While I cannot comment on this product because I have never used it, I will say the skin on my arms and legs gets so dry in winter as well. I can't remember what I was watching one evening, but a dermatologist was on the panel. They were talking about dry winter skin. Her recommendation...do not buy all those lotions, potions and "super" hydrating creams/lotions. They all contain alcohol, further drying your skin. The best thing for dry skin is go to your grocery store, buy a bottle of coconut oil or olive oil and lightly use that as your daily moisturizer. It's pure and extremely hydrating and healing.
I used to use olive oil on my hair a long time ago when I used brush rollers in my hair 😵💫and my hair was always beautiful and shiny and soft. I have several OO in my cabinet and I am going to start using the light version on my skin.
