Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Perhaps you have Post Inflammatory Hyperpigmentation. If I was the treating doctor I would suggest you to use Tacrolimus 0.1% ointment, twice daily for the white spots. Rub it in. Use it for at least 2-3 months. It is a prescription medication and i advice you to kindly talk to your local practitioner for a prescription of the same. Hope I have answered your query. Let me know if I can assist you further.
