These are the best pimple patches I've tried. They stick well, suck out all the gunk, flatten and reduce redness overnight. They prevent me from picking at my skin and the results are so satisfying. I've applied them to tiny pimples, which sometimes completely disappear over a one time use. For bigger ones it can take longer to heal, but there's always a huge difference before and after. Also pretty good amount you get compared to other brands (51pcs). Have repurchased so many times already.
