I am so glad I found these makeup wipes! I have extremely sensitive skin and have never been able to use makeup wipes because they irritated my skin. These don’t do that at all!! I love how moisturizing, but non-greasy these are. They take my waterproof mascara off with really easily!! Will definitely be repurchasing!

Excellent product, Excellent service

I had difficulty finding this item in stores. It's new packaging and new formulation. I love the wipes, and when I ordered them they came two early in pristine condition.

My favorite facial wipe

Scent: Aloe Vera, Size: 25 Count (Pack of 4)

I purchased these facial wipes through Amazon because I could not find them locally. I prefer these to another brand. These work very well and they do not irritate my sensitive skin.
