They get the job done, but not as well as other pimple patch options. For whatever reason they tear off a layer of my skin along with the pus it absorbed. My mom has had the same issue. Maybe it's fine if you have thicker skin.

Great Value

Game changer
These have changed the game for me. I'm a picker so spots usually last for months for me, but this flattens them down and takes a good majority of the rubbish out. This gets rid of 90% of the spot, and leaves just pigment...
