JayMan, you need the "trinity" of a good, photostable and UVA protective sunscreen, a retinoid product for night-time use (order a Retin-A cream from an online pharmacy) and maybe an antioxidant serum like SkinCeuticals vit C.
Here's tetrakis' (from makeupalley.com) advice:

Question: What is is the minimum routine necessary to prevent aging of the skin?
Answers: My advice is that you don't need to use a 'specific line' to combat and prevent aging . You only need to know what ingredients really *work* and what's hype =)
The general consensus on the boards is that there are at least 3 things that you need to prevent aging. All of these 3 things are clinically (medically and scientifically) proven to keep your skin young.
1) SUNSCREEN. This is probably the most important. Some experts estimate that daily sunscreen use can cut down on as much as 80-90% of aging. Please see the ''sunscreens" notepad and 'sunscreenfaq' notepad on makeupalley.com for more information.
2) antioxidants. Oxidation is another key factor that causes damage to our DNA and tissue which = aging. The most clinically relevant antioxidant is vitamin C . It has been shown to further protect the skin, above and beyond what s/s can do, from UV damage when used in the morning. It also promotes collagen production and evening of the skin tone .

Also, see what C can do for the skin here:

This woman had extensive sun damage and erythmea before treatment. Notice the decrease in inflammation and deep lines. I believe the formula used in this study is similar to the skinmedica anhydrous C formula.
It is best to ask the ladies on the skincare board for vitamin C serum recommendations if you wish to buy a commerical one. My favorites are: Skinceuticals C and E Ferulic. I cannot recommend it personally (allergy to one of the ingredients), but I will say that it has good research showing it is an extremely powerful antioxidant potion. Link here:

And Skinmedica vitamin C complex. I would recommend the skinceuticals for oily skin, skinmedica for dry. See a picture of what skinmedica can do in my profile or in the link above (that's not me, by the way, it's a photo from a published paper =).

3) retinoids. You can see the Q & A section below for more information about all the functions of retinoids in the skin. 20s is a good time to start using an OTC retinoid to prevent aging and treat any photoaging you may have accumulated already (and most of us accumulate most of our UV-related damage before we hit our 20s...all those years of runninng around with no s/s on as a kid =(. Some people will tell you that 20s is too young to start with retinoids, but these people are telling you this as a matter of opinion, not fact. The medical community advises that teens and 20s is a great time to begin this form of prevention and treatment.
My favorite OTC retinoids are avene's retinaldehyde products. Read more about ingredients and where to get them here:

and how they work below in the Q and A section.
You could try other OTC retinoids like *retinol* (neutrogena and RoC both make good formulas) if you don't want to order retinaldehyde products, but elsewhere in my notepad I specifically address why retinaldehyde is better than retinol (at least, when they are at matched concentrations) in the Q & A section. Not to say that retinol doesn't have some benefit for the skin, but I believe retinaldehyde is better (unless you can get your hands on an outrageous concentration of retinol...highest I have seen is from skinceuticals).
