Hello and thanks for posting your query to HCM.
We can understand your concern regarding pigmentation problem of your kid. Lichen Planus Pigmentosus
is a pigmentary disorder seen in Indians with macular hyperpigmentation
involving chiefly the face, neck and upper limbs
and can be even more widespread. The main problem with this condition is the visible appearance of the color which makes us more concerned about the problem. Now for the treatment part, there is no established therapy for this condition which can either reduce of the hyper-pigmentation or stop the progression. As the problem is persistent in nature and slowly extends so at a point of time all types of treatment proves to be of little help.
The treatment given to your child is fine but again you have to understand that can not be given for very long period of time. There are certain measures, though not established methods, but can be helpful :
1. Strict sun avoidance
2. Any oral medications if you take then make it sure that it should not cause progression or even photo aggravation by sun light.
3. Increase the amount of vitamin A
and carotenoids and other related antioxidants
in the diet
4. Increase the intake of fruits and green vegetables
At last you should understand the problem your child is facing is a simple pigmentary condition and not at all a dangerous condition which can never cause any problem in his/her future life in any physical mode. So be relaxed, some times we have seen gradual improvement without any therapies also.
With best wishes for your child's health,
