The only 3 kinds of liquid eyeliners I own are from top to bottom, Kiss Me Heroine Make, Koji Dolly Wink, and NARS stylo liner.
Kiss Me Heroine Make and Dolly Wink are pretty similar in pen size, tip, and ink quality, as I have mentioned in my previous posts. NARS stylo liner is my least favorite because of the difficulty I have with applying the ink with its dried up felt tip.
Putting the tips of the eyeliners side by side:
You can see why I love KMHM and Dolly Wink a lot. Their tips are moist with ink and so fine, 0.1mm to be exact.
A swatch of the 3 liquid eyeliners on the back of my hand:
From top to bottom, Kiss Me Heroine Make, Koji Dolly Wink, and NARS. As you can see, KMHM has a slight spreading of ink into the cracks of my skin. But I didn't notice a spread of inks when I use this eyeliner when tightlining. It also appears to me that NARS' ink is the deepest black of the three.
Putting these eyeliners to the test of its waterproof qualities:
All of the liquid eyeliners did not smudge under water. That's a good sign!
Moving on with the ease of cleansing with makeup remover. Here I use my Shu Uemura make up cleansing oil and gently spread across the three swatches.
NARS is the first one to go. Both KMHM and Dolly Wink stay here. After a few more rubs and emulsifying with water, they are going away too.
I feel like these eyeliners are easier to clean than Majolica Majorca's mascaras. So my verdict? I will go for Kiss Me Heroine Make or Dolly Wink. Definitely will not be repurchasing the NARS stylo liquid eyeliner.
