Hi. Greetings. This could be pityriasis alba or a fungal infection. You could send me further queries on private follow up chat with pictures of the lesion and I could help you with that or see a dermatologist near you. Use a sunscreen for a More even skin tone. Take a zinc based
vitamin supplement for a month. Hope this helps. Warm regards Dr Govind Suresh Mittal, excel care hospital Bangalore
