welcome to healthcare magi forum
thank you for your query
i understand your concern about fair skin .
and should not use more than 4 weeks
it must be used under prescription of dermatologist.
it can cause skin thinning and permanent damage.
do not use the cream .
fair skin color is nature gifted .
you should accept your skin color and try to make skin to glow and shine
better to consult dermatologist
i hope i answered your query
