Mnb07040 what kind of light spots are they? Yeah I agree retin-a, aha peels, are among the few that may help. If your only trying to blend the lighter spots on your face, you may not want to depig since this may only add more white spots on your face until you completely depig. My guess would be that once you completely depig you are unable to tan, as your melanocytes cells are then destroyed. You may want to try something milder such as a tyrosinase inhibitor product
