What age do you start getting wrinkles?

I ask, because I am in my late 40s and I don't have any. Not to brag but to ask if they start showing up later in life or do we all just look a lot younger now a days to genetics and taking better care of ourselves? I don't do anything super special just use all water based moisturizers and cleansers. I use Neutrogena Hydro Boost line FYI.

In case anyone asks, I look way younger than I am. I am the Winona Ryder of my world. I'll look young forever probably LOL.
