This is Black Pink's Jennie pre-debut. As you can see, she looks kinda different but still very cute. The first thing I noticed is her darker skin tone (not saying that there is anything wrong with her skin tone at the picture). It could be the lightning, but there is a big possibility that she lightened her skin. It is very common thing to do in South Korea so that is nothing surprising. Besides that, i cannot notice anything too different from now.

But, if you take a look at her eyes, it seems like she had double eyelid surgery. I don't think she is wearing double eyelid tape or glue. 

And for her nose, I think it is natural. If you look at some old videos (for example G-dragon's Black and that xx) her nose looks the same to me. 

Maybe she has some fillers or something like that, but to me it seems like she is quite natural.
