I used up 432 patches package and started new, same size package. The patches go fast! I use this patch on pimples, insect bites, swollen bumps pretty much anywhere on my face and body. In just 8 hours, while you are sleeping, the patch dries out pimple, sucks out "yuky yellow something " under insect bites, speeds up heeling process. Works like Polysporin treatment under bandage and more. Skin must be cleansed and dried out prior to patch application. I wish these patches were cheaper-that is why i buy them in bulk.
