I've seen a lot of people doing that lately.

Check out Cheongdam Q-QQ!! The Queen Bico results here are seriously good haha. I got it done too, and the before and after difference is definite; my nose looks much more pointed.

If you're in Gangnam, I recommend Ladyco. It feels like it lasts longer than fillers.

For the Gangnam or Apgujeong area, I recommend Cheongdam N or Cowon.

If you're in that area, you should also check out Blanc de Vie in Apgujeong. The director is quick-handed and has a great sense of aesthetics, so they are skilled. Since they charge per thread, they specialize in noses, throats, and more.

I go to Gangnam Bans Clinic because they do a great job with natural-looking designs and the prices are reasonable.

I'm curious too. Thanks for the information! Hahaha.
