Best to take a course of Bcarotene tabs.Aloe vera cremes may suit you.
Hello,
The treatment for such dark spots and hyperpigmentation includes various skin creams like hydroquinone, azelaic acid, corticosteroids, tretinoin cream and laser treatment.As you have a sensitive skin,so any of these is not recommended.Apply calamine lotion and aloe gel. 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.
Hope it helps.Take care and pls do keep me posted on how you are doing or in case you have any additional doubts.Kind regards.
