My Skin on the elbows(hands) become icchi, rough and loosen. I applied cocnut oil but still no use. I stopped smoking from last 20 days is at a syptom of quitting somke. I am really worried. Also my skin near my lap always gets icchi. I have this icchi skin near lap from long time. I noticed the skin changing different from the rest of my body near my elbows. Is there any one who can suggest some remidy or soulution for this and the exact reason for this icchi skin at the elbows. Is it defficiency

Thanks in advance
