For body acne... no no For body acne - no impact (only tried body acne treatments from them as this is my main concern). Trial period lasted 4 months (this is pretty reasonable and generous). The combo I used was their BodyDouble. It really does seem all marketing, no impact for me.

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.

HORRIBLE HORRIBLE. NO STARS. FACE MASK GAVE ME A CHEMICAL BURN. DO NOT USE!!!

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.
