I get them too...
the only tried and true method of not getting them is to not laugh, eat or make any facial expressions whatsoever. which if your me it doesn't work out. what I've found to be the best method is to use moisturizer twice a day(am & pm)(keeps skins elasticity) and to make sure that I never put too much face powder/concealor etc near there. other than that there's really not too much you can do, anti-wrinkle products aren't meant for that area of your face and you don't want to start using them in your teens. in the scheme of things-at least that means your smiling and laughing, which is always great.
