I love this product, but it went from ok to bad. I liked the eyeliner that you just rolled up to use, except it was so soft I lost half of it through breakage. The company kindly sent me the improved version for shipping costs and I like it less. The formula is great and goes on so smoothly and stays on, but this one you have to use a sharpener. I will not reorder.

I received this product in exchange for an honest review from PinchMe. I usually stick to my usual eyeliner and I'm scared to try new ones so this sample was perfect. I was skeptical but this glides on so smooth. It's been really hot so it's hard to determine how long it lasts because my skin gets really oily in the heat, but when I'm in the office, it's perfect.

I’ve been using the ILIA Thru Line Waterproof Eyeliner for a couple of weeks now, and it’s honestly amazing. The precision tip glides on so smoothly without tugging on the eyelid, making it super easy to get a sharp wing or a soft smudge. What really impressed me is the wear time—it genuinely stays put all day without smudging or fading, even through a long workday and a sweaty gym session, yet it doesn’t feel heavy or dry. If you want a clean, long-lasting liner that actually lives up to the waterproof claim, this one is definitely worth grabbing. It’s a great product overall !
