I mainly use this just for my scabs and scars from acne. It sucks out all the liquid and dries and quickens the healing process. However, this doesn't work on my pus filled pimples. The next morning, I pull is off and its still there. $4USD Is a tad bit pricey, especially when buying from Australia. To fix this issue, I cut up each patch to fit my actual pimple to get my bang for my buck. But still, it'd be great if it is more cheaper!
