Hello,
For these black spots, without treatment, this usually takes about 6 months to resolve and for the skin color to go back to its normal color.  Topical treatments with acids and chemical peels can be effective but can take a while for the skin to totally revert to its normal color.  Microdermabrasion can also be done, but this might require several sessions.  Skin resurfacing using lasers is also an option.  

You can discuss these treatment options with your dermatologist.

I hope it helps. Take care and regards.
