Hello. I have now peeled off the 3rd patch and dirt has accumulated around it as always. The plaster adhered well to the skin, but when I pryed it with my finger, e.g. on the corner where there is dirt, I pryed it with my finger at a distance of 2-3 mm, but it held very well on its own, all the time, only in some places, where there is dirt in this photo with the plaster removed, also when I pryed it off with my finger, the edge rose slightly. It seems to me that just where the dirt has settled around, the glue sticks well, but a little less and I wonder if if the whole patch adhered firmly and properly, but in some places around, where there is dirt, I pryed this edge with my finger and it rose to 1-2mm, which is the distance at which the dirt settled. And did such a thing affect the effectiveness of the patch? I will add that I am perfectly punctual in changing the patch from the beginning of use.
