20, large pores, combination skin? (Photo)

Hi, im 20 and have combination skin with visible pores. I do not know what type of serum i should be using, those with retin A ? Is it okay to use a foam cleanser as i feel after washing with it my face feels dry. Is that a good thing or should i stick to a gel cleanser ? Also, because i am only 20 would that be alright to start using anti aging products ? Is it true that by starting early you can prevent early aging ?
