Can a laser help this extra skin when I smile, or would I need a lower eyelid surgery? (Photos)

I have a healthy lifestyle and I’m constantly being told that I look like I’m young and in my 30s. The only thing that is giving my age away is when I smile. I have this extra skin under my eyes. It just started six months ago out of nowhere. I get eight or nine hours of sleep at night, I live very stress-free, I only drink water and exercise and everything. How on earth did this happen And would getting laser or even threads help?
