thanks for using Health Care magic .
I would be pleased to answer your question
For the hyperpigmentation
, the best option is to get your skin exfoliated by a better method like a glycolic acid
peel done every 15 days . A better option for you would be to visit a Dermatologist
to avail of these peels . Alternative peel treatments like trichloroacetic acid
are also very useful .
i would suggest you get your skin examined by the dermatologist .
for a home based treatment , Application of Vitamin C
based serum can be safe over long run.
Thanks and take care .
