Everything about them was said, those are magical little patches that can save your face by making the pimple smaller and less red. 

I am choosing this over products like Mario Badescu's Drying Lotion and it comes close to my all-time favourite Face Shop's Anti Trouble Blemish Patch (Somaderm Spot) - which is difficult for me to get my hands on. It works marvellously, isn't as obvious as most patches (nor does it look as yucky when it extracts the dirt - which is a plus! if you wanna wear it out).

These patches are miracle workers. They come in a variety of sizes and adhere really well to the skin. You could easily wear them under makeup, though I prefer to just wear them overnight.
