I'm stressed because my forehead looks so flat from the side, haha. I want to fill it in, but I'm worried it might end up looking bumpy.

It seems really hard to find information on places that do forehead fillers well.

Are there any good places that add volume naturally?

I'm planning to go around Gangnam or Sinsa to look for places, but I'm so nervous, haha. I want to go to a place that does it just right—not too much, but pretty and perfect.
