A total game changer (where were these when I was a teen?!)
Size: 72 Count (Pack of 1)
I honestly wish these had been around when I was younger! The Mighty Patch Original is hands-down the most effective way I’ve found to deal with stubborn whiteheads. Instead of picking at my skin and making things worse, I just pop one of these on at night and let it do the work while I sleep. By the morning, you can actually see the gunk it pulled out right on the patch (gross, but strangely satisfying). It significantly reduces the size and redness of the zit in just one use, and because it covers the spot, it stops me from touching it and causing more irritation. The 72-count pack is a great value and lasts quite a while. They stay put all night, even if you toss and turn, and they’re clear enough that you almost forget you’re wearing them. If you’re looking for a stress-free way to clear up your skin overnight, these are a must-have!

Works on all skin types
Size: 36 Count (Pack of 1)
What an amazing product! I'm in my 40s and still experience occasional acne. I purchased Mighty Patch, and after wearing it overnight, my blemish was noticeably cleared up by morning. I have fairly dry skin and already use quality skincare products both morning and night, so I was impressed by how well it worked. My 17-year-old son also tried one when he started getting a few breakouts, and it cleared up his blemish as well. His skin is much oilier than mine, which shows that this product can be effective for both dry and oily skin types. I’m very happy with the results and will definitely be purchasing it again!

Works as expected! Good value
Size: 36 Count (Pack of 1)
I bought these because I ran out of Curology patches that I got with the free trial. These work similarly; you’ll need one or two patches to fully get rid of the pimple— it depends on how large & inflamed it is. Even if you need two the first patch will still a do a good job of draining most the gross fluid out. I like that these are more translucent/transparent than some other brands I’ve seen. They’re not obnoxious looking if you’re wearing one or two in the daytime. The adhesion has been great so far. I’ve tried it on bare and moisturized skin and either way it holds up. Once it’s been stuck in place for a few minutes you can apply a moisturizer on your face OVER the patches without them slipping off. Just use a gentle touch. There’s probably cheaper pimple patches from smaller brands but $4.49 (before tax) is definitely a reasonable cost for 30 patches So I gave it 4 stars for value for money. My only qualm is that the small size pimple patches could stand to be at least slightly bigger. Only new closed comedones that are just forming are that small (typically). Otherwise I’m satisfied with this purchase.

The Best for Sensitive Skin & Smells Great!!
Scent: Refreshing, Size: 16 Fl Oz (Pack of 2), Scent: Refreshing, Size: 16 Fl Oz (Pack of 2)
I've purchased this body wash (Awakening) a few times now, because I love it so much! I have my whole family using it, even my child with eczema, and it's really helped her skin. It leaves our skin feeling fresh, nourished, and soft with no irritation. The liquid soap is clear and has a not-too-thick consistency. It lathers well, and I’ve had no issues with leakage. I love that it's free of so many harsh chemicals and is infused with organic and natural ingredients like aloe vera and tea tree oil. It has a wonderful earthy, invigorating scent from the camomile, geranium, and copaiba. You don't need to use much since it's a little more concentrated, and for its generous size and quality, it's worth every penny! I would highly recommend this body wash to anyone looking for a clean, refreshing, and effective body wash!

Best body wash
Scent: Lemongrass, Size: 16 Fl Oz (Pack of 1)
Lovely body wash that cleans without stripping your skin dry. Fragrance is light and not overpowering. One pump is more than enough for head to toe clean. Would recommend to anyone.
