I bathe twice a day but don't linger in the bath.
Since I was a teenager after I have dried my skin and it is still is still damp, I have smothered myself in baby oil, I have never missed doing it.
Another thing I use in winter is a small Humidifier in the sitting room, it keeps the air from drying out, so no itchy skin.
Also oil the inside of your skin as well as the outer with essential fatty acids.
There is a thing called Formication that is associated with menopause, but mostly its described as a sort of crawling on the skin.
