A member asked:

Can hydroquinone effectively treat the brown scars of lichen planus on my shoulder and bikini line?and how much should i take it 4%?

A doctor has provided 1 answer

Can help: Hydroquinone 4% is available by prescription and is more effective than 2% which is available over the counter. It can help reduce the dark discolorations but probably not remove it completely. Use for a couple months. Important not to keep using continuously without a break due to side-effects.
