⭐️⭐️⭐️⭐️⭐️ PanOxyl has really helped improve my skin! It deeply cleans my pores, helps reduce breakouts, and leaves my skin feeling fresh and smooth. I also noticed my acne started calming down after consistent use. Great product for acne-prone skin! 💕

Omg
Size: 3 Ounce (Pack of 1), Size: 3 Ounce (Pack of 1)
Oh. My. Goodness. I had pretty bad acne. one day at a store I bought a travel size of one of these 10% panoxyl and tried it and omg my pimples are gone. Yes I get the occasional spots but they aren’t as terrible as before. My face is so much clearer and it even cleared a little spot of milia I had for so long! My face feels fresh everytime I use it and looks shiny and healthy. No burning for my face atleast. Doesn’t bleach if you rinse it off well. My routine is face wash, panoxyl, azelaic acid, moisturizer. Pretty simple I don’t follow influencers bc they make you buy all this junk products you don’t need for your face and for me less is better. The idea is that benzoyl peroxide essentially kills the bacteria that causes acne on your face. It works so well. I would recommend if you’re gonna use this to patch test on a part of skin near your face could be your temple area by your ear but it’s so important so you don’t end up with burning skin if your sensitive. But otherwise it’s so great and I love it I use it everyday with occasional 1-2 day breaks cleared my acne and now my face is getting more clear! So happy I got this.

An Absolute NEED In My Skincare Routine!!
Pattern Name: 50 count (1 pack of 50 ct), Pattern Name: 50 count (1 pack of 50 ct)
These are an absolute need in my skincare routine! I use them to remove oil-based and water-based cleansers and to remove masks. And I use them to dry my face and then to dry my hands in between products. They are very good quality and very soft. They are also thick and very durable. They have a smoother side and a textured side for very gentle exfoliation. I notice my face is more clear from using these as opposed to my microfiber washcloths. They’re fragrance-free and don’t really have a scent, maybe a very light, practically unnoticeable, bamboo scent. I think it’s a very good deal to get 50 XL disposable face towels for $17. I was using these for months and then didn’t use them for a few months and yeah huge difference in my skin, which is why I bought them again and will continue to. It’s also great not having to wash them lol! I also love the new magnetic lid closure and the new design of the box, you can now have your face towels fully covered and sealed without having to buy a separate box with lid to put them in. Although their prism holographic box is so cute and pretty, and their prism box is $20 cheaper on Amazon!

Great quality face cloths with a soft exfoliating texture to them.
Pattern Name: 50 count (1 pack of 50 ct)
Absolutely love these towels. So nice to have a clean towel every time you wash your face. They are the perfect texture for lightly exfoliating. These are just dry towels so you can use your own face wash with them. They are very durable. I tried ripping one in half once and was unable to. They are quite large and I have found that I can have twice as many by cutting them in half. They are still a great size after cutting them. I can definitely see why they are so highly rated. I definitely wasn't holding my breath with high hopes but after using them I am pleasantly surprised! They are quite reasonably priced especially if you cut them in half and if you subscribe to them for additional savings. Very surprised how much I love them!

SOOOO GOOD
Pattern Name: 50 count (1 pack of 50 ct)
I finally caved and bought these. I wish I would have hoped on this trend when it was first talked about in the skincare community because they are SO good, soft but also exfoliating, no scent, perfect for your face or anything else you want to clean. I did get the XL size without noticing but I’ll be buying these regularly. It makes doing my skincare at night so much easier.
