For defined eyes, use Merzy The First Pen Eyeliner

I have oily skin and watery eyes due to rhinitis, so my eye makeup tends to smudge easily.

I used to use pencil eyeliner, but no matter how soft the formula was, it irritated the area around my eyes.

Brush pens smudge easily with tears, so I use a pen eyeliner, and the staying power is really good even with oil and tears.

I like it because it is thin, neat, and, above all, applies smoothly without irritation.
