What is an effective skin care system?

My skin has age spots/sun spots, is uneven in color, dull, and has large pores on my nose. I want an effective skin care system that will brighten my skin, lighten my spots, and over all give me younger looking skin (I am 36). I am confused on which system to purchase. I don’t want to keep wasting money on products that don’t work. Dior, good skin, Patricia Wexler, Boots, etc, etc, etc! What works???

Is there a good skin care product that will clear skin while improving the health of your skin?

I've noticed that most skin care products are used to treat only acne, or only aging/wrinkles. Are there any products that combine both? I tend to have greasy skin, but it dries out VERY easily with certain products. It's very dry during winter months, but greasier during summer. I also have VERY large pores.
I was looking at "Natural Advantage" skin care line, but don't know if it'll be an effective acne treatment? I want HEALTHY, YOUNG looking skin as well as CLEAR skin. Any suggestions?

Do any of you have recommendations on skin care products for oily skin?

Hi! I have oily skin, large pores, and lots of black heads on my nose and cheek area. I wanted to know about any skin care products that would help my skin to become less oily and that would help my pores to be unclogged so the appearance of the blackheads would be less, and maybe even shrink the pores too.
But I would like the recommended products to be reasonably priced, nothing pricey because I don’t have that kind of money to be buying expensive products.
thanks in advanced!

Is it bad to use anti-aging products on young skin?

Im only 20 but i have started to notice little wrinkles and large pores and my skin isn't as elastic as all my friends. It's not really all that noticeable but whenever i see myself and then a friend, i can notice that i don't have the same glow and the same smoothness. I guess it's because I was never serious about sunscreen and my acne leaves serious marks
So i was wondering if any one knows that if I started using anti-aging products, would that backfire later on when i really need it in my 30's and beyond, by not working as well anymore? and what exactly can i do to get that same kind of skin that all other 20 year olds have?
I'm really sick of this and its really lowering my self esteem. please help
I didnt mean to offend anyone in their 30's and beyond.
Let me make what I meant a little more clear.
I read the back of an anti-aging product and it said something like: around age 30 your skin starts to show visible signs of aging.
So i didn't mean that as soon as one hits 30, they're gonna start having wrinkly skin or anything like that, I just used that number since that is the age range where most people start to see the need for using anti-aging product, according to the anti-aging product I read the claim on.
