Don't waste your money. These do not work. I was really excited to buy them as they are meant to sort the exact spots I get - you can feel them coming for days before they surface. I have used my whole pack now and it has made no difference. I also have not been given the option to leave a review on the website which is fishy to me.

Packaging is a pain I spent not an insignificant amount of money on the combined pack and the post zit stickers, and several times have wasted expensive patches because of a design flaw in the packaging. These stickers are wired shut inside annoying plastic squares. You have to yank them open with your fingers, (which would be impossible for anyone who has issues with their hands) and frequently they fly out onto the floor, ruined and you have no choice but to throw them in the bin. It's additionally not great that you're left with a load of plastic tat after you've used one. The early zit sticker didn't work for the larger under the surface zits I had, I guess they were too stubborn. The goo getters were an interesting experience, and stopped me popping whiteheads myself. The post zit stickers did help fade marks, but it wasn't the great result I had read from others. The benefits to these are that they stop you picking and making zits worse. The cons are the expense, the ease of use and packaging.

Waste of money and too much plastic! These are an absolute waste of money, do not buy them !!! I was really excited to try them after seeing lots of positive reviews on Instagram, but they simply don’t work. The killa patches don’t get rid of any pain or deep down spots, even when left on overnight as is recommended. They also come with so much plastic, that I feel ashamed to have even purchased them thinking about all the plastic will do to the planet.

Cleared cyst in 5 days! I've started getting cystic acne and decided to give the Killa patches a go after the last cycle left my skin so incredibly painful as the cysts were so swollen and deep. Even with using actives in my skincare (AHA, BHA, PHA and retinol) it took 2 months for those cysts to go. I've since tried these patches when I saw another cyst coming up and it has taken 5 days to clear the cyst and start the healing. I used 3 killa patches in the evening and then the goo getter in the day (they were free though, i think it's better buying Cosrx ones as they're cheaper and not so obvious on your skin). I know they're expensive, but knowing just how much pain I was in last time means I'd happily pay that again. Best bet is to order when there's a sale on.

Bad company Bad company. Missed off the free gift that was the reason I bought via this company, rather than a distributor, where I would get 20% off. Avoid & buy elsewhere.
