My family recently moved from sunny Costa Rica to Texas and we happen to make it for a 12 inch snow fall. My 9 year old daughter played outside in the snow and her lips became chapped and dry around her lips. The area around her lips has turnedd dark brown, I applied neosporin and later cold sore treatment thinking that is what is was. A week has passed and the white dryness has disappeared but the dark discoloration has not. My daughter is hispanic and already has a light tan color but I am concerned the dark patch around her mouth will not go away.
Any other medications I should be using? Do you think the discoloration is permanent?
