you, in particular, need to avoid. So, for example, you may need to avoid certain dyes in clothing, certain laundry soaps, and certain metals in your cell phone, etc. but may actually be ok using such natural ingredients as tea tree oil…this helps guide you far more specifically. And if you happen to be in the USA and your dermatologist is a member of the American Contact Dermatitis Society, your patch test results can be entered into the CAMP (Contact Allergen Management Program) database…so that instead of just a list of ingredients to avoid, you get a list of brands and product names that you can use.

Not to over-emphasize a point but this is also why the VH-Rating System is so handy. If you have not yet had a patch test, choosing the highestVH-Rating (showing that zero allergens are included in the formulation) can already significantly improve your chances of non-reaction. If you HAVE had a patch test, if an allergen is included in a product, the VH-Rating will alert you to the presence of which allergen in particular is included (for example Vitamin E). If your patch test shows you’re allergic to parabens and not vitamin E, then you probably can still use the product.

Marcie Mom: Thanks so much Laura for your help in helping us understand the big picture on ingredient labeling. In our next interview, we will learn in greater detail about reading ingredients on the label.

This is part of a 13-part series focused on understanding and using products for sensitive skin, an important topic given the generous amount of moisturizers that go onto the skin of a child with eczema. Marcie Mom met Laura Verallo Rowell Bertotto, the CEO of VMVGroup, on twitter and learnt that her company is the only hypoallergenic brand that validates its hypoallergenicity. VMV Hypoallergenics is founded in 1979 by a world renowned dermatologist-dermatopathologist (Laura's mother) who also created the VH-Rating System. The only validated hypoallergenic rating system in the world, the VH-Rating System is used across all the products at VMV, significantly decreasing the risk of reactions (a study published in a leading contact dermatitis journal showed less than 0.1% of reactions in 30 years). In this interview, Laura (with VMV's founding physician) answers Marcie Mom’s questions on understanding the product label.
