Disappointing results and poor adhesion.
I love Hydrocolloid pimple patches. I have used at least half of the brands available for sale and even the non brand ones. I’ve also used the hydrocolloid sheets and cut them to size and the hydrocolloid gel bandaids and used for pimple patches. I love how they help along the healing and keep me from picking at the pimple. This brand I wasn’t impressed by. None of them stayed on my face for half the night. The one that remained in place the longest out of the 4, didn’t show any signs of improvement. The longest they kept in place was 3 hours. I had to reapply and I still handbrake noticed any signs of healing after using one full sheet on 4 smaller sized blemishes because the adhesive wasn’t working.

Stops Me From Picking and Actually Works
As a woman in my 40s, I never would have guessed I’d still need pimple patches, yet the occasional zit still pops up — and these things are like magic. They work really well, blend into my fair/light skin nicely, and are barely noticeable at a quick glance. I’m also a terrible picker, and picking is so bad for your skin, so I love that these keep me from messing with pimples while doing all the work for me overnight. I’m always grossly fascinated by how much gunk they pull out by morning. Very happy to have these in my little skincare emergency arsenal.

Camouflages well with the skin and sticks long enough
I was excited to try these Halo Dot patches because I was having some breakouts before a wedding I had to attend. I put these on three nights before the wedding only at nights and left them on until the morning. I washed my face the 1st night, yet the second night I did not and it still attached (mind that I have a very oily face by the end of the day). With every application I saw good results as the breakouts were being reduced with each use. It is easy to put on and to carry out if you need to travel because it comes in two separate little envelope like package that you can put in a backpack/purse. These are thin and are almost not visible.

Easy to Use and Surprisingly Effective
Even though I am well past the age when I thought breakouts would stop happening, I still get the occasional pimple. As luck would have it, I felt one starting to pop up on my cheek the day after these Halo Dot Pimple Patches arrived. Before bed, after washing and thoroughly drying my face, I applied one of the patches. It peeled easily from the backing sheet, and when I realized I had not placed it quite right, I was pleasantly surprised that I could lift and reposition it without any trouble. What really impressed me was how well it blended into my skin. I was only wearing it overnight, but honestly, I do not think anyone would have noticed it unless they were looking very closely. In fact, I forgot I even had it on until I looked in the mirror the next morning. The patch peeled off easily and had clearly pulled some of the buildup from the blemish overnight. There was no redness or irritation afterward, and the spot looked dramatically improved by morning. The only downside for me is the price, especially since the package contains just 33 patches. That said, if they continue to work this well, I would definitely consider purchasing them again.

Love these already! Came in handy just when I need it!
These acne patches came in really handy when I had a random breakout near my lip, especially since that’s an area where I tend to wear a lot of makeup. They helped gently draw out impurities without being harsh on my skin. I also like that they blend in well on the skin. They’re not tinted, but they still work nicely across different skin tones like advertised, which makes them less noticeable while wearing them. You get a good amount in the package as well—33 patches total, with 18 patches on each sheet. Overall, they’re convenient to have on hand for unexpected breakouts, and I would definitely recommend them.
