I'm been using this make up remover for years!
Style: Original, Size: 25 Count (Pack of 2)
I’ve been using Neutrogena Makeup Remover for a while now, and it does an amazing job at removing makeup quickly and easily. It takes off everything—even waterproof mascara—without needing to rub too hard. What I really like is how gentle it feels on my skin. It doesn’t leave any irritation or greasy residue, and my face feels clean and refreshed after using it. It’s also super convenient, especially the wipes they’re perfect for travel or those nights when you’re too tired for a full routine. The only downside is that the wipes can dry out if the package isn’t sealed properly, so make sure to close it tightly. Overall, a reliable and effective makeup remover that I always keep on hand!

Not good for sensitive skin
Style: Original, Size: 25 Count (Pack of 2)
Not great for sensitive skin. But great for cleaning brushes or removing makeup if you have nothing else. Left my sensitive skin burning.
