I bought this during an itch induced madness. I was up all night scratching not one, not two, not even three hour FOUR mosquito bites. They were the worst I’ve ever had. I knew this couldn’t help those bites but ya girl was scared for future bites. So I bought it. Arrived fast. Just in time for two more bites. I’m attaching two photos. The ones with scary scans are from not using it. Idk if you can even tell on the other photo where the bite was!! Night and day difference. I forgot I had been bitten there. You do have to repeatedly use it — I used it on each bite 3-4 times for 30 seconds each. Obviously to me this is a minor inconvenience compared to such SWIFT relief! No scabs, no more itching. I keep it in my bedside table and would consider buying more just to have around. Thank you bug bite thing!!!
