Thanks for writing to us.
Firstly it is important to know whether the darkness of toes or fingers is a primary phenomenon or it occurred secondarily to some eczema, chill Blains etc. so that a proper treatment can be offered.
Emoderm is an emollient or a moisturising cream and it would rarely induce itching.
To relieve itching, take tablet cetirizine
and apply a steroid cream like betamethasone
. Once the itching is gone, pigmentation can be reduced with an emollient cream containing Glycolic acid
, urea etc ( Xerina cream)
Hope that helps
