Can nasolabial fold lines and collagen naturally reverse?

I am 28. I use moisturizer, eat right, & use SPF religiously. Overnight I looked old, my smile & mouth look different . Thought it was my lips, so i got juvederm. But then I realized something else was going on. It's so hard to see in photos, but my lower face looks like an old woman. My skin feels different, my chin skin feels bonier & nasolabial fold lines appeared. Can this naturally be reversed without filler? Filler is so expensive, should i look into fat grafting instead. I'm devastated.
