Loose Skin with Ab Vacuums

[jxn]

When I am standing up straight, my stomach is flat and shows no signs of loose skin. When I do an ab vacuum or lean over, though, it looks like I have a ton of loose skin waiting to come out once I lose more weight. The first picture is what my stomach looks like standing straight, and the second is what it looks like leaning over.

Is this likely loose skin or just stubborn body fat? Thanks for any feedback.

I think a bit of both. It probably won't all go away but if you stay strict with your diet/workout regimen it should improve. But don't expect for it to all go away. And even then, it's somewhat normal for it to be like that when you bend over.
