The advantage of liquid eyeliner is that it makes the eye shape extremely clear. It won't smudge even in high temperatures or when sweating. However, its disadvantage is that it cannot be washed off with ordinary facial cleansers; it must be removed with makeup remover. Also, do not blink when the liquid eyeliner is fresh and not yet dry; if you don't press down on the upper eyelid, there will be a line!
Eye liner's strength is also to define the eye contour clearly and is easy to remove. However, its drawback is that it tends to smudge.
So if you want to save time, use an eye liner, but you'll need to touch up. If you're not afraid of the extra effort, opt for eye liner liquid.
Personally, I prefer eye liner. After all, it doesn't smudge and can last all day!
All of the above was typed by me character by character, and I only realized at the end that you don't give points!!~~T-T~~
