Best way to prevent wrinkles from forming in the future?

I don't smoke, I don't tan, and I try to use moisturizer a couple times a week. But I make a lot of facial expressions and can already see a visible line smack-dab in the middle of my forehead, a similar line as my mom's that's now really prominent in her forehead (she's in her mid-40s). I love smile wrinkles but is there any way to prevent this awfully deep line and others from becoming bad in my 30s, 40s, and beyond? I'm only 16 right now, and I can already see it starting to form—is there actually any specifically designed formula for preventing aging instead of reversing its effects?

Kind of a weird question, but thanks for your help!
