Exogenous Ochronosis -- Try VI Peel
Dark Skin and Hydroquinone
If you do have ochronosis I would NOT use the Hydroquinone, now or in the future.
If you have hyperpigmentation of another cause, I would be clearer about the specifics of your particular situation before starting any other treatment protocols. Only a highly qualified Dermatologist with lot's of experience in this arena should direct your future therapy. Mismanagement at early stages can lead to further darkening and sometimes, a situation that cannot be completely remedied. Good luck with your skin.
