Last long
Color: BLACKEST BLACK, Size: 0.24 Fl Oz (Pack of 1)
Absolutely love this Maybelline mascara! It makes my lashes look longer, fuller, and more defined without clumping. The formula lasts all day and doesn’t smudge easily. It’s affordable, easy to apply, and gives such a beautiful lash look.”

A perfect natural glam mascara
Color: PLUM TWILIGHT, Size: 0.24 Fl Oz (Pack of 1)
I have been searching for my ultimate, every day mascara for at least 10 years & I actually tried this one about 4 or 5 years ago (not in this shade though) and I remember it being a strong like at the time but not “the one”. Buuut this might be the one. Went on smoothly with minimal clumping. Elongated and curved my lashes upwards without using an eyelash curler. Held up for 9 hours in humid, sticky conditions and is still going strong. No flaking, smudging or transfer. I do wish the brush was different, or had longer bristles at least, but not enough to dock a star over. The plum shade is gorgeous and veers toward black in some lighting but has just enough color to enhance the eyes. It didn’t add a ton of volume, but enough to be noticeable and I actually prefer that because I have sensory issues with my eyes and that is why I sadly can’t do falsies. All in all, this is a 5 star, every day, natural glam mascara and now I want to try the green.

I use these cotton rounds every single day, and they’ve become a staple in my skincare routine. They’re soft, gentle on the skin, and work perfectly for removing makeup or applying toner. The quality is excellent—they hold together well and don’t fall apart during use. For the amount you get, the price is really hard to beat, making them a great value for everyday use.
