Physicians FormulaEye Booster 2-in-1 Lash Boosting Ergonomic Felt-Tip Eyeliner Plus Serum, Ultra Black, 0.016 Fluid Ounce

Love this. Waterproof and stays on all day long without smudging. Came off a little with heavy duty sweating but other then that perfect. Smooth lines that are easy to control.

I loved the older version of this eyeliner, which was the traditional pencil-shaped. This version’s tip is stiffer and less flexible, which I don’t like as much, but I still love the formula. Very black and stays all day.

I bought this for my GF and this is her review:Was very excited about trying this eyeliner but...It kind of last but at the same time it doesn't? Because it moves, it doesn't stay put. It does smudges and fades. Not as black, has to go over it a few times. Feels like it doesn't dry all the way. Can't get it off with just water or else it gets messy. Would not recommend, unless u have a way of keeping it put.Eyelashes improvement? Couldn't use it for long, so not able to say.

Absolutely love this product! Very easy to apply. It even stays on during a hard workout at the gym and washes off easily. Store in downright position for best used

Looks good, works great- unfortunately it irritates my eyes.

I love this product. I have tried various eyeliners (pencils and brushes, liquid and dry) and this by far is the easiest method. The felt tip marker does not bend or bleed. It is easy to contour along the eyelash line without making mistakes. It is not as dark as other eyeliners and needs more than one layer unless it’s within the first few times of using it. My only complaint is that it doesn’t seem to last very long. I use it almost daily and I need a new one every two to three months. I always have a spare handy. Being how foolproof it is to apply, I think it’s worth it. It’s easy to make wingtips or go light for a more natural look.

im on my computer so i cant post a picture. ive never tried this before but it arrived and it was hard to apply seemed dried out. then the next day same after a few days it was dried out it didnt want to apply. im thinking it was empty. it was cheap so no biggy but i really need something to last at least a few months.

Compared to the old design this one is easier to get the cap off and hold. The tip is a bit easier than the old design also cuz it’s more rigid. I like that I don’t have to keep using the cap to pump more product into the tip. It just comes out like a marker would.

I’m on my second one now. Best eyeliner I’ve ever had!

Love this product...my second one.

Came with day earlier than expected. Smooth and dark love it
