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.

A winner with our GSD. He’s not a super aggressive chewer but it has still held up and is a favorite.

Terrific toy for heavy chewers
Size: 6 in, Color: Blue
My dog loves this! Chews and plays with it constantly. These will last a long time, however, eventually they begin to break down. THEN GET ANOTHER, lasted a couple months with constant chewing.
