dark circle around lips

[maya10]

My daughter who is 10 year old and has history of mild eczema maily on the hands developed very dry lips two weeks ago.First week we applyed E45 cream and it got better.
Next week while eating something spicy her lips flared up and again she suffred from dry chapped lips.she started licking her lips but may be 10 times a day..so we applied butter on her lips ..which was salted.
now her dry lips have been cured with no dryness or discomfort but she has devleoped perioral pigmentation ..which is dark circle around her lips..look like moustache
Gp has prescribed 1% hydrocortisone..but pigmentation is still very apparent and very dark.
what could be the cause of this.does this goes away?
We are from india.
My daughter is eating mangoes from last month but not allerigic  to them as she always have them in season.
Please respond

Thanks a lot for your input...i wont for sure have any fading cream on my daughter...laser treatment is also not an option i mean she is just 10...if this does not go say in 2 years time than may be i will have to consider it.Have you come across presistant childhod pigmentation ...how would you treat it. Our families are in Mumbai/pune...so choosing dermatologist is going to be a challenge.
