I used about 6 patches for aΩ blind pimple and whitehead that had popped.

The patch is very thin and sticks on very well. It's very similar to bandaids that have the clear adhesive. It even stayed on after I washed my face but the edges of patch had started lifting. So I changed after each face wash.

It was barely visible on my skin (I have light toned skin) except when it catches the light and shines.

Two of the times I used it, I noticed that I got a tiny whitehead under the outer part of the patch. I think maybe it was causing purging but I'm not sure. The tiny whiteheads went away very quickly.

Overall, it does a good job prevent picking at the pimple. But I really couldn't see much of an improvement or progress on the pimple itself when I tried it. Maybe it is better for a different type of pimple than I got. I wouldn't get it again and would probably try using a spot treatment that I've had more results for.
