Does anyone know great skin care information?

Im 18 years old, and I think its important to start taking good care of skin at an early age. Im trying to figure out what i should do now so that when i get older my skin will be in prime condition. I dont have acne problems or dryness problems but my skin doesnt look as healthy as can be or flawless. I also dont want to use chemical skin care because in the long run it only harms the skin. Natural, safe, and affordable products is what im looking for. Does anyone know a secret i can use?
