Hello,
The treatment for such hyperpigmentation includes various skin creams like hydroquinone, azelaic
acid, corticosteroids, tretinoin
cream and laser treatment. But please use it under a dermatologist’s guidance. If it still persists then you can go in for laser treatment, Chemical peeling or microdermabrasion. Avoid picking, harsh scrubbing, and abrasive treatments unless prescribed by a dermatologist during this period.
I hope it helps.
