With the exception of your forehead, the rest of it looks like normal things that happen when you smile. I don't see wrinkles there. You don't want to get rid of that - you have a nice face, and what looks like a nice smile.
You do have some lines on your forehead when you make them appear that way, but before doing anything, how do they look when your face is at rest?
How's your lifestyle overall? Are you getting enough sleep? Are you staying hydrated? Eating well? Exercising? Moisturizing?
I have the whitest of white skin, too, and it does show every little thing. I look at the sun from inside and get freckles. If you decide to do anything, ONLY do it under the care of a certified/licensed dermatologist. Don't do it yourself, and don't buy some kit at the store.
But really, you have a nice face. Teen years are full of hormone changes that do awful things to our skin. See a dermatologist if you must, but I suspect you think it's really bad when it really isn't. :)
