Tricked you? No, TikTok’s latest, super-sultry lipstick trend will save you. You’ve probably come across plenty of hacks to over-line lips through TikTok, whether it’s Mario Dedanovick’s lip lift technique, pursing your lips together to line the edges, or oval-lining. The newest lip liner hack, “siren lips,” is completely different—and the result is incredibly alluring. 

“Siren lips” are similar to “siren eyes,” another TikTok makeup trend that’s going viral right now. “Siren eyes” are essentially a smoked-out cat eye that give eyes an elongated effect. “Siren lips” also play off of this concept. The basic idea is simple: overline your lips as usual, using a slightly darker lip liner than your lipstick color, and extend the edge line a bit past where your natural lips end. Think “the Joker” but make it sexy. 

Since this lip trend is going to be everywhere, I had to try it for myself. I was worried I might look cartoonish, or like I was literally trying to look like “the Joker.” In reality, this slight extension on my lips made me look like I was slightly smiling without really trying to—and I’ll definitely be trying the hack again.
