Review: Goes on thin. No clumping! - If you don't like clumpy eyeliner and are sick and tired of trying all the other kinds. This is the best mascara ever! It goes on thin, spreading your lashes.
Review: A must read! - I am 52 years old and I had been searching for a good mascara since forever. Yes this one is a bit pricy but it is so worth the money. You will not be disappointed! The wand gets every individual eyelash and does not clump or flake. I was playing around with it and put 3 coats on just to see if it would clump or flake and it did not. I can actually get my bottom lashes easily without getting it all over my skin. I can go on and on about this mascara but you get the point. I will forever and always buy this kind as long as it’s available. 💯❤️

## Features

- Tightline Lash Thickening Black Mascara Primer is a bestselling, award-winning black lash primer, eyeliner, and mascara - all in one.
- This black, lash defining and lengthening mascara primer lays down black pigment between each and every lash for instant tightline eyeliner definition and the look of a fuller lash line.
- Unlike most mascara brushes that leave the first third of your lash roots bare, this groundbreaking skinny wand separates individual lashes and coats your lashes at the roots for a beautiful lengthening and defining effect.

### ⭐⭐⭐⭐⭐ An essential!
*by S***R on January 3, 2026*

Listed as a primer but it's really a mascara. Excellent on bottom lashes. Used for yrs but I wouldn't consider it an eyeliner. You really can get close to the under rim easily. In my 70's now and hope it's never discontinued. Also wears all day without smudging.
