Ok to preface, everyone here is right, you do look perfectly fine. The lines are barely noticeable, I had to zoom in to even spot more than one. They also don't really age you, they look like normal facial expression lines.
That said, even if nobody else notices them, it's also ok to want to work on them. It's your face, not ours.
Firstly, I really do think they're mostly expression lines, i.e. not actual wrinkles. If that's actually true, you can reduce the appearance of them by drinking plenty of water and being very diligent in moisturizing. Apply a moisturizer morning and night. Don't over cleanse- for most people, it works best to use a gentle facial cleanser at night and just water in the morning. It's hard to tell from the picture, but your skin looks well hydrated in some places but not in others, so you might have combination skin. There's products specifically for that. If the small lines still bother you, you can look into a retinol serum. Those contain vitamin A and they'll make your skin renew itself faster, thus reducing the appearance of lines and slowing down the formation of new ones. Retinol makes your skin more sensitive to sun, though.
In preventing the deepening and forming of wrinkles, your best bet is to keep up what I said in the previous paragraph, as well as protect yourself from the sun. Even if your skin is of a tone that doesn't burn, the sun can cause skin cancer and also make you age faster. I myself have started using sun screen every day I go out when the sun is at least semi out, despite never having had a sun burn.
Last caveat, your skin WILL age. It's a fact of life. We can slow the aging and reduce the appearance of lines, but we have to accept that it'll happen either way. Cheers!
