Increasing numbers of individuals suffer from one or more allergy. Well-known allergies encompass foodstuffs like seafood and cow’s milk.

DBV Technologies and Viaskin could well be the names on everybody’s lips if this new technology is as effective as tests suggest.

The Viaskin patch is a simple adhesive patch worn on the skin. The primary aspects of the patch are a titanium backing and a crown, which forms a condensation chamber with the skin.

The approach behind the Viaskin patch is relatively straightforward. A so-called ‘electrospray’ is used to spray minute quantities of an antigen onto the patch, facilitating optimal retention of its chemical properties.Unlike in an injection, the antigens are solubilized and pass directly into the body’s most tolerogenic cells, the Langerhans cells, without entering the bloodstream. This gradually ‘tones down’ the body’s reaction to these antigens.

Patch technology is especially promising in relation to pediatric allergy treatment (http://www.dbv-technologies.com/en/viaskin-products) because it does away with the use of injections.
