Question

Why in winters our lips are dry and cracks very easily in comparison to summers?
How use of balms can prevent the cracking and smoothens the lips?

Answer 1

Dear student,
In winter the air is dry and cool so water present in the skin evaporates and makes our skin and lips dry. In winter we drink little amount of water which reduces the total water content of our body and evaporation makes the skin and lips dry. By using balms and petroleum jelly, forms a protective layer on our skin which prevents water in our body to come in contact with the dry air and thus prevents evaporation.
