i went through the same thing, i have extremely dry skin and when i don't treat it the skin start to have white flakes forming and start to crack and bleed. Although when i start to treat it with moisturizers i get itchy and red and they don't work. I realize later that non of them helps or helps only temporarily. I found out that the commercial moisturizer creams contain alot of chemicals which cause me to have redness/swelling reaction and they don't work.
Now I've tried the DERMA ointment from DERMACOP, it works fantastic and it's natural. I Have no allergic reactions to it whatsoever, i notice results in just one day. It not only moisturizing my skin, but keeps my hands look clean and younger, it's amazing. Now my hands are not easily dry or crack like before, even in extreme cold weather. I'd recommend anyone with constant dry skin on hands, feet or body to try it.
