Work great but expensive and too much packaging I usually use the cheap corsrx patches which work great except for under the skin spots. I get cystic acne once a month due to flea allergies and these worked really well on them, the patch is comfortable and easy to put on and remove. It was difficult justifying the price however as you only get 8 and I felt like I was paying mostly for the packaging which although professional looking, felt a little wasteful as each patch was individually encased in plastic and a wrapper, I decided to try a cheaper brand on amazon but they didn't work at all and left a horrible residue so although I feel these are overpriced there doesn't seem to be many alternatives that can compete with these. I do wish the company would consider lowering the price or add more patches.

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.

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.

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.

You can never escape... Products work okay but are overpriced. Their plastic packaging feels cheap. Their marketing emails are spammy (contradictory to what they say) and there is no getting away... I've removed myself from their marketing email list 5 times only to receive 2-4 emails a day... if they can't process my email address and remove it, I fear for my card details and their infosec policies...
