Dry skin+ psoriasis friendly
My partner has dry skins and psoriasis and this is his go to face wash. When he runs out he grumbles about having to use mine. Makes his face feel clean without over drying or agitating it.

Amazing Gentle and Acne-safe Cleanser!
This gentle yet effective cleanser is great for daily use!
This product is very safe for sensitive, acne-prone, and fungal-prone skin, as there are no comedogenic ingredients and fragrance-free.
When applying and emulsifying the cleanser, it transforms from a gel to a foam-like consistency, which helps remove sweat, dirt, and sunscreen from the face.

Great simple gentle cleanser
Love this cleanser. I use it night for after oil cleansing. I have oily, dehydrated mature skin. I have roseca on my cheeks so I have to be careful of harsher cleansers. I wanted just a simple hydrating cleanser. Since I have oily skin, I need a gel cleanser for the evening & this fit the bill. Doesn't strip my face, but doesn't leave any residue like so many hydrating cleansers do. It doesn't irritate my roseca & doesn't break me out. I have also used this as a morning cleanser while traveling & it doesn't disappoint. I have a different morning cleanser that is more creamy, but isn't enough at night. I'm going on my 3rd tube & will continue to buy! I would say if you have dry skin, this may not be suited for you because it is a gel cleanser.

Great product with unexpected results and skincare benefits
Size: 25 Count (Pack of 1)
I have been reading about Micellar water products for a couple of years, and finally purchased these wipes to try. I am currently working very long hours and the selling point for these wipes was that they weren't soap-based, and didn't require a toner after using. I keep them on my night stand and take my makeup off with them prior to going to bed. (I do not use them for removing mascara - I use another product for that.)
The biggest point I want to share is that I have been using these wipes exclusively for makeup removal for a little more than two weeks. I have had a stubborn blackhead on my nose for a good 20 years that wouldn't budge, no matter how often I used exfoliating products, and I've invested a lot of money in high end exfoliators in an attempt to make that spot go away. It has grown larger over the years, and was a skincare peeve of mine. I noticed a couple of days ago that that blackhead is beginning to break down and get smaller. I thought at first that I was imagining it, but that blackhead is honestly a good two-thirds gone. This is just from using these wipes! I would never have predicted that something this simple and quite soft and insubstantial as a disposable face wipe would have such effective results for blackhead breakdown, but they're doing the trick. I have noticed smaller blackheads on my chin area are also melting away. I predict that in another few weeks of use, my skin is going to be as close to blackhead-free as it is humanly possible to achieve. (For the record, I don't have a lot of blackheads - just a handful that have taken up residence over the years and refused to budge, getting larger with age.)
These are safe for my sensitive skin, and have exfoliating benefits that I wouldn't ever have expected or predicted. Full disclosure: I do spend a good 3-5 minutes using a single wipe on my face, neck, and décolletage, scrubbing with the nubby side (there is a nubby, exfoliating side, and smooth side to each wipe) and using the whole cloth in sections until I have used it all. Finally, I also use it on the tops of my hands. I definitely get my money's worth out of each wipe! I wholeheartedly encourage people to try this product. I now have it on Auto-Ship status, as I don't want to ever be without these wipes in my skincare arsenal.
