You are never too young to benefit from a good skin care routine. With wrinkles, prevention is the best way! I started using anti aging, eye creams, etc when I was 17. Im now 19 and I still keep up with a really good routine. I dont see a difference now but I will in 10 or 20 years time! Also, SPF! UV rays are one of the biggest causes of premature aging.
Of course you will get some creases from facial movements. I have a few under my eyes from smiling and you can use a filler primer that smoothes out any little lines to stop your makeup creasing. Also alot of foundations have this built in.
I hope this helps! 🙂
