Gets make up off easily!
Size: 50 Count (Pack of 1)
The take off makeup really well! I cannot believe how much makeup it takes off. My Climate makeup last and this takes it off. I was using wiped and not doing extra cleaning. My face feels awful in the morning. Using these and cleanser and my face feel good when I wake up.

Best Makeup Remover!
Size: 50 Count (Pack of 1)
I’m in love with these cloths! I wear waterproof SPF moisturizer, foundation and mascara daily. Before discovering these cloths, removing my makeup was such a chore! Previously I had to use mineral oil to sufficiently break down the waterproof ingredients, wipe the messy oil off with a washcloth, and follow with my regular facial cleanser. Now, I only have to use 1-2 of these cloths to fully remove the products I use and follow with a cleanser! It’s so much simpler and less messy (the mineral oil would always stick around on my bathroom sink). Although these cloths cost more than the oil, they’re a time saver and I don’t put off/sleep with my makeup on anymore! They are very gentle on my skin and don’t leave any scent behind. Highly recommend these!

Excellent for sensitive skin/ allergies, best wipes I’ve ever tried!
Size: 50 Count (Pack of 1)
These are the best makeup removing wipes I’ve ever tried and that’s saying a lot.
They are incredible for removing waterproof mascara and zinc sunscreens! For so long I avoided these products, but thanks to these makeup-removing wipes, I no longer have post-sunscreen breakouts and I can easily remove my eye makeup without pulling out any eyelashes.
They’re very good for sensitive skin, too. Other makeup removing wipes (including those specifically formulated with natural ingredients for sensitive skin) caused me to have reactions. The Clinique wipes cause me no problems, stinging, or redness.
With 50 wipes in a pack, they last a really long time. Really good product, total game-changer. My skin looks wonderful after using them.
