The YSL Couture Eye Liner's tip is extremely precise, allowing me to draw ultra-fine lines effortlessly. It's like an artist's brush for the eyes.

The thin tip of this eyeliner is great for filling in the gaps between my lashes. It gives a natural look while still defining my eyes. It's very versatile in terms of the looks it can create.

The long-wearing formula of this eyeliner is truly remarkable. I've worn it through sweaty workouts and it still looks flawless. It's waterproof and smudge-proof, just as advertised.

I like that this eyeliner doesn't flake off. Some eyeliners can leave little bits of product on my cheeks, but this one stays intact and looks clean all day.

YSL's COUTURE EYE LINER is a treasure among eyeliners! The tip of the pen is so fine that even a clumsy person like me can easily control it and draw smooth eyeliner. The color is even and rich, and the matte, satin and pearlescent textures are all different. It is waterproof and smudge-proof, so you can wear it all day without any pressure, and your eye makeup is always clean and neat. The packaging is exquisite and feels very textured in your hand. Beauty lovers must try it!
