I am going college and the air-conditioning in there is extremely cold. Even when wearing a sweater you feel like your freezing.When my classes finish most of the times I have to go out into the extremely hot sun. As a result of these conditions, my lips have gotten black burnt marks on them but they are not hurting nor are they red or swollen of any kind. There are just black marks on them. Tomorrow is my birthday and I am not a bit excited because my lips look black and burnt. Can anyone share a remedy to help get rid of these marks pllzzzz?? Thankz much.

I don't see a connection between ac and the problem with your lips. Are you possibly anemic? Have you seen a doctor about any of this?

I think you should not drink cold water but just warm water. Try to keep warm. Maybe wear a sweater and a jacket ontop. Wear jeans and boots. LOL I don't know...

Its not just the ac. I live in Trinidad and when I come out of that extremely cold place I have to go directly into the hot sun and as a result of the sudden change in temp my lips became like that. No I am not anemic. They usually get blistered but my lip balm heals it quickly but this time they are not blistered at all. They just have darks marks on them as if they have been burnt.
