To be honest, I’m not super impressed with these. I’d never tried pimple patches but I had read a lot about them and seen a lot of reviews and ways to use them. I used them on non-popped pimples, on popped pimples, on pimples that have just started to appear, on pimples where you have pierced a small hole in with a tool that has been sanitized,.. And the patch did seem to sooth the acne somewhat but other than that I did not really notice any big differences.. It’s not like the acne went away faster or was suddenly flat the next day. So not worth my money in my opinion.
