First aid for pimples

Hi! Half a year ago I received a sample from Blositive. It was patches for your pimples. I was excited, but I had to wait (fortunately) a long time testing. The patches work fantastically on a white-headed pimple. It must sit on it for at least six hours and then my white head was gone. What shouldn't you do! The patches stick to a pimple without a white head. After six o'clock, I did the patch off my face, but it left a very red spot. Later the pimple became a scar. It's not very nice to walk like that. Great product, but thinks it's pricey. What are your experiences with patches like this? X
