Hi, thanks for posting your query
I can understand your concern
is given which might have lead to aquired ochronosis in your case, so you can use,banatan cream in the morning and kojic cream at night.you can use these for two months and review with your doctor
. you may take some sessions of glycolic peels .
hhsone has momatosone, so it should not be used for long periods
papulosa nigra gradually increase in size and number with age so they need to be cauterised time to time. they are asymptomatic as such but are of cosmetic concern. complete cure is not possible
for itching of face and scalp you may take allegra when needed
keep face well hydrated.
lotion will provide soothing action
use a sunscreen withspf25+regularly even if indoors
For scalp use a oat meal based shampoo and a antidandruff shampoo if dandruff is present
the time required is unpredictable and depends upon how your skin responds to the treatment
Hope this helps you
