Hi Dear,
Welcome to HCM.
Understanding your concern.
As you asked in your query about dry lips and lip discoloration ,well this is a condition called
chapped lips .Chapped lips can occur due to many reasons like environment factors like dry weather ,excessive picking of lips ,appylying saliva with tongue frequently which takes away the natural moisture,sun burn and
nutritional deficiency. The pink color is due to inflammation of lip and dark like is due to discoloration.
I would suggest you to not to pick your lips ,do not wet it with saliva ,apply petroleum jelly for moisture ,apply sunscreen with SPF 50 and containing
zinc oxide,wash your face twice a day,drink plenty of water and take fresh fruits and vegetables in your diet.Aoe vera gel is also very effective in discoloration .
If condition persists or doesn't improve in 10 days then
consult dermatologist.
Hope your concern has been resolved.
Best Wishes,
Dr. Harry Maheshwari
