I normally use these pimple patches during that time of the month whenever I get one or two pimples. Your pimple must be popped for this to work. If you can treat the pimple before it pops, by all means treat it, but if your pimples become ripe and break open, then these pimple patches will work great! I shower in the evening so what I do is I put on the pimple patch right away once I get out. Then I apply my skin care products around the patch. You want to make sure that your zit has no products on it or else the patch will not stick. I go to bed with the patches on and then the next morning I gently peel it off. If my pimple still looks bumpy and seems to have more "junk" in it, then I apply another patch after cleaning and patting dry the area. Yes, I have worn these to work before, especially when I know I will be in the office all day.
Here are a few infographics from Cosrx explaining how to use the patches:
You can see that the patch collected a lot of gunk. Below is another look at the patch.
I have really enjoyed using these patches, and I will continue to buy them. I got my fiancé loving them as well as my sister, co-worker and cousin. It works wonders at improving and treating the affected area. Many times we like to pick at our pimples, but that can lead to scarring. I feel as though these patches help create less scarring. These are awesome, and I highly recommend them!
I have used the Nexcare Acne Absorbing Covers that you can purchase on Amazon for approximately $8, and I do not like them as much as the Cosrx ones because they do not stick as well. The Nexcare patches fall off my face when I sleep, whereas the Cosrx stays on throughout the night.
You can purchase the Cosrx Acne Pimple Master Patch for $5 online at retail price at Sokoglam and other retailers, but if you can wait between 3-5 weeks, you can order from Jolse.com and get a sheet for $3.75 instead. I normally buy the 10 sheet pack (~$2.40 per sheet) from Jolse.com since my fiancé and I like to have back-ups. Plus, it's a better deal when you buy in a bigger bulk vs buying one sheet, but it's good to just buy one if you want to try it out first.
