Small wrinkles at 21?

Just a few days ago I noticed I have a few wrinkles. Under my eyes and on my forehead.

You have to go really close to the mirror to see them and they're only visible under a certain light, but they are there.
And I don't want them there. I haven't dated a lot, never really had a boyfriend, never had sex and I don't want to start looking old yet
I don't get why I have them in the first place? I have good skinny usually. Very pale for sure but I use sunscreen, I drink a lot, I use moisturizer, don't drink or smoke. I avoid the sun like a vampire, I eat healthy. Why do I have wrinkles?

I think they're too small to really see them on a picture. All the ones I took failed and it was hard to find something comparable online too. This is the best I got
