Hello experts, Greetings of the day! I was on treatment for Acne from 12/12/2022 to 6/1/2023. I was prescribed epiduo, my skin started getting clear but I got a grey patch near my mouth and eye. After exposure to sun the same patches turned brown and the one near eye got peeled and was red from inside. Seeing the situation I ran to the dermat on 6/1/23, he said my skin is peeled completely and stopped epiduo. At present I am using Cetaphil DAM moisturizer in day and applying calosoft af lotion overnight. I have just finished 7 days dosage of medirol 4 mg as prescribed by the dermat. My skin near eye and mouth is still dark compared to face. Is this curable and can I get even skin tone? Please help me understand the treatments available and how much time will it take to get back to normal. Looking forward to hearings. Thanking  in advance.
