Hi..
Welcome to HEALTHCARE MAGIC.
I have gone through your query and can understand your concerns..
As per your complain
smoking bong has led to continuous irritation of the lips with head as well as friction leading to
Hyperpigmentation..
Although suck kind of hyperpigmentation is tough to remove and can take a long time to start fading..
You need to first of all stop smoking all kinds of recreational drugs
You can start applying creams containing
Kojic acid and
glycolic acid over the lips..
You should exfoliate your lips with a mild scrub..
You can also apply Honey over lips as it will help in
depigmentation..
Scrubbing your lips with a piece of lemon and sprinkle common salt over it as it will act as a natural scrub..
Do cool compresses over lips..
You should apply SPF 15 containing lip balm over lips when going into sun..
Hope this information helps..
Thanks and regards.
