If they're the result of habitual facial movements, like constant raising of the eyebrows, then I recommend Botox to paralyze that muscle. The more you keep making certain expressions, the stronger those facial muscles get and the deeper those wrinkles become. All the peels and creams in the world won't do much if you're continually "training" the very facial muscles that create those wrinkles.
If you still have lines when you're face is relaxed, then there several options. Retin A type creams (I use Evita which is a mild form) are good because they help speed up cell turnover and collegen production. I also have microdermabrasion every 2 months or so, alternating with a mild chemical peel. Not only do these help with exfoliation and smoothing lines, they also keep pores clean. One thing you need to watch out for is not overtreating your skin and getting it irritated, which can cause breakouts, over-dryness and even more lines. How much and what type of treatments depend on your skin type.
A good book is The Wrinkle Cure by NV Perricone. Nothing will "cure" wrinkles, but the book has a lot of good information about skin care and options.
