South korea is the world's capital of cosmetic surgery. Most korean women there get it done....I'm sure you are aware of that. There's a brand that specializes in tourists going to SK to get it done, I forgot what its called now.... you might want to do further research on this.
Great prices too.....
I use some Korean and Japanese skin care products, actually.
Btw..... I would recommend you getting a Photoshopped picture of you with a v line to see if you like it before actually going along with it.
