Azelaic acid topical acid, kojic acid, and tretinoin (Vitamin A derivatives.) These are available worldwide. Other options include superficial to medium depth chemical peels with agents like trichloroacetic acid. Also, covering makeups are useful for some circumstances, as are sunscreen preparations to help prevent further darkening.
I suggest consulting with a physician experienced in all these modes, and starting with noninvasive methods, like creams, first.
Best.
