Curious about nasolabial fold procedures

Wow... I was so surprised when I looked in the mirror. I didn't realize my nasolabial folds had deepened this muchㅠㅠ

I wasn't really interested when my friend said she was worried about laugh lines.

I guess I didn't realize that I'm also aging and growing old together, haha.

What treatments are available to tighten and smooth out nasolabial folds?

I'm curious whether the procedure is simple and what the effects are!!
