Line in between upper belly? Will liposuction help? (Photo)

Hi, I am 5'3 and 136 pounds and am 19 YO. I was wondering if it was normal to have this line in between my belly? If I lose weight maybe 20 pounds or so, would it go away? Or is it a matter of toning up? I am thinking about getting a BBL in a couple years so will liposuction of the area help? Thank you
