I do not really know ...

Through the patch is created due to the cushioning immediate relief of pressure pain that Hühneraugenpflaster stick very well. Even after showering the pavement stops by the second day. After that you should stick a new according to the description anyway.
The desired effect is not with me a hundred percent. Although the skin softens and dissolves, but the "softened cornea pins" (see description) can be removed at least not with me after four days. After four days of application, a reduction of the corn can be seen, but not a complete elimination thereof.

I'll try a new approach and use the patch longer, then change my rating depending on the outcome.

A word about the price: Why some partying the super low price here, I can not say. When drugstore with two large letters the paving cost 2.45 EUR.
