Nasolabial folds in teenager who lost weight. Would getting fat again help? Or could the real culprit be stress?

I am 18 years old and getting deep laugh lines that make me look 30. I had and still have a large accumulation of abdominal fat. Over the past year I lost 15 lbs, but as a result I now have these hideous lines. I would rather be fat than have them, but is it too late? Everyone in my family lives to 80 anyways, and no one looks like this. I'd gladly trade 10 years to be able to enjoy my youth. And do not suggest plastic surgery. You will look like a tool if you suggest surgery to an 18 year old.
