Hydroquinone can be very bad for your skin especially if used for long periods of time. Not the most reliable source of info, but wikipedia backs that claim up. Like Babakins said, HQ is known to make treated dark spots or body parts darker in the long run. Additionally it can cause your skin to thin. You could try more natural remedies (i.e. lemon juice, papaya soap, kojic acid soap) with a very good sunblock (rain or shine). If you're looking to lighten your face and neck more than just a bit, I'd look into getting facial peels, start of with something mild like lactic acid. I recommend that you have the peels done professionally.
