This would depend on your age and condition of your skin. Ideally, you want to maintain proper skin health.
But we all have different skin, depending on genetics, environment, climate, etc.
One of the best things you can do for your skin is to avoid sun damage. Notice I did not say avoid the sun, which is good for you, in moderation. Sun damage is one of the main things that affects your skin. So sun blocks when you are in the sun are crucial. Wear at least a 40 SPF, and reapply at least every two hours.
If you doubt this, just look at the top of your forearm; you will note it is probably darker than the underside, which is a good way to evaluate your skin's true color. This is mostly protected from the sun.
Young people just need a good Cleanser to keep the skin clean and prevent bacterial damage and pores from being clogged. If you want a good Cleanser, try http://bareskincare.com/products/bare-skin-cleanser. This is also good for removing make-up.
If your skin is normal, I recommend a good skin care program at about age 30; that is when collagen stops being laid down, and wrinkles start. Preferably this should contain retinol, alpha and beta hydroxy acids, hydroquinone as a bleaching agent, and hydrocortisone. A good program that contains all the above is found at http://bareskincare.com/products/bare-ski-care-basic-program.
And for the best skin care line, try Bare Skin Care.
