Thank for asking to HCM
I really appreciate your concern the history given here for the dark patches that you have might not be due to the hormonal
problem this could be hypersensitivity
reaction that might be affecting the pigmentation, I usually try " Hydroquinone
cream with beclomethasone " this gives good result I would like to advise you to better have opinion from the dermatologist
, hope this information helps you have nice day.
