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 behind. It's not 100% healed but speeds the process up by about 2 weeks

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.
