It sounds as if you’re already doing the right things to take good care of your skin, but I think you would benefit greatly from the use of a gentle Alpha/Beta Hydroxy treatment.
AHA’s and BHA’s do a wonderful job of removing the top layers of
the epidermis to reveal fresher, moister skin. Fine lines become
less noticeable, and you’ll probably notice a rosy glow. You
don’t need to spend lots of money either; I love Neutrogena Healthy Skin Anti-Wrinkle Cream! You can’t beat it for the price, and it is very effective! You might also want to consider Prescriptives All You Need cream, which has everything you need for wonderful looking skin, all in one formula.
Something to remember: always use a sunscreen, especially when
using AHA’s or BHA’s. Because the skin being exposed is more
delicate, you’ll need to make sure it is well protected by using
a broad spectrum (UVA/UVB) sunscreen. But you should be doing
that already, and I’m sure you know that 
Sun exposure without
proper protection does great damage to skin, and causes all
sorts of problems like premature aging, wrinkling,
discoloration, or worst case scenario, skin cancer. I like
sunscreens by Peter Thomas Roth and Blisslabs, but Oil of Olay
makes a fabulous Olay Complete UV Protective Moisture Lotion SPF 15 full spectrum sunscreen, if you prefer to spend less (and who doesn’t?).
As far as drinking water goes, you should definitely be drinking
at least 8 full 8oz. glasses of water per day, and even more if
you are active or exercise regularly. I personally drink about 12
glasses a day, and cannot overstate its importance in
maintaining moist skin. Water hydrates your body, flushes out
toxins, and is essential to cell activity. Water consumption is
the cornerstone of a healthy body!
Hope this helps, and thanks so much for writing!
