Hey tuscan this is a very comprehensive summary I saw and copid for you to read and it's the basics you need she highlighted that if you are very dark you could use hydroquinone BUT on a short term basis because of the negative long term effect... goodluck

If you are looking for brightening and a little bit of lightening then consider using makari or buy a skin lightening kit at skinactives.com.
Sun screen (especially proection against UVA which is what causes skin darkening), vitamin C serum (10-30% concentration), AHA peels( like glycolic acid or lactic acid. Daily at no more then 10% and weakly get that done professionally), microdermabrasion or enzyme peels, retinol or Retin-A. all these treatments help to brighten and smoothen the skin while allowing other topical treatments to penatrate deeper so that they work better.
There are suppliments like glutathione (injections cause pills don't get absorbed readily through injestion), vitamin C, A and E, selenium, cysteine, Alpha Lipoic acid, MSM, Whey protein, melatonin, glysine and glutamine.
There is also the typical Hydroqinone but that's better for sort term (no more then 4 months) treatments for hyperpigmentation but it has potential for lightening the skin complexion. There is a risk of ochronsis but that risk can be reduces if you use HQ properly. At no more then 2% for no more then 4 months then maintain with another skin lightener.
There is also fast treatments like Hydrogen peroxide (etta's bleaching powder). I don't know what would be a safe and effective concentration to do this treatement but etta has a line of cosmetics that seem to work well on even the darkest skins. HP is relatively safe but very irritating and drying to the skin. Our bodies produce HP naturally to help oxygenate tissues and some people will acutally go to doctors and get HP injections for health benefits and anti aging. There are people who produce too much HP in the skin which causes their skin to be bleached from the inside out ( non as some forms of virtiligo). HP is used in skin oxygen facial masks at spas and its also used to bleach dark facial hair. There are different grades of HP and only use a product with cosmoseutical grade and never mix up our on batch at home.
There are other skin lightening actives, arbutin, kojic acid, lemon bioferment, bearberry extract, mulberry extract, licorice root extract... products like Euoko Carrara collection has a pretty good list of some popular and effective skin lightening actives. I wouldn't bother with euoko cause the stuff is so expensive but you can note the actives and compare with other products out there.
Hope this helps.
