Leaves face feeling clean, soft, and smooth
Love this facial cleaner. I actually double cleanse my face. First I use an oil based makeup remover, then I cleanse with this face wash. It doesn’t strip my skin of moisture, and I’ve noticed less redness on my face after switching to this cleanser. The cleanser is light and leaves my face feeling clean, soft, and smooth. I would recommend to people who notice their face feeling “tight” or noticing redness after cleansing.

Easy to use
I love these. Not only do they work at reducing any blemish size and inflammation, they are practically invisible like advertised.

Really help soothe redness and speed up healing
I've been using these patches for a while now and I'm very happy with them - they're virtually invisible on the skin, stay on well and really help soothe redness and speed up healing.

My kid loves them!
My kid loves these. They also said they like that, unlike some other ones, they can see underneath it somewhat to tell when its more ready to come off.
