I think it's perfect for those who want a lush, eye-catching look!
It gives you perfectly voluminous, doll-like lashes. It doesn't turn them like seaweed, and it separates them nicely. Applying multiple layers achieves the desired volume, but at first, the liquid didn't adhere to your lashes at all, which was a bit surprising, so be careful. The brush is quite large, and the liquid has a crisp, low viscosity, typical of waterproof products, so it's difficult to apply to your soft, natural lashes. Applying multiple layers firms your lashes, making them more voluminous. It doesn't smudge at all, even during the day. It's also resistant to eye drops and pollen-related watery eyes. In terms of effectiveness, I'd say the order is volume > separation > curl > length. The lengthening effect isn't weak, but if I had to choose between the two, I'd go for the volume type. It doesn't have any shine. It gives you crisp, stage-worthy lashes. It's only available in a simple black. Apparently, there's also a brown version that washes off with hot water, so it would be nice if more of that was available. Fancl's cleansing oil didn't remove it completely. I want it to come off in one go, but it's a pain. I need an eye makeup remover. MAC sometimes has promotions on their official online store, like 20% off, so I buy in bulk when that happens. It's a pretty good value for money because it's a fairly large 12ml bottle.
I'm on my second purchase. This mascara is designed to make your eyelashes thicker rather than longer. I like to use it on my upper lashes. I'm part of a generation where applying it to my lower lashes makes me look like a Heisei-era gal. I know I should be more careful about how I apply it, but I can't. I'm part of a generation full of energetic high school girls. It won't come off even if I cry or swim. But it comes off easily with a point remover.
Someone I follow on X was using it, so I immediately bought it. The packaging design is really cute, and the waterproof effect is a big help. It doesn't give you panda eyes.
