The Magic Makeup Eraser is a cloth that claims to take off your makeup with just water – No cleansers, no chemicals. According to the official website, the cloth is made from specially knitted polyester and silk fiber contains millions of tiny hair-like fibers (each fiber is 50-100x thinner than a human hair) that works as a “suction” to lift all dirt, makeup, and oil from each individual pore.
So how does the magic makeup eraser work? Friction. To lift the make-up from the skin, the fibers need to grip onto the make-up and pull it off. The greater the surface area, the more grip, and friction each wipe will have without you having to push down so hard.
If there’s enough friction, the make-up will lift off the skin, but then it’ll just be smeared around unless the cloth can grab onto it. Luckily, at a molecular level, everything is quite sticky with adhesive forces (the technical term is van der Waals forces). Because there are so many fibers, these cloths can bind to dirt and hold it better than a normal cloth.
The magic makeup eraser is like a washable face wipe than can remove makeup with just water. Simply put, the fibers when wet create a hydro-mechanical process that breaks down the surface tension of the oils that bond makeup to your skin.
It works reasonably well, especially on the go when you don’t want to pack a bunch of stuff.
