Andrea - Thank you for the compliment!  Growing up in Florida IS high risk for skin cancer and wrinkles.   Since you already know that you have more sun damage than average for your age, I'd recommend going to the prescription strength tretinoin 0.025% (Retin A) or you might like Renova (tretinoin 0.02%) better because it's in a more moisturizing base.

  I'd recommend for morning a gentle cleanser, a good antioxidant like SkinCeuticals C & E Ferrulic (as long as not irritating) with sunscreen (5-10 zinc at least) over that.  The antioxidant will potentiate the sunscreen.  At night, wash, moisturize, wait 10 minutes and then your Renova.  Lots of hats with wide brims if you can! Exfoliate GENTLY once a week.  The tretinoin helps to exfoliate already.
