hi i think carofit
ultra is the best cream for hyperpigmentation
than kojic acid
cream as it cont ains other products like vitamin c
,arbutirin which increases the potency of kojic acid.
It should be applied strictly over the hyperpigmented patches at the night time.it should be applied along with moiste cream if there is irritation.it should be applied for 3 months.yes carotin tablets also should be taken for atleast for 6 months
