Don't use a hydroquinone product. They don't tend to work well on darker skin. Hydroquinone doesn't have any inhibitors in it, so as someone said, you can end up with hypOpigmentation trying to cure your hypERpigmentation, so little light spots everywhere and then you're kinda screwed because there aren't many (if any) products available to correct that. Also, hydroquinone products have been linked to liver diseases, and you can only use it for 3 months at a time, then you have 3 months off of it, then 3 months back on.
Use a sunscreen of course. I get really bad dark spots after a blemish (stop picking BTW you're only hurting yourself) and i'm using Ole Henriksen's "Three Little Wonders" which includes Truth Serum Collagen Booster w/ 10% Vitamin C, Invigorating Night Gel, and Sheer Transformation Creme.
Truth Serum Collagen Booster: Has 10% vitamin C, a known skin brightener and potent antioxidant. Apply it to the face and throat AM and PM, you'll see results in like 2 weeks, and the longer you use it, the more rejuvenated the tone and radiance of the skin is.
Sheer Transformation Creme: Is oil free, very light weight and packed with botanical brighteners. Ester C, Kojic Acid (Gently aggressive brightener) and tons of Vitamins packed into this one. It moisturizes really well, it doesn't leave behind any residue.
Invigorating Night Gel: NIGHT TIME ONLY. This has botanical brighteners as well as Alpha Hydroxy Acids to fight blemishes and exfoliate the surface layer of the skin, where your hyperpigmentation is most visible. I apply the sheer transformation on top of this gel, as I don't find it hydrating enough, but I also like having the extra benefits of brightening and evening out my skintone.
It sounds like a lot to put on your face, but honestly my face has never looked better. I haven't worn foundation to work for the last 4 days and people have been commenting on how clear, even and radiant my skin looks. The Three Little Wonders comes in a kit for $65, but it's $132 to buy the three products individually, so I'd honestly say you're definitely gonna get your moneys worth, and they last forever. I've gone through only 2 jars of Sheer Transformation in 5 months, which is quite a long time considering I'm using a generous amount twice a day.

Good luck, I know how frustrating it is to have little brown (or blackish brown for me) spots and not be able to treat them the same way our lighter counterparts can. I've tried everything, even considered a few dermatologist treatments (very expensive) but the Ole H kit has worked really well for me.
we've also just started carrying a new brand, Rx for Darker Skin, I haven't personally tried it, but I hear good things.
