It´s a set of patches to dry spots (it seems like the herpes adhesives).
The e patches doesn`t make miracles, but I notice that they accelerate the drying process of the spots.
I think that their effectiveness varies with the size of the spots. When they are small / medium, I use it overnight and in the next morning the spot is more "wimpy" and begins to dry faster.
But I had two large bubbles (horrible!) and I used the paches in two nights, and the spot size decreased only a little bit, took longer to dry and the redness was still there.
On a scale of 1 to 10 points, I give them 8 points.
