Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain dryness and black crust on lips is due to a condition known as
CHAPPED LIPS.
It can be due to long standing
dehydration, excessive exposure to sun, habit of licking lips,
Vitamin deficiency etc..
Nothing to worry, Apply petroleum jelly or bees wax containing lip balm over the lips as it locks moisture and lubricate the lips and prevent dryness..
When you are exposed to sun always apply a broad spectrum SPF 15 containing lip balm..
Cover your lips with a scarf when exposed to
cold air and even sun.
Drink plenty of water..
Avoid biting or licking the lips..
Avoid application of any harsh chemicals containing lip product..
Do cold compresses over lips..
Once they become soft start exfoliating the lips with a mixture of homemade scrub like honey and oats..
Take a
multivitamin tablet daily for 1 month..
Hope this information helps..
