Dry scales of skin? - I have freckles ...

Hi,

I'm northern Irish and have fair freckled skin. I'm 53 years old. I saw a dermatologist in my 40s and had some large freckles and visible veins removed from my face. (roseacea).

But now I have a few areas on my arms and legs of dry scales, like a dried up freckle that peels off regularly. I pick at them on my arm and legs and I probably shouldn't. does anybody have an idea of what it is? The dry scale patches aren't dark like a mole, I probably should consult a dermatologist as I've had many sunburns and I worry about my freckles not being freckles.
