First...you didn't get your wrinkles overnight and you aren't going to get rid of them overnight with magic cream!
Start drinking more water....stop drinking diet soda, stop smoking (if you smoke) and stop exposing your face in the sun...you'll be surprised how much this will help.
Next, depending on what kind of skin you have will determine what kind of skincare you should use. Don't go out and get bamboozled into buying an entire line of expensive skincare. Any really great skin care will give you samples and will let you try it first. Go to Neimans/Nordstroms and get a free facial ...they will gladly give you a facial because they want to sell you their line. Ask for a bunch of samples and buy maybe one item first. Try it and if you like the results, buy something else in that line. If you don't like the results, return it and get something from another line (that's the nice thing about Nordstrom/Neimans because they will allow you return anything for any reason even if you've used some of it). Also, remember, any skincare will take at least 2 weeks before you start really seeing results. personally, my favorite lines are sisley, darphin and natura bisse (sisley my absolute favorite). But you need to find what's right for you. it's pretty expensive, but you really can't replace your face. it's an investment in you......also, I'd recommend holding off on the botox for awhile....it's very expensive and these other things might do the trick. good luck with your new life and new you!
