These are great little patches for pimples, and they work great when used properly. They are basically a small patch version of hydrocolloid bandages - they suck up the gunk and keep bacteria out. Here are some tips for using them if you're finding they aren't working.

1. They work effectively on open pimples (whiteheads that have been 'popped'), not cystic acne or closed comedones. If you have a whitehead, use a sterile needle and create a little hole in the whitehead, then apply one of these patches. Within a matter of hours it sucks up the pus without you having to apply any unnecessary pressure to your skin. I like to replace them when I see they have sucked up a lot of pus, but they can be kept on for up to 24 hours or so.

2. These are best used in the day. They are small and barely noticeable. For nighttime use I would recommend getting real hydrocolloid bandages, cutting them to size and applying them. They are MUCH stickier and will not fall off. You wouldn't want to use them in the day though as they are not subtle.

3. Make sure you apply these to DRY skin. If your skin has any moisture they will peel right off.
