Dear sir/mam, My skin is very dry and my lips are always cracked. I tried vaseline, boro plus and other petroleum jelly products but when I left them for 3-4 days then my lips cracks again and sometimes it pains. I never smoke or use any kind of alcoholic product. And I am very health conscious, I eat simple food. (even I don't take fast food). Please tell me solution. My age is 25, single.
