Your doctor has prescribed aptly for your concern and has given a combination of mild pigmentation reducing cream ban a tan in morning and a potent pigmentation reducer melalite in night. Melalite is a triple combination cream containing hydro quinone, steroid
. It is a strong cream for night use and should be used only under doctor's guidance. If used correctly as per doctor's advice it reduces pigmentation quite effectively without any side effects. However long term use beyond one to two month and abrupt discontinuation of use can cause rebound pigmentation. Ban a tan cream contains liquorice
and arbutin and can be used for prolonged period. I would suggest you to follow your doctor's prescription and remain in follow up till your skin improves. Hope that solves your query. Take care.
