Frequently Asked Questions
You've got questions, we've got answers
What is the finish?
Hotliner has a satin finish—not flat matte or glossy—so it looks soft and natural while still giving definition and polish.
Is Hotliner fully pigmented or more buildable?
Hotliner has rich pigment payoff in one swipe, but it’s also buildable so you can customize your look—from subtle definition to bold, statement lips.
Is Hotliner long-wear?
Yes! It’s clinically tested to be longwearing for 8 hours while remaining comfortable, creamy, and non-drying.
Is Hotliner waterproof?
Hotliner is not waterproof, but it’s formulated to resist feathering and fading for up to 8 hours. It stands up beautifully to daily wear, eating, and light drinking.
How do I best apply Hotliner?
There are endless ways to use Hotliner—there’s no wrong way to wear it! Outline lips: Define or slightly overline at the cupid’s bow and bottom center for a fuller shape. Diffuse: Smudge with your fingertip or use the built-in brush for a soft, lived-in look. Layer: Pair with Wet Stick for soft shine or top with Wet Lip Oil Gloss for a juicy, glossy finish.
Do I need to sharpen my Hotliner?
Not every time! The tip stays precise for multiple uses, but there’s a built-in sharpener to create a thinner, defined line when you want extra precision.
How do I use the brush?
After lining, use the brush to blend edges for a more natural look or to soften the color for an effortless blurred-lip effect.

It’s good.
I use it with the bold lip oil, plain gloss or even a pinkish base. Works well with a lot- which I was nervous about. Perfect pop if you are leaning into reds/pinks with a little more warm tone than the cooler pinks that a lot of the shades trend into.
Long story short. Get it. It’s good.

This is my 2nd lip liner. I love both colors I’ve bought. Apply smoothly and easily and stay on a long time. I like over-lining and filling in the entire lip with the liner.

I love the vibrant color and how easily it glides on. I was surprised at how long it lasted. Definitely cant wait to try some other colors.

Absolutely love this lip liner. It pairs great with the lip oil gloss. I purchased one and received this one as a gift. Great color and glides on smoothly. The color is neutral and beautiful. Will repurchase. I am new to Kosas but love the many products I’ve tried and now continue to use. Highly recommend
